Controls the shape of lofted solids and surfaces.
The setting is stored as a bitcode using the sum of the following values:
1
No twist (minimizes the twist between cross sections)
2
Align direction (aligns the start to end direction of each cross section curve)
4
Simplify (produces simple solids and surfaces, such as a cylinder or plane, instead of spline solids and surfaces)
8
Close (closes the surface or solid between the first and the last cross sections)
