I have just spent my lunch hour exploring the scene files. Thank you so much, it’s really opened my eyes to looking at things differently. I haven’t looked at the tracer function yet as I’ve been looking at so many other areas, so good to see how this can be used.
To further explore and model the first scene you sent, I added an n-gon sweep to the 8 sphere/1234 rotation spline and it caused a strange clipping at the top point (see left object in scene file below “Clipped Top” in Object Manager). However I do not see this glitch on the 7 sphere/1080 rotation version. Thought you might like to know about the clipping if it may be caused by something else or is expected.
The next step I wanted to do was convert the heptagon spline to a polygon object. So I tried with both the Loft and Extrude effect and they both cause another strange effect as shown on the right hand object in the scene file below.
Any pointers much appreciated.
