PEDIT
Edits polylines and 3D polygon meshes.
PLINE
Creates a 2D polyline.
SPLINE
Creates a smooth B-spline curve that passes through or near a set of points
that controls the shape of the curve.
SPLINEDIT
Modifies the parameters of a spline or converts a spline-fit polyline to a
spline.
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.
