Preface The objective of this training manual is to make students familiar with the Bentley Software and its working. As part of the exercise different teams need to derive alternative concepts and taking care of different constraints encountered. Its purely Students innovativeness/ideas to develop alternatives for the same purpose. Students/teams are encouraged to try different alternatives and use their imagination to develop new approaches towards the Site Designing. After putting their design concepts, they can bring liveliness to the plan by putting cells/objects like trees, buildings, men, cars , vehicles, buildings, etc. Movable objects can be moved on road like cars, vehicles etc. Men can be shown moving on the footpaths. The whole purpose is to expose students to latest software technologies.

Methodology Base map that is given to you is a contour map of an area where Residential Accommodation is planned during Commonwealth Games in Delhi in 2010. This base map is the starting point of the exercise. It is a 3 Dimensional Topographical map showing locations of existing features like buildings, existing roads etc. Steps to be done to carry out project are Put first road/route

1. Put centerline, horizontally and vertically 2. Put road edges 3. Put shoulders 4. Put toe lines

Put second road (can intersect first road , or can start/end at first road) 1. Repeat above steps 2. Be careful while doing vertical design, that levels at intersection

are important Put more road/route alternatives(depends on Students conceptual plan) Put roundabout/junctions along the intersection of the roads As per your desired concept bring Buildings (Activities proposed by

Students) from the given Microstation Cell library and place them in the proposed site as required.

Place other objects like Vehicles, men, trees and other required cells from the Microstation Cell Library to bring reality to routes.

Render them Do animation/ visualization on the above. The above are general steps to be followed for completing the project Details of all the above options are written in the subsequent pages. Follow the steps mentioned and it will be quite interesting to do the innovative things.

1. Parameters - Here you set the default radius and transition parameters. Use a standard value for the scheme and change individual curves as necessary. 2. Add an IP - This allows you to add intersection points by clicking on the drawing. Subsequent intersection points will be connected with a straight. Adjacent straights will be connected by a curve and a transition. Dont worry if two curves overlap - you can correct this afterwards. 3. Move/ an IP - You do this by dragging and dropping an intersection point. The moved IP will stay where it was dropped unless the snap to point icon is live and the IP was dropped onto a string. In this case it will snap to the nearest string point. Another option is to the IP along a tangent. The IP will along the tangent opposite which the cursor is depressed, leaving the bearing of that tangent unchanged. 4. Insert IP - An IP will be inserted between existing IPs. 5. Clearances - Check distances between your design and other known points. You can do this by using a line or a circle. Depending on the nature of the design it may be better to define any specified clearances and then design around them.

1. The vertical alignment toolbar is similar to the horizontal, but has additional functions relating to IP movement and surface snapping. In addition, you may adjust the horizontal-vertical scale relationship to suit the need of the site. 2. As the cursor is moved over the drawing its chainage and level shown, and the running cut-fill balance is displayed dynamically on the toolbar. If the gradient exceeds the defaults set by you the value is displayed on a red background, immediately drawing attention to the infringement. 3. You can snap to a surface - the current snap surface is indicated by the coloured square on the toolbar. Change to the required surface as necessary. 4. The vertical profile will be built using the default K-values or radii for both summit and valley curves. You may amend any individual curve, either to a new K-value or radius or by supplying the new length of the curve. 5. You will be advised of any curves that overlap, or extend beyond the limits of the ground profile when he attempts to finish the profile design phase. These conflicts must be resolved before the vertical design can be completed. 6. Curve data can be supplied through the tabular input button (Table View) if required. This data may be for a new curve or for modifying an existing one. As you supply the data the graphical display is automatically updated. Also you can leave the Table View panel active while you make changes to the positions of existing IPs graphically.

Hog Curve K Value Sag Curve K Value Maximum Grade % - all gradients will be checked to ensure that they are no greater than this value. Minimum Grade % - all gradients will be checked to ensure that they are no less than this value. 2. To create a non-tangential alignment, ie, an alignment with no curves inserted at the intersection points, set the hog and sag radius values (or K values) to zero. 3. Vertical Curve Locking Vertical curve locking is used when you move an IP to indicate whether the radius of the curve should remain constant and the length of the curve change, or whether the length of the curve should remain constant and the radius of the curve change. Select Lock VC Length or Lock VC Radius as required.

1. The LC** string is used by MXROAD as the basis for all levels across the template. The superelevation functions will update the levels on the LC** string if necessary, therefore maintaining the MC** string levels intact as the original vertical profile design. This is done to ensure that you can go back to the vertical profile design phase if necessary. 2. Reference offsets are normally only used on dual-carriageways. If this offset is set to the level difference between the inner channel levels and the median level these channels will be coincident with the vertical design profile. Generally, the reference offset will be the same value as the kerb face.

