Human Builder in a NutshellHuman Builder is based on a best-in-class human modeling system which, for many years, has permitted detailed investigation into human-centered design issues in the context of a workplace before it physically exists. Human Builder provides very accurate simulation of humans and their interactions with products to ensure they will operate naturally in a workplace tailored to their tasks. The Human Builder product specifically focuses on creating and manipulating digital humans for "first level" human-product interaction analysis. Human Builder consists of a number of advanced tools for creating, manipulating and analyzing how manikins (based on the 5th, 50th and 95th percentile value) can interact with a product. The manikins can then be used to assess the suitability of a product for form, fit and function. The manikins can be intuitively created and manipulated in conjunction with the digital mockup to check features such as reach and vision. A simple-to-use interface ensures that first-level human factors studies can be undertaken by non-human factors specialists. Tools contained within the Human Builder product include manikin generation, gender specification, percentile specification, direct kinematics and inverse kinematics manipulation techniques, animation generation, monocular, binocular and ambinocular vision simulation, as well as vision output cones.

Before Reading this GuideBefore reading this guide, you should be familiar with basic Version 5 concepts such as document windows, standard and view toolbars. Therefore, we recommend that you read the Infrastructure User's Guide that describes generic capabilities common to all Version 5 products. It also describes the general layout of V5 and the interoperability between workbenches. You may also like to read the following complementary product guides, for which the appropriate license is required: Human Posture Analysis Human Measurements Editor Human Activity Analysis

What's New?New FunctionalityReporting Capabilities This functionality produces comprehensive report files from specifications. This gathers the results of the various analyses found in the Human workbenches including an analysis of the manikins vision. Manikin eyes following the 3D compass with Reach and IK Mode This proposes a more natural behavior for the manikin's vision when it is performing a reach or IK on an object. The vision of the manikin is directed to the object the manikin is trying to pick up, which would be more like a human. Changing the Manikins color of their eyes, mouth, and hair Through a dialog window, you will be able to change the color of the manikin's appearance. This dialog window will display a choice of colors for each of these three components, the color of the lips, the eyes iris and the hair/eyelids/eyebrows. Keeping the Relative Position The Keep Relative Position option allows the user to change the way the attach will react when it is modified.

Enhanced FunctionalityNew Table of Contents The table of contents has be changed to help in the ease of use. Redefining the Segments Offset - Creating multiple offsets The user also has the possibility to create multiple offsets for the same segment and to decide which one will be the active offset at the current time. Furthermore, the segment's offsets can be exposed in the knowledge "f(x)", for the Publication. This is useful mainly in the manufacturing scenarios where the manikin is taking care of multiple tools within a same simulation or workstation. Each tool can then have its own offset specified on the manikin's hand. Reset the Target function for Fix and Fix On Constraints This functionality gives the user the possibility to reset the target of a fix or a fix on constraint. This will considerably reduce the time for resetting a constraint, as previously, the user had to delete the old constraint and create a new one. Data can be saved in the Catalog This will include angular limitations properties, Appearance properties, offsets and reports. This data will be modeled and saved within the existing CATSwl files, to which the catalog elements will point, as it is the case for other manikin data that can be reused by the user. Modification of the Whole Graphical Properties of the Manikin This will make the Properties Panel more coherent and groups all the related data together in a unique tab instead of multiple copies of the same tab. The Manikin Attribute Organization PPR tree This will make the the organization of the PPR tree more coherent and groups all the related data together. Integration of Clash Analysis in all Manikin Manipulation modes This provides full integration of all clash detection capabilities to the manikin.

Human Builder


Page 27

Father product: Since manikins are created inside CATProduct documents, you must select the Father product by clicking the desired document in the specification tree. The Father document's name will automatically be placed in the read-only field.

The Father product is the product that the manikin will be attached to in the specification tree. It can be the root product or any other product under the root.

Please note that the Father product cannot be another manikin. Manikin name: In this field, you can enter a name for the manikin i.e., Driver, Passenger, Machine X Operator, etc. This name is typically used to identify the manikin within the document. Several manikins may have the same name. Please note that if you leave this field blank, the default name will be Manikin1 (2, 3, etc.), and the manikin will be saved under Manikin1.CATProduct.

