Twisted Strip 2.3dm (3.3 MB)

Create closed curve in 2D

Move control points to expand curve to 3D

Create initial cross section normal to the the curve

Sweep1 using the 3D curve and initial cross section to obtain an initial surface

ExtractIsocurve to extract additional cross sections

*The initial surface is only used as the source of the additional cross sections.*

Line Tangent Point OnCurve for line segments tangent to curve at each cross section

*These line segments will be used as the rotation axis for the cross sections*

Rotate3D the cross sections as desired

Sweep1 using the 3D curve and the cross sections

*Closed sweep. If Sweep1 fails because the cross sections cannot be ordered then manually select the individual cross section curves in the appropriate order.*
