Edges on Polysurfaces

[blackbanjo]

Hello, I am wondering how to work with the edges in polysurfaces. Oftentimes I make a poly surface (say, a box) and I work with it and modify it until it fits for my purpose. After I have stretched it, moved its faces, trimmed it, merged with other boxes....after all this it has a ton of edges that are entirely unnecessary.

 

Is there a way to ask Rhino to rebuild the object and eliminate unnecessary edges?

 

I attached a small example of a simple object that has tons of leftover edges after I worked with it.

Stay away from stretching - it generates a lot of edges! Modeling smart in Rhino is an advanced topic - everithing starts with a curve and how many points are here! Seems You are modeling like with solids - model with surfaces, joining, blending and trimming them.

No matter what I do, I will always need to modify some polysurface or surface. Anything I do to modify them causes edges. There should be a way to rebuild the surface/polysurface and remove unnecessary edges.

Yes, there is. But the way You ask shows that You are not quite deep into working with nurbs. How You don't know this tools in Rhino:? -

I can't claim to be an expert, but "Rebuild" does not work on polysurfaces as far as I know. I will experiment and let you know what I come up with.

Try the MergeFace command, with MergeAllCoplanar=Yes.
