I have a problem with GH when I import (STP File) surface from Creo to Rhino and put it into the formula, the pattern surface area will suddenly be extended. I would like to keep the area the same as the Creo area.
The inner outline is surface in rhino, and the outer outline of pattern surface is the simulation of GH.
I don’t know why the simulated GH surface can’t match my rhino surface.
what you see here is typical behavior for parametric CAD software like ‘Creo’ or ‘Catia’. And it has its purposes…
It’s rather wrong to modify the underlying shape, just because you want to map some pattern on it!
What you should do is to create a surface (or curve net) where you create the pattern on, and then you project the pattern on your shape. If you do it like this, you have more freedom in mapping, you can map onto much more complex shapes (consisting of multiple surfaces) and you don’t need to touch the initial shape at all (no rematching etc.)…
