Modifying the Layout of Flexible Duct
You can modify the layout of a flexible duct run drawn using the spline segment mode by moving, adding,
or deleting vertices through the Flex Duct Modify command. A vertex is the location where spline segments
meet. Use this procedure to modify the vertices of a flexible duct run drawn using the spline segment mode.
NOTE If you drew a flexible duct run using the line or arc segment mode, you can modify the layout with the
AutoCAD

1 Select the spline flex duct.
2 Click Duct Flex tab

4 Press Enter on the command line to Enter the desired vertex editing option from the command
line.
If you enter n (Next) or p (Previous) to switch between the vertices in the spline to select the
vertex to modify, the active vertex switches to the next or previous vertex in the direction that
the flex duct was drawn. Depending on the location of the active vertex, one or both of the
options may be available.
5 Edit the vertex layout on the command line as follows:
then… If you want to…
Enter t (Tangent) and then specify a start tangent.
Start or end vertex must be active for this option
to be visible.
change the tangent of the start or end segment
Enter c (Connect) and select a part to which to
connect. Start or end vertex must be active for this
option to be visible.
connect a flex part to another part
Enter m (Move), and then drag the vertex to the
new position.
move a vertex
Enter r (Remove). remove a vertex
Enter i (Insert). Click to specify the insertion point
of the new vertex.
insert a new vertex
Enter g (Regen). update the view based on your changes
Enter x (Exit). exit the vertex mode
