I’m struggling on the attempt of obtaining a decent (variable) fillet on edges and vertex of a form which is a icosahedron modified to resemble a stretched elastic fabric. The problem is that the vertex must be finishing with a spherical termination.
I tried some combinations of radiuses but, at the end, the only way is to fillet then cut the solid near the vertex and try to rebuild the termination…but even this way the thing start to be a problem, as I can’t really build a “termination” surface which as a decent continuity, due to the fact that the starting surface (the simil icosahedron one) is a polysurface and, at least to me, it results impossible to make a continuous connection with the added one, without a very long, hard, repetitive work…
The situation on the last image is where I go really mad: I should find a way to connect a multi part border (the on below, on the icosahedron like form) with a single continous border (the one of the little half-sphere on top).
I would hope it was possible something like a single loft operation, but the command doesn’t give me the possibility to correct the edges curvature to match each other…
Actually _Blendsrf is working but it gives me a really ribbed, veined surface. I was asking myself if there’s a way to obtain something smoother or more controllable.
I post here a rough image of the result and the original model…
the reason why you are getting those results is that you are blending between an edge that has continuous curvature and a polyedge that has curvature breaks.
If you create the fillets with BlendEdge you’ll also end up with a smoother BlendSrf result.
What can help getting a smoother BlendSrf result with these complex transitions is RemoveMultiknot on the BlendSrf. I will affect the edge G0 precision, so make sure to check the end result.
Your version is very smooth and it’s exactly what I was searching for: I’ll immediatly try Blendsrf and the procedure you suggest, then I’ll give you feedback here about the results.
In the meantime: thank you very much about your help, Gijs!