Gender: In this field, you must choose whether the manikin will be a man or a woman. Percentile: You can choose the percentile (between 0.01 and 99.9) that the new manikin will be built from.

Human Builder


Page 28

The percentile is applied to the stature (height) as well as the weight of the new manikin. It indicates the group the manikin will belong to within the ordered statistical population. In other words, the stature and the weight of the new manikin are both set at the chosen percentile except the 50th percentile, where all the variables are then set at the 50th percentile. All other anthropometric variables are estimated according to the population chosen.

Optional tab

Population: In this field, select the nationality of the manikin from the default set of populations: American, Canadian, French, Japanese, or Korean. Model: In this field, choose the model-type desired: whole body, right forearm, or left forearm. Referential: In this field, choose the initial referential point of the new manikin. The choices are: Eye point, H-Point (default), Left foot, Right foot, Lowest foot, and Crotch. For more information, see the Referential example below. Set Referential to Compass Location: If this parameter is activated, you will be able to assign the initial position of the manikin with the compass, i.e., a plant floor. If the parameter is not activated, the manikin will be displayed at its default position (world origin). For more information, see the Referential example below.

Referential example

Saving a ManikinThis task describes storage management principles involving manikins in the Human family of products.

A manikin is created in the same document as its father product, thus avoiding file duplication in the saving process. Manikins created in such a manner can further be imported into a new document, and most importantly, manikins created with previous releases of the software will import as well, without any particular required operation from the user (no data migration needed). There is no duplication of files on the user disk unless it is really necessary.

1. To save a manikin select File > Save As...

2. The file Selection dialog box appears. Select the directory that you would like to save the manikin in.

Copy/Paste/Inserting a Existing ManikinThis task describes storage management principles involving manikins in the Human family of products.

A manikin is created in the same document as its father product, thus avoiding file duplication in the saving process. Manikins created in such a manner can further be imported into a new document, and most importantly, manikins created with previous releases of the software will import as well, without any particular required operation from the user (no data migration needed). There is no duplication of files on the user disk unless it is really necessary. Each manikin created is local to its document, and copying a manikin from one CATProduct document to another will require you to explicitly break the link with the Copy/Paste Special command.

1. If you want to import an existing manikin, use the Insert Existing Component command of the Product Structure workbench.

2. Please note that when working with CATProcess documents, the behavior of a manikin inserted as a resource will not change. That is, this does not apply to manikins imported in a CATProcess document. Also note that manikins created in previous releases of Human Builder (those in their standalone documents) will continue to behave as such (they will not be merged with the document they are imported in). 3. The command prompt asks for a component to which the existing component will be added. Click on the Product1 in the PPR tree.

Human Builder


Page 39

4. The File Selection dialog box appears. Select the directory, and manikin required, and Open.

5. This places the manikin into the scenario.

Manikin tree organizationThese are some functions available in the Manikin tree organization using Human Builder: Manikin Attribute Organization Using the Sub-Tree

Human Builder


Page 41

Manikin Attribute OrganizationA node for each manikin attribute is displayed under three main sections in the PPR tree.

Bodyq

Note that the Spine node is made up of a Lumbar node and a Thoracic node, not individual vertebra segments The Line of sight node is located under the Body section.

q

ProfilesThis section contains all general (not specific to a segment) attributes intrinsic to the manikin.

SettingsThis section contains the attributes used for setting the manikin in its environment through posturing and positioning.

Using Manikin Attributesq

Right-click on any individual node or on a manikin node and choose Properties from the contextual menur

Individual node: View or edit the properties of any attribute. Manikin node: Each attribute displayed in the specification tree has a corresponding properties tab in the manikin's properties dialog box. These include Offsets, Angular Limitations, and Preferred Angles.

r

q

From the PPR tree, select a single attribute or select a combination of attributes (and specific segments, if desired) using the Ctrl key Save manikin attributes within catalogs. These manikin attributes are selected directly from the PPR tree. Cut/Copy/Paste attributes from one manikin to another. Right-click on one node and execute available commands (Reset/Swap/ Mirror Copy) for the selected objects (attributes). r Note that the command is applied on all the selected attributes.r

q

q

q

CAUTION: If body segments are selected alone (no attributes are selected) and a command invoked, the result is exactly as if ALL ATTRIBUTES ARE SELECTED. For example, right-click on the Right Arm node and select the Reset command. The result is that everything applied to the right arm is reset (posture, position, locks, angular limitations, preferred angles).

