Route Duct Lines

Model the duct line by drafting the route.

• Add a line by defining the route of the duct's centerline by clicking specific points.
• A curved duct is automatically added to locations where the direction changes.
• Model the line close to the actual dimensions. Modify the dimensions with the dimension table. Refine the lengths of the straight sections and their relative positions using geometric constraints.

Add the duct line

1. Do either of the following:
   • On the tab, in the Duct group, select Add Duct Line.
   • Select the context-sensitive function Add> Duct Line.
2. On the tab, in the Properties group, select duct line properties. Select a value in the fields Class, Nominal size, Wall Thickness, Item and Curve Item.
3. Select Confirm.
4. Define the sweep plane in one of the following ways:
   • Select the sweep plane with a context-sensitive function, for example Horizontal(XY) Plane.
   • Sweep Plane Based on a Line
   • Sweep Plane Based on a Planar Face
   • Sweep Plane Based on Three Points
5. Define the sweep direction in one of the following ways:
   • Constrain the cursor into a ruler.
   • Planar Face Normal as a Sweep Direction
   • Line as a Sweep Direction
6. Do either of the following:
   • Use the keyboard to enter the position for the next corner point.
   • Before clicking a point you can snap the cursor into a Point, Line or Face on the model if the Snap function is active.
     

     To a Point, Line or Face when the Snap function is active.
     

7. Indicate the corner or end point. Continue modeling the line by clicking the next point.
8. You can undo the line to the previous point by pressing Ctrl+Z and then click a different point.

   You can undo the added points of the same line all the way back to the starting point.

9. When routing the line you can add a component by pressing the B key. Continue routing and accept the component position by selecting Confirm.
10. Select Confirm.