1. The default arc ratios are 2:1:3, flowing in the direction of the junction fillet. The ratios may be amended, using the panel above, to suit local requirements. 2. Be careful when using this function with unequal ratios: the junction fillet string follows the direction of the side road strings and you must be aware that this may reverse the arrangement of arcs from that which is expected. Always check, using point status, and redefine if necessary.

MXROAD tidy junction removes untidy strings in junction

simple, efficient has undo function... no need to understand MX tools

1. Please note that if you intend to place traffic islands into the junction fillets it is essential that the junction is not tidied first. 2. The junction should be tidied before adding shoulders, footways and verges. 3. The untidy junction is stored in a separate model. This allows you to undo the tidying function at a later date; this is particularly valuable when a junction needs regrading at a later stage of the design.

Earthworks... create strings representing cut and fill slopes...

Reference string

Interface string

Ground section

Level datum string

Defined profileNew points

Intermediate strings

1. The following steps are used when creating the new strings :- - take a section through the ground model ( or datum level ) at the given start point on the reference string - take a section through the design model level datum string at the start point on the reference string - hang the defined profile from the level datum string coordinates and level - store the intersection point of the ground section and defined profile on the interface string - store any intermediate profile points on to their respective strings - move to the next point and repeat the procedure 2. The defined profiles consist of a series of elements. In the diagram above, the profile is made up of three elements. 3. The reference string and the level datum string will generally be the same string. This will overcome problems due to sharp divergence at areas such as bell-mouth junctions. 4. The ground model sections used may be temporary sections (automatically generated by the earthworks option) or stored sections previously created within MX.

Earthworks - string generation

Interpolated points

Reference string

Level datum string

toe-lines and intermediate strings...

gaps in intermediate strings

1. Separate strings may be created for the cut and fill interfaces or one string can be used for both. If separate strings are used, the interface strings will have gaps inserted when the slope stops and then restarts. The default is to build single strings for both cut and fill toe points. Warning - Interface strings are not amended when rerunning data - duplicate strings are generated. Therefore, before re-running the data, you should delete the old strings. 2. The intermediate strings must have different names for cut and fill features. Gaps are inserted when the slope stops and then restarts. 3. The changeover point between cut and fill is interpolated on the level datum string and is added to the interface string(s). The intersection point of any intermediate strings with the interface string is added to both strings. 4. The interface strings are 5-D strings while the intermediate strings can be either 3-D or 5-D. The five dimensions stored for each point on a string are :- X, Y, Z, Offset, Bearing 5. When the strings are drawn with the MX standard style, the offset and bearing values are used to draw the tadpoles to the correct size and in the correct direction. 6. If no toeline is found at a particular section, a warning is given. The interface strings will span the gap.

Earthworks-profile construction profiles...

consist of transverse elements.. from1 to 199 elements per profile.. most profiles may be used in both cut and fill..

elements defined by... slope (will stretch as required) or.. fully-defined by slope and width or.. slope and height..

1. The profiles used for cut and fill analysis are independent of each other, so that different profiles may be defined for each. The order in which they are to be tested is also user-definable. This gives you the ability to define cut before fill or vice versa. In the diagram below, the cut profile is defined by a single element while the fill profile has three elements. 2. It is important to remember that the strings being created are running into the page, not down along the slope.

Earthworks-styles of interface Three types of analysis available...

forward - fixed elements attached to level datum string

reverse - fixed elements attached to toe-line multi-strata - complex slopes through strata

Stretchable element

Forward style

Widths measured fromlevel datum string

Reverse style

Widths measured from interface string

Stretchable element

1. The forward style is the usual and most straightforward style. As all the elements are defined by slope and width, except the last, all the intermediate strings will be parallel to the original level datum string. 2. In the reverse style, the intermediate strings are parallel to the interface string as the widths are measured from the toeline string. 3. Both forward and reverse styles are available through the earthworks slope library.

hint - use same string as both reference and level datum for best resultshint - use same string as both reference and level datum for best results

1. The reference string is used to define the direction of the slopes, the start and end positions and the frequency of the sections. 2. It is not necessary to nominate both level datum strings - if one is not given, the slope is not calculated on that side. 3. For MX to generate the best sections, the model to be sectioned should be a triangulation model. If you have already taken a set of sections using the reference string, these could be used here.

