Considerations

The purpose of this section is to introduce you to the Design Line interface.

Examples will be kept simple and brief to facilitate the foundational understanding of Design Line and itscomponents required for advanced Design Line features.

Examples in this document assume you are using the TSI default, imperial, configuration.

Design L ine in the Collective Environment

Design Line Setup and Use can affect applications connected to the same database. Consider Design Linebehavior from the perspective of each discipline. Estimators, Designers, Draftsmen, and Fabricators can benefitfrom the use of Design Line.

Introduction to Design Line Interface in CAD-Duct and CAD-Mech

1. An additional fly-out menu has been added to the CAD-Duct / CAD-Mech toolbar.a. The CAD-Duct Design Tools toolbar is the third button from the (Bottom/Right) side of the toolbar.

b. Additional tools include:i. Flow/Size Calculator

Use the Flow Calculator to determine duct sizes based on Velocity, Flow Rate, PressureDrop, and Aspect Ratio. The Flow Calculator dialog remains active until closed by theuser. (Note: Settings used last are stored in Design.ini)

i. Design SizeThe Ductulator provides similar, more limited, functionality as the Flow Calculator. Futurereleases will not likely include this option.

ii. New Design LineThis command starts a new Design Line in the drawing.

iii. Edit Design LineUse this command to edit Design Line segments..

iv. Manage Constraints (resize)Constraints may be edited after Design Line segments have been created.

v. Erase 3D DesignThis command will erase all 3D objects associated with the selected Design Line.

g. DeleteDelete individual segments of a Design Line.

17


18/56

Node Options

1. Node options include:

a. Define SourceUse this command to change the source of a Design Line. The Source of a Design Lineis used in conjunction with the service flow direction to determine proper fittingplacement.

b. TerminalsSelect Terminals to change terminal height, assign flow, or define terminal directions.

c. FillUse the Fill option to draw 3D components associated with design nodes. This is useful ifyou only want to see 3D graphics for design nodes (terminals).

d. DeleteUse the Delete option to remove segments from the design line.

View Options

1. View options include:

a. AnnotateToggle Design Line annotations on and off using this option.

b. CalculateCalculate causes the Design Line to "re-evaluate" the solution for current parameters.This option may be more necessary depending on which constraints are used.(Example: Systems constrained by pressure drop rely on calculations to determineterminal velocities.)(Note: It is also be necessary to “Calculate” one time before node annotations are

displayed / changed.)c. Fill in 3DFill in 3D applies components from the current service to the active Design Line segment.Fill in 3D causes the Design Line to calculate.

d. Fill Auto HangersUse Fill Auto Hangers to apply hangers to a Design Line, without redrawing fittings andstraights. This feature is particularly useful with Revdesign. (Note: Remember Fill in 3Dredraws everything on the Design Line. Fill Auto Hangers only redraws hangers.)

e. Calculate Pressure DropUse the Calculate Drop dialog to show the breakdown of a Design Line by sections andcircuits. Calculate the maximum pressure drop of the Index Run to size equipment.

f. Resize

18


19/56

This Option has been replaced and will be discontinued.

3. Restriction Prompts

x. Previous versions of Design Line included Restriction Prompts. This feature is renamed“Design Entry”. You will be prompted to enter the desired size for each Design Linesegment.

xi. You may also choose to be prompted for constraint values as they applied to the currentservice.

4. ElevationThe elevation specified is maintained for the current Design Line Segment.

5. CeilingThe ceiling height specified is applied to terminal objects. (For example: A ceiling height of 8’-0”would automatically place diffusers at that elevation, and calculate drops as related to main orbranch runs.)

21


22/56

6. Fix By

This new option represents a cross-section of the routed shape. Users specify the desiredrelationship between the Design Line and components applied to it.

Selecting the Bottom Middle option will cause design line to insure that

components are oriented “Flat On Bottom”.

By default the “Fix by” option is set to centerline.

22


23/56

7. Offset

Use Offset to specify an offset elevation while routing Design Lines.a. Offset will be grayed out if the Elevation option is not used.b. Type in the positive or negative distance (change in elevation) and continue selecting

points.

8. Add RiserUse the Add Riser button to view change in direction graphics immediately.

a. While routing a Design Line, change the Elevation value and left click the Add Riserbutton. (Note: The riser will be added if you do not click the Add Riser button. You will notsee the riser graphics until you right click to end the Design Line segment.)

Basic Design Line Usage

CAD-Duct

This example uses the SA LP service from the default, imperial, TSI configuration. The constraints defined in thisservice are based on Velocity.

Because velocity is the only constraint applied to the service, users are prompted to select constraints with pre-defined velocity. Design Line uses information in the database, combined with preferred velocity values, and

terminal requirements to size ductwork.

1. Open a blank drawing.a. Make sure your limits will allow you to draw in an area of at least three hundred feet square.b. Zoom Extents.

2. Select the SA LP service from the service and section toolbar.3. Select “New Design Line” button from the fly-out menu.