Edit the Vision ParametersThis task describes the Vision function and how to set and edit manikin vision attributes. Using this function, you will see a scene through the manikin's eyes, displayed in a separate window. Just like humans, a manikin can see its environment. Manikin vision can be with both eyes or limited to only one eye. Even the blind spot is simulated.

The Manikin eyes follow the 3D compass with Reach and IK ModeThis proposes a more natural behavior for the manikin's vision when it is performing a reach or IK on an object. The vision of the manikin is directed to the object the manikin is trying to pick up, which would be more like human behavior.

ReportsThese are the tasks that crete Reports of a Manikin using Human Builder: Reporting Capabilities

Human Builder


Page 81

Reporting CapabilitiesThis functionality produces comprehensive report files from specifications. This gathers the results of the various analyses found in the Human workbenches including an analysis of the manikin's vision. The general concept for the reporting capabilities is the report object that is capable of extracting output information from the different ergonomic analyses, and dumping this information into a formatted text or html file. This creates and customizes one or several report objects, and activate/deactivates those at any given point in time. Each report object is assigned to a specific manikin and associated to an output file (the log). The updating of these logs can be activated by using the Update command for Human Builder. For Human Task Simulation, activate the Update Analyses During Simulation, in the Tools > Options >Ergonomics >Human Task Simulation > General Tab. There is also a Vision analysis in the list of possible reports on the manikin. This report contains the length of the line of sight (focal distance) and the snapshot (image) of the manikin's vision window. The benefits that allow you to save the outputs of human static analyses into formatted text files are:

q

The analysis results can be consulted more efficiently, and individual results can easily be compared together.

q

The resulting files can easily be processed and reformatted (in Microsoft Excel for example), in order to be presented in a different context (management report, web page, snapshots for presentations).

q

With the report objects, it is possible to run ergonomic analyses without opening the corresponding panels and without switching workbenches (all analyses are done in the background).

q

Ergonomic problems can be identified more quickly and easily, and corrective actions can be taken earlier.

q

With the Vision analysis, you will get a image of the vision of a specific manikin at a certain moment in time. This will allow you to enhance their analysis capability and therefore help validate that the manikin is positioned in the right places to view their environment correctly. In the list of possible reports, you will have an item Vision Analysis. This report consists of the value of the line of sight and the image of the manikin's vision window.

Human Builder Report Procedures1. In the Human Builder workbench select the Inserts a new Report menu bar or in the Manikin Tools toolbar. 2. Selecting the Inserts a new Report command, you are then prompted to select a manikin the new object will belong to. Once the manikin is selected, the Report Definition panel appears: command that is located in the Insert

3. You can choose any combination of analyses to populate the report, by toggling them from the Available column to the Selected column. The Output File field contains a default path, pointing to the V5 temporary directory (CATTemp), but you can change the output file of the report by clicking the File... button. This field also contains a history of the last few report files used (hence the combo). If the output file name's extension is . htm or .html, then the report written to this file will be in html format, Otherwise, the report will be written in text format. Each report object must be associated to a specific log file; however, it is permitted to assign two or several different report objects to the same log file.

5. Any combination of analyses can be activated, and each report object must point to a valid output file. A specific analysis in the above list will be selectable for activation only if the proper product license check succeeds for this analysis. For instance, the Push/Pull and RULA analyses will be selectable only if the Human Activity Analysis product is installed. 6. While editing the report properties, clicking another manikin will switch that report object to the new manikin. The name of the manikin associated to the report object appears in the Manikin field. Also, a default name (i.e. Report1 Report 2...) is given to the report object. Change the name before you click on OK. 7. When completed, the new report object appears under the selected manikin, in the specification tree:

Human Builder


Page 84

8. Descriptions can also be created for the vision, the anthropometry, or the posture of the manikin using the Adds a description to a manikin object command. Select the appropriate node in the specification tree (Manikin, Anthropometry, Vision, or Body) and the corresponding description will appear in the text field.

