using the Spline option of the PEDIT command generates only an approximate
spline-fit polyline.

Draw Helixes
A helix is an open 2D or 3D spiral.
You can use a helix as a path with the SWEEP command. For example, you
might sweep a circle along a helix path to create a solid model of a spring.
When you create a helix, you can specify the following:
Base radius
Top radius
Height
Number of turns
Turn height
Twist direction
