Hi 3dalbertsoft - having lots of fun with this plugin!
Is there a way to rotate the extruded shape on its own axis as it follows the curve? That is to say, in your video at 5:00 you extrude a triangle along the curve. What I would like to do is rotate the triangle on its center, perpendicular to the curve, so that I may have a twisting triangular tube. Thanks for the work on this!