9. After configuring the report object for a specific manikin, the launch of the Update

command in the

Human Builder workbench. This will cause each active report object to update, and each object will send the results of the activated analyses into its respective log file. Please note that the dialog panels of the corresponding analyses do not need to be open for the report objects to work. That is, the relevant analyses are performed in the background, using the manikin's current posture, and no message panel pops up during the process. 10. Also note that the Auto Update feature will not interfere with the log production. That is, even if the constraint Update mode is set to Automatic (through the Tools > Options panel of Human Builder), click the Update

button in order to get the log updated. 11. The Update command will therefore have two distinct functions: update the constraints of each manikin in the current document (if any), its current function, and then, perform an update of the log for each manikin of the current document that has at least one report object activated. Each click on the Update augments a given log file, without overwriting the previous information appearing in that file. At any given time, you can view a log file by other means than V5 (i.e. Notepad, Internet Explorer, Microsoft Office) to verify its contents. If an activated analysis points to a target log file that does not exist, then that log file is created by its report object and populated on the next click on Update. If, at that time, for any reason, the log file, cannot be written into (because of bad file access permissions for example), then the appropriate error panel informs you of the situation.

13. The Cut, Copy, Paste and Delete commands are straightforward. The activate/deactivate commands can be used to activate/deactivate a given report object. Inactive report objects will NOT produce an entry in their respective

log file when the global Update

command is launched.

14. The Update command in a report object's contextual menu can be used to force an active report object to update its log file, using the manikin's current posture. It is this command which is actually called upon in the background on every active report object when the global Update command (from the workbench) is executed. You can also use the Update command on the contextual menu of the Reports node, to update all active reports of one manikin in one operation. 15. The Show Log... command in a report object's contextual menu will open a read-only window displaying the contents of the log file associated to that report object. Every time the global or local Update command is launched, the content of that window is updated automatically. Please note that the Show Log... command is available only on active report objects. The Edit command pops up the Report Properties panel, just as when double-clicking the object.

Inverse Kinematics BehaviorsThese are the tasks that create Inverse Kinematics for a Manikin using Human Builder: Inverse Kinematics Behaviors

Human Builder


Page 101

Inverse Kinematics BehaviorsThe Inverse Kinematics (IK) mode gives you the capability to manipulate the manikin's IK with designed behaviors. This function is principally for moving the upper body in relationship to the manipulation of the arms and legs. This manipulation will eventually induce spine and/or hip motion in order to translate and orient the manikin toward the target. In other words, these behaviors will modify the IK chain, making it local (limbs only) or global (limbs and spine and pelvis). Two commands are available in IK mode and either may be used depending on the need or the operation to be performed (making a new posture or fine-tuning an existing posture). Both commands provide easy access to manikin IK capabilities. The only difference between the two is in the compass orientation (as illustrated below). These commands are mutually exclusive; activating one automatically deactivates the other. For more information, see Using the Inverse Kinematics Modes. This example uses the IK Worker Frame Mode and covers the following topics:

Page 102

in the Manikin Posture toolbar and select the manikin's left hand. Move the

manikin's left hand and observe the IK behavior.

The manikin's IK behavior is currently the default Limb IK chain. If no other behavior option is selected, the IK manipulators, i.e.,

IK Mode, Reach Mode, will drive the arms and legs in order to simulate natural motion. Note that all the options are not mutually exclusive; more than one item can be activated at the same time. For example, activating both the Thoracic and Lumbar options will initiate motion of the entire spine if the target cannot be reached by extending the arms. If multiple Pelvis options are selected, the manikin's pelvis will move (translate, rotate, or laterally orient, depending on the option selected) with or without preliminary spine motion, depending on the selection status of the Spine option.

Segment TwinsThis functionality is available only for the IK and Position Orientation Reach commands. When the compass is snapped on a hand or foot in IK and Reach Mode, an image of the entire hand or foot in its current posture will follow the compass. The image will stay there until the IK or Reach mode is exited.

