Is there any clear, consolidated place that explains Sweep rules? How do I know if a spine is too curvy? In practice, I’m trying to make this Daft Punk helmet model in a similar process as the bike helmet tutorial. But I want to sweep the front overhead shape of it, versus revolve. I tried sweepin…

Unfortunately there is no way to tell without trying. This is a typical prblem in every CAD system, and it’s really hard to give any meaningful error feedback on this.

Can you please help further? Pretend I have no idea what causes these errors and therefore no idea how to move forward. Is Sweep just useless? Also, please let me know if there’s another way you would try to construct the helmet in my question. It doesn’t have radial symmetry, so that’s why I trie…

i would probably approach this with the loft tool instead of sweeping. In your case, the inner surfaces (the ones generated by the line) most likely causing the sef intersection, based on the screenshot you posted.

Okay I’ll give Loft a try but I don’t think it’s right here. Maybe I’ll see something else when I try again. As before, as a beginner user it would be a great help—and make me interested in continuing to use/buy Shapr3D—if you could lay out the rules for Sweep. I don’t know what angles work or don…

Is there a way to distort an object by controlling Scale only on selected axes? Or another way? While I’d like to learn about Sweep, I might have a work-around for this model by Revolving the side perspective (pictured) 90 degrees twice, and then crushing the sides in so the object is taller than i…

I have done hundreds of sweeps without difficulty. Experimentation, starting simple, will give you the confidence you seem to lack. A better approach than reading some possibly limiting guidelines. Best, Tommy

Same question.

I have the same problem with a rounded spine, though when I tried with two sharply intersecting spine it mostly worked.
