I may have spoken too soon. When I tried to move forward with my plan, I ran into more trouble.
What I want to do is define a section programmatically, then [sweep? extrude?] the section along a collection of given curves, while maintainting control over the attitude of the section as it travels along the curves. It seems like I am close, but I’m not getting the results I think I should.
Sweep1 File -
- I played around with various combinations of rails, sections, and grafting. I got some to work, but when it came to sweeping one profile around multiple rails, I had only limited success at best.
Sweep44 File -
- I believe I successfully generated the section, and translated it into alignment with the start of each rail. This was tricky because the serial rotation of the perpendicular frame changes with curve geometry.
- I tried to sweep a list of sections around a list of rails, but it doesn’t really work out. Being a beginner, I’m sure there are many things about conditioning the inputs that I do not understand yet.
- In oder to check that my setup was valid, I baked the sections and made copies of all the sections and rails, to try sweeping them individually. Curiously, the copy function changed the locations of the curve seams. Whereas previously I got strange results, after copying I got no results at all.
- After correcting the location of the curve seams by rotaion, I could then perform a sweep with more or less expected results, with one exception: The curve that is inclined to both axes fails.
Any insights as to what I am doing wrong here would be greatly appreciated.