OffsetsThese are the tasks that create Offsets for a Manikin using Human Builder: Creating Multiple Offsets Redefining the Segments Offset Publishing a existing Offset

Human Builder


Page 127

Creating Multiple offsetsIf required, you have the possibility to create multiple offsets for the same segment and to decide which one will be the active offset at the current time. This is useful mainly in the manufacturing scenarios where the manikin is taking care of multiple tools within a same simulation or workstation. Each tool can then have its own offset specified on the manikin's hand. The offset command in the human builder workbench (also available within the Human Task Simulation workbench in the DELMIA portfolio) will create a new point identified by a small cross . This point is linked to the segment and will be used as an offset. If

the segment selected is the pelvis (phantom segment), you will be able to set an offset directly on the H-Point location. Offsets will now have a 3D representation in the 3D viewer. The hide/show command, as well as the name and color edition in the properties command of the contextual menu will be available. Also, this modifies a currently existing functionality: redefinition of offset. An old file loaded into the new version of the program will create an offset and automatically activate where the old redefined offset was. Also, these offsets can be saved and loaded in the catalog.

1.

For creating an offset, the user will have to click on the icon, Inserts a new offset manikin's segment. The Offset dialog box opens:

and select a

The name field will allow you to modifying the name of the offset at the creation and edition. The manikin field will allow changing the manikin on to whom the offset should apply, during creation, or allow the migration of an existing offset to another manikin at edition time. When selecting another manikin at creation, the compass will place itself at the currently active offset position, and when choosing a new manikin at edition, the compass will move to where the new offset is (effectively mirroring the offset position to the new manikin). Selecting OK, the old offset would disappear and a new offset would be created. The segment selector changes the segment onto which the offset will be placed during creation, or migrate to an already existing offset to the new segment at edition time (a segment on another manikin is also possible). When selecting a new segment at creation, the compass will go to the currently active offset, and when selecting a new segment at edition, the compass moves to the same relative position it had before on the new segment (mirroring the offset according to the new segment's position).

Redefining the Segments OffsetThe Offset command is used to redefine the behavior of the Reach Mode. The Reach Mode's default behavior is to make the end point of the selected segment or skin point reach the compass location. The Offset command allows you to transfer that "end point" to another point in the 3D space, which will then be used to perform inverse kinematics. An example of this would be when the manikin must perform some inverse kinematics while handling an object. In redefining the offset, the compass may be also be snapped to manikin skin points. Thus, the subsequent reach operation is resolved from the skin rather than the central point of the segment. There is the possibility to create multiple offsets for the same segment and to decide which one will be the active offset at the current time. This is useful mainly in the manufacturing scenarios where the manikin is taking care of multiple tools within a same simulation or workstation. Each tool can then have its own offset specified on the manikin's hand.q

The Offset feature can be redefined for any segment or skin point of any manikin The Offset feature is not available on the forearm model The name field will allow modifying the name of the offset at creation and at edition. A list of those offsets will be possible with one active offset at a time.

Redefining the offset to a point on a partThe goal of this task is to transfer the end effector of the manikin's right hand to the tip of the tool the manikin is holding. This is done so that when the Reach Mode is applied to the right hand, the inverse kinematics will be transferred to the tip of the tool. The tool will then do the reach on behalf of the hand segment. 1. From the main menu, select File > Open. The File Selection dialog box appears.

2. Select the Offset.CATProduct file from the samples directory.

The Name field is used to name the offset. The system will assign an automatic name (i.e. Offset1, Offset2,...), but you can override this name at your convenience. The Manikin field indicates the name of the manikin owning the offset. By selecting this field, you can switch manikins, that is, transfer the offset to a different manikin. The Segment field (and the Right/Left combo beside it) indicates the current segment that owns the offset being created/edited (in the snapshot above, the offset will be created on the right hand segment). By selecting this field, you can change the segment assignment of the offset, or transfer the offset to another segment. The Activate checkbox allows you to toggle the activation and deactivation of the offset. In the snapshot above, the offset is currently active. The Value frame displays the current location of the offset, in terms or translation (first row) and rotation (second row). This frame also incorporates a Reset button, which repositions the offset back to the origin of the segment, and a Reverse Compass button which reverses the Z direction of the compass. The Cancel button cancels the creation/edition operation.

