I am reaching out for some help with Rhino. As a new user, I am struggling to create a blister for a plenum. My plan was to place a SubD plane over it to form the blister, but I cannot get the plane to snap to the B-spline as intended.
I suspect I am missing a minor setting or a specific key command during selection. I have already tried the following without success:
I have exhausted ChatGPT and Genimi
Do you have a 3dm file with just the surface or mesh with the cutout/hole that you are trying to model a bump detail over? Use the Export command to save only the selection as it’s own 3dm. I’m not sure what the cross section of the bump detail should be so also include what you have for that geometry too please.
If I’m understanding the issue correctly, you need the edge of the bump detail to match the cutout border. Do you need curvature continuity across that seam as well? Does it have to be a SubD for some reason? Depending on the geometry type with the cutout in it, it may be better, for instance, to model the bump detail as NURBS with NetworkSrf.
As far as I’m aware it’s not possible to match a (smooth) subd object to a curve. You can match the subd box mode, but as soon as you toggle to smooth mode you lose position. Moving vertices in smooth mode disrupts neighboring vertices.
If it’s possible I’d also like to know.
