So I need to model a spiral that will unravel in a different different direction at one end. Turns out this is a huge pain in the ass - especially since the spiral shaft is not perfectly round, but instead a semicircle. Get the picture?
Had it been a simple spiral I’d have used the screw modifier and been done with it ages ago.
Spent all day on it yesterday and while I’ve learned some new things in the process I have no answers yet.
I tried using a curve and modelling along the curve path with the Bevel & Taper method.
There are two problems with this though. I can’t get a spiral as perfectly shaped as the ones the Screw modifier generates. But most importantly I can’t control the direction in which the semicircle pivots along the curve path.
Now I just need to figure out how to make a bézier curve in the shape of a perfect spiral.
Have you tried the Mesh-to-Curve option (Alt-C)? You could probably use the spin/screw tools to make a mesh spiral then convert to curve. I think it only works on single-vertex wide paths.
Thanks for the idea!
I tested this, but the curve that is generated is not bézier (there are no handles), it is just a regular curve.
I hit the V key with all verts selected and tried to change the type, but nothing changes. Why might this be?
I went to to the Tool panel. I also tried from the Edit Mode Curve menu. I also tried with the keyboard shortcut. But nothing changes. Here’s a screen shot of my test circle, converted from a mesh to a curve. I can’t seem to get bézier handles to show up no matter what I do. You can see that all verts are selected (in orange), and Handle Type is set to Automatic - yet I still just have rigid lines and points.
Going all poly would make it very difficult nearly impossible to pose and maintain a natural-looking curve. Unless I rig an armature. But then I have to choose between a low bone count resulting in a rigid look, and a high bone count with hard-to-manage IK.
Thank you, Ricky! That was exactly what I needed to know. Bézier curves are working now.
And thanks for the link. Not sure how I missed it the first time.
Cheers!