9. Place the compass at the tip of the tool. This is the desired location for the inverse kinematics.

10. Select the OK button.

11. The offset is now transferred from the hand to the tip of the tool (green X).

6. From the Manikin Posture toolbar, select the Reach (position only) icon.

7. Using the red handle, move the compass to the top surface of the table.

8. Select the manikin's forearm. The forearm's offset point reaches the compass point on the table.

When editing the offset of any segment, the compass is automatically placed at the current offset location. The default offset location is the end point of the segment being edited. To reset the offset back to its default value, open the Offset dialog box on the segment and click the Reset button. Click Close to close the dialog box. The Reverse Direction button reverses the current orientation of the compass. This feature is typically used when the geometry is manipulated in design mode where the compass goes inside the geometry when snapped to an object.

Publishing a existing Offset1. Once created, the offset can be published using the published command in Tools > Publication

2. This publishes a point that represents the relative position from the segment-end. Select the X from the 3D geometry window. This point is listed underneath the Publication node as shown.

3. So, for example, it will be possible to create an assembly constraint between and object and a published offset.

4. In the Knowledge toolbar, ware or the F(x) Formula command.

the offsets coordinates can also be modified by the knowledge-

5. The compass snaps to the currently active offset, or the default offset (0,0,0) if no user-made offset exists, or if they are all deactivated. You would then move the compass around, and when the position and orientation suits your needs, click OK to create the new offset. The compass position is dynamically updated into the labels called Value as it is moved. A new checkbox Activate automatically activates the new offset once it is created. If it is not checked, the current offset will not be activated, even though the offset will be created. Any numbers of offsets can be created per segment, but only one can be active at a given time. Creating a new active offset on a segment that already has an active offset will deactivate the old one. The same dialog box is used to edit the offset. The edit command would be available from the contextual menu of an offset, and would open the dialog with the compass positioned at the offset. The reset button would move the compass back to the default position (0,0,0) (except for the hand, where the default position is different, and the reset would place compass on that position). When the dialog is open, all the created offsets for the given segments are still shown, but they cannot be modified during the creation or modification of another offset.

OffsetsThese are the tasks that Attaches to a Manikin using Human Builder: Attaching an Object to a Manikin Segment

Human Builder


Page 144

Attaching an Object to a Manikin SegmentThe attach function creates a one-way relationship between a manikin segment and one or more objects in its environment. The attached object becomes a slave to the segment. Once attached, this object will move with the same matrix as its master segment. This task is divided into three parts: Attaching an object to a manikin segment Checking existing attaches on a specific manikin Detaching an object from a manikin segment It is important to note that the attach is a one-way relationship; the object follows the segment, not the opposite. If the object is moved (i.e., using the compass) after the attach is made, the segment will not follow the object's motion. When doing any attach, the compass may be snapped to manikin skin points, not just the central point of a segment. Refer to the status bar for information and instructional prompts.

The user could also select the Load from Manikin Attributes from a Catalog command

and choose

Attach_sample posture from the "Attach" catalog. This places the manikin posture so that it appears to be handling the tool with its right hand.

4. Select the Attach/Detach icon.

5. Select the object to attach (in this case, the tool). 6. Select the manikin segment to which the geometry will be attached (in this case, the manikin's right hand). 7. If there is multiple attaches, the Attach/Detach dialog box appears.

8. Once the object is attached, it will follow the motion of its master segment. Move the hand (master segment) using forward kinematics and inverse kinematics. The tool will follow the hand's motion. This is also the case when a posture is applied to the manikin or if the manikin as a whole is moved within the 3D environment.

1. Access the properties of the newly-created Attach. To do this, in the specification tree, expand the Attaches Node.

2. It will be possible to cut, copy, and paste the individual attach nodes, or all the nodes using the Attaches node. 3. Several options will be available through the contextual submenu: Deactivating the attach objects will turn them off. They will still be in the tree, but will not be effective until turned back on.

The edit command will open a panel through which changes can be made to the selected Attach.

Using this Edit panel, it will be possible to rename the Attach, to transfer it to another manikin segment, or side or object.

The Keep Relative Position option permits you to change the way the attach will react when it is modified. When the option is disabled, the object's position in space will remain the same even if the attach relation is changed. In this mode, the Attach is only a means to move the object simultaneously with the segment. On the other hand, if t
