System Variables
PLINECONVERTMODE
Specifies the fit method used in converting splines to polylines.
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
If you specify the same value for both the base radius and the top radius, then
a cylindrical helix is created. By default, the top radius is set to the same value
as the base radius. You cannot specify 0 for both the base radius and top radius.
