I’m trying to simulate a shape similar to (but not the same as!) the attached picture of a chimney cowl.
Basically I’m aiming to cut spiral lines in a flat surface and then press or pull the centre along the Z axis to form the helix type shape.
My current rather poor attempt is attached. I’m well out of my depth here - the surface is not cut and doesn’t follow the lines, the top doesn’t rotate, etc.
Any help or pointers would be great…
