Why is this very simple model saving so large?

polysurface
rhino
grasshopper
python
rhino5

Rhino_Help.3dm (18.2 MB)

So I wouldn’t have noticed if it was just 20mb with these 4 solids -but my actual model has like 60 of these simple solids and the file size is over 600mb. This happens every time I split many curves out of one surface. I have no idea how that would create such a large file size.

I did save small and I did copy over these pieces from another .3dm model. So I have no idea whats going on here.

Thanks!

Hi Aiden,

Looks like your hexagonal surfaces are a trimmed part of a much larger complex surface. You can see it by exploding the solid and showing one of the top surfaces points. It’s quite heavy and that’s what makes the file big (remembering a complex surface that is underlying your cut pieces). Try shrinking the surface ( _ShrinkTrimmedSrf ). The file size goes down to 345 kB.

PS. Save small would not help here. It only does not save render meshes which are not an issue here.
