I have a surface and I want its corners to extend like this. How do I create and attach this?
Untitled.3dm (859.2 KB)
Several approaches:
a) Extend the existing surface and trim to the desired shape. I would:
DupBorder the existing surface. Use a new layer with a different color.
Untrim the existing surface.
ExtendSrf the existing surface beyond the desired corner.
Pull the corner curves onto the extended surface, using the new layer.
Trim the border curve with the pulled curves.
Trim the extended surface with the revised border curve.
(Optional) Shrink the extended surface.
b) Create a surface using the curves and the edge of the existing surface. I would:
SplitEdge the edge of the existing surface at the upper curve
Sweep2 with the curves as the rails and the edge as the section.
MatchSrf could be used to make the flow between the new and original surface smoother, but it would pull the new surface away from the existing surface because the upper curve is not tangent to the existing surface.
Join to create a polysurface.
c) Create a new surface which includes the pointed corner.
many thanks for your help. can you share the file please?
I did not save the file. You should be able to replicate it. Try it. If you have difficulties or specifc questions post a description of the problem or specific question. And it’s always good to include a .3dm file with what you have tried.
