Aligning edges of surfaces
Aligning edges of surfaces
(OP)
I opened up a file with surfaces and I need to extend the edges so I can use the surface to cut a solid. I'm assuming the edges have to be perfectly aligned so I can creat some kind of border around the surface. From there I need to extend the edges of the surface past the solid so it will cut. I've attached a power point to illustrate what I'm trying to do. I was able to do it in Catia so I put some pictures of what I did.

Edit - Surface - Boundary
First on a separate layer I'd extract a copy of each surface, then turn off the original surface layer.
Next I'd create another sphere larger than any of the surfaces to be extended.
Edit - Surface - Boundary
Select the first individual surface to extend, and select Replace Edge, at the prompt select the sphere face, then I believe click ok twice. If it's going to work you'll know at this point, because it should have extended the surface and be asking which portion you want to keep. Cursor select the portion to keep and click apply.
I hope I explained that complete enough you can fill in any missed selections.

Once you have extended the remaining surfaces, sew the sheets together. Retrieve your final sphere size and use the trim command.
RE: Aligning edges of surfaces
I did notice that the 4 surfaces are not tangent to each other along the shortest of the 4 adjacent edges - you might be able to use Change Edge to get these to shape up a bit, but you may have to either rebuild them and make them tangent, or use heal, or use Match Edge (if you have the license for Shape Studio).
