I’m currently working in Rhino for Mac but have access to Rhino 5 for Windows as well.
I’m working with double curved panels that fit into a larger frame. For this reason, the edge can’t move as I manipulate the surface. I want the middle of the surface to bulge out (like a cushion, or pocket of fluid). I have tried rebuilding and manipulating the number of control points. Either the edge moves or I can’t get a smooth bulge in the middle. I’ve also tried in Maya with sculpting and soft selection, but the edge moves there as well. Any ideas?
I uploaded a photo of one of the panels. They were originally trimmed from a torus, which is why the control points are this way. I’ve already shrunk the surface.
I think what you want isnt possible by transforming this surface.
The edges will ALWAYS move. You need to recreate the surface for doing what you want.
I was wondering if that might be the case…I’m currently attempting to create a new surface with NetworkSrf, no luck so far. If you know of a better alternative, suggestions are welcome. Thanks again!
You could try to offset the surface and trim it to be the size the top of the cushion would be. Cut a hole in the original surface that is bigger than the offset surface (probably just the edge of the original surface offset a small amount inwards). Then blend the two surfaces.