Setting Up the Camera using Define Camera Tool

Before rendering any view scene in Microstation, one has to set up a view for better detailing. Microstation features advanced view control tools that enables to create orthogonal, isometric and perspective views. The Define Camera Tool is used set up a view for rendering graphically by manipulating the dynamically displayed view cone via handles at strategic points. Alternatively, you can use Define Camera for specific manipulations, and its settings window for precision inputs. To assist you visualize the design as you manipulate the camera, the viewing cone can be displayed in all other views. With Continuous View Updates turned on, the camera view updates dynamically as you manipulate the view cone in the other views. When used in conjunction with QuickVision, you can have your camera view displayed as a smooth rendered view as you position the camera. The Define Camera settings window lets you display only those settings that you require. With the More/Hide button you can quickly display or dismiss the more settings group box. Within this group box, Show/Hide buttons let you expand only those settings that you wish to examine or modify. Procedure to Define a Camera View

1. Select the Define Camera tool. 2. In the Define Camera settings window, turn on Display View Cone.

Apply Material

The Apply Material tool is used to:

Load, create, and save material tables. Add, remove, or modify material definitions that have been assigned

by color/level. Add or remove material definitions that have been attached to

elements in a model. Query elements for material assignments. Preview the display of materials on elements in the model. Set or clear environment maps.

Icons along the top of the tool settings window let you select the required task. A preview window displays the currently selected material. Other icons let you open and save material tables, load/unload palette files, view and edit material assignments. Material definitions are stored in palette files. With this tool you can load material palettes and apply materials from them to elements in the DGN file. Material tables apply to all models in the DGN file. When more than one palette file is loaded, the Palette setting becomes an option menu, from which you select the required material palette. Finally, you can save the assignments in a material assignment table file. When a material palette file has been loaded, you can apply materials from it to elements in your models. There are two methods by which material assignments can be applied to design elements. You can assign materials by level and color, or attach materials to elements as attributes. The latter method is particularly useful for attaching different materials to various faces of a SmartSolid. When a material is attached as an attribute, this setting overrides the assignments by level and color. When using Bentley Building products, you can attach, or remove, materials from the faces of forms. You can assign materials by level and color, either by identifying the required element, or by selecting the level and color manually. Before actually applying a material to an element, you can preview the result. By default, when the Apply Material tool is first selected for a DGN, a search is made to find a material table having the same name as the DGN file, but with a .mat extension. If this file is not found in MicroStation's default directory, or the directory pointed to by the MS_MTBL configuration variable, then the DGN file's name appears on the Table button, ready for a new table to be created.

Animation Producing Flythrough Sequences

The Flythrough Producer utility provides a set of tools that let you create simple animations called flythrough sequences in which frames specified path. Typically, a flythrough sequence is rehearsed, or previewed, in wireframe to validate the camera path and then is recorded as a series of reof stationary geometry are recorded by a virtual camera at specified intervals along a sundered images. The Movies utility (Utilities menu > Image > Movies) is used to play back these sequences and also to perform some simple editing tasks. General Procedure to produce a flythrough sequence

1. From the Utilities menu's Render submenu, choose Flythrough.

The Flythrough Producer dialog box opens. `

2. From the View option menu, choose the source view for the animation. 3. From the Shading option menu, choose Wireframe for rehearsal

purposes or the desired rendering method for a finished or nearly finished sequence.

4. Define the path that the camera is to follow and the camera target. The path can be an existing open element, or you can place an element in the design file.

5. To define the path that the camera will travel during the sequence Place a line, line string, arc, ellipse, curve, or B-spline curve to

define the path the camera is to travel. (If you do not want the path to be visible in the sequence, place the path as a construction element, or on a separate level that is not displayed in the source view for the sequence.)

From the Flythrough Producer dialog box's Tools menu, choose Define Path.

Identify the element that defines the camera path at the point at which the camera path is to begin.

Accept the element at the point at which the camera path is to end.

Select define path to choose the path along which the camera moves

Speed specifies the rate at which the movie is played calculated as 60/no.of frames per second in a movie

For example, if the no.of frames per second is 30, then Speed=60/30 = 2. If number of frames is 180, Example,for a given speed of 2, the movie will be playing for 6 seconds.

Introducing Bentley Navigator Bentley Navigator is a real-time 3D visualization program that enables you to view and interact with design files, JSpace models and related data. The Bentley Navigator enables you to open multiple, independent windows for viewing a design model. In a single session, you can display the model in separate windows and view it from different perspectives in solid, wireframe, or mixed mode. Using the full interaction with graphic and non-graphic objects, you can query the model to understand its relationships and properties. Based on these properties, you can color-code the objects in the model. Starting and Closing the Bentley Navigator Starting the Bentley Navigator is done in the same way that you start most Windows programs.

