Plan view of 3D curb polylines with ramp dimensions
3D view of curb polylines and ramp
This command modifies 3D curb polylines to fit in a ramp of the
specified dimensions. For input, this command requires 3 3D
polylines that define the face of curb (bottom and top) and the
back of curb. There is a dialog to enter the curb dimensions. Then
the program prompts to pick a point on the curb 3D polylines to
draw the ramp. This point is used as the center for the ramp. The
existing 3D curb polylines are modified to lower the curb for the
ramp and new 3D polylines are drawn for the rest of the ramp. These
3D polylines can then be used for breaklines in surface modeling
such as with the Triangulate & Contour routine.
