I think what you want is like a variable pitch helix. The curve of the helix begins from a horizontal plane then begins the helix and at the top the pitch transitions to another horizontal plane. In Sketchup you'd have to mess with the line segments. I tried finding something in Blender and haven't found anything. I'm still a novice with that. It looks like Solidworks and Rhino can do something like that.
@L-i-am I tried that a few weeks ago. Its rather hard to get to grips with and feels last-gen in terms of output.
Huge levels of customisation available and a really clever LOD switch.
Hi Guys, I have as seems to be the norm with me, I let the image sit for a day or 2 and let it sit. I think it is because I get tired or whatever. When I pick it up again I can see what needs to be done. I think this image is far superior to the first one'[image: 1722314968829-image11_000-resized.jpg]