1. From the Windows Start menu, choose Programs > Bentley Navigator 2004 Edition.

2. Select the Bentley Navigator. After the Bentley Navigator program is started, the File, Settings, and Help menus display across the menu bar in the Bentley Navigator window.

2. Also, to close the Bentley Navigator, you can click the X button in the upper right-hand corner of the window.

3. If you are prompted to save the changes to the files, click Yes or Yes to All. or If you do not want to save your changes to the files, click No or No to All. or If you do not want to exit the Bentley Navigator at this time, click Cancel.

Using the Bentley Navigator Menus

After you open a file in the Bentley Navigator, additional selections are enabled on the Bentley Navigator menu bar. File Menu The File menu enables you to perform file management tasks and to exit the Bentley Navigator. Using the File menu, you can open and save model files, unlock files, manage reference and auxiliary files, and print views of your model.


B - 76

Settings Menu The Settings menu enables you to adjust the appearance of the Bentley Navigator workspace. Using the Settings menu, you can display or not display the toolbars and the status bar. By selecting Options, you can change the snap functionality, change the object selection functionality, adjust the mouse orientation and sensitivity, and modify the display of the model units of measure and the date. Also, you can enable hardware acceleration and specify the vertical axis.

View Menu The View menu enables you to navigate through a model and to manage the views that you want to save. Using the View menu, you can save and recall named views of a model or follow a line in a model. Also, you can place constraints on the movement of the viewpoint, change between perspective and orthographic transformations of the model, and zoom about the model.

Navigating the Model Understanding the View Cone


B - 77

In the Bentley Navigator, you can view a 3D model through a view that is similar to the lens or viewfinder of a video camera. Instead of moving the model, you seem to move yourself around and to view your model from different viewpoints. The following diagram shows the parts of the view cone.

Near Clipping Plane is the plane parallel to the window that defines the nearest distance that you can see in the model. Objects closer to your viewpoint than the near clipping plane are not visible in the view. Far Clipping Plane is the plane parallel to the window that defines the farthest distance that you can see in the model. Objects beyond the far clipping plane are not visible in the view. Opening files Each time that you open a file, you can access graphic objects, their related data, and the attached reference or auxiliary files. When you open a file, one or more windows are created. The title bar of each window displays the name of the file. If more than one window is open, the file name is followed by Window N, where N is a number between 1 and 16 or PLAN or ELEVATION. Because the Bentley Navigator has a multi-document interface, you can open several models simultaneously in a given session. Each model can have one or more windows open for it with the name of the file displayed in each window. You can move, resize, minimize, maximize, and close each window.


B - 78

To open file

1. From the Windows Start menu, choose Programs > Bentley Navigator 2004 Edition > Bentley Navigator.

2. From the Bentley Navigator menu bar, choose File > Open. The Open JSpace Object Model dialog box, which is a standard file selection dialog box, displays.

The Navigation toolbar contains tools to control and change the mouse modes, view selections, zoom and display options, view locks and view standards. Navigating with the Mouse Viewing the model through the window is similar to using a video camera. Instead of rotating your model to view the other side, you move yourself around to the other side of the model. When you turn your head to the left, the model seems to move to the right. Using the mouse, you can change your viewpoint and navigate through the model to see different parts of the model. When you select a navigational command to place yourself in a particular mode of operation, the cursor shape changes to reflect your current mode. Walking The Walk mode enables you to move in, out, left, and right through the model in one continuous motion without changing controls. While in Walk mode, you can also perform Change Orientation and Pan commands without selecting the commands from the Bentley Navigator menu bar or the Navigation toolbar.

Zooming about the Model The following Zoom commands enable you to move closer to or farther away from the model. Zoom In The Zoom In command enables you to move closer to the model. When you zoom in, you can see a smaller portion of the model in greater detail. In the perspective mode, the Zoom In command moves the viewpoint closer to the model while maintaining a constant perspective angle. In the orthographic mode, the Zoom In command reduces the extent of the view in the window without moving the viewpoint. Zoom Out The Zoom Out command enables you to move farther away from the model. When you zoom out, you see more of the model in less detail. Zoom Object The Zoom Object command enables you to place the viewcenter of your view at the center of one or more selected objects in the model and then moves your viewpoint closer to the object. However, if the selected object is too large to fit in your view, your viewpoint moves away from the object so that you can see the entire object.
