File too Heavy

My file is wayyyyy too heavy, Idk why, Idk how to fix it, I need to make it way lighter in order to continue working with it, Idk what I did to make it so heavy but its freezing my laptop. HELPPP PLS!!!.

Each triangle is a polysurface, maybe thats the reason its so heavy, if thats the case how can I make it a clean model?

How do you intend to use these models?

Rescue3dmFile
might allow you to load parts of the file only.

Audit3dmFile
might give a first idea of what is wrong.

you migth also be able to use

SetRedrawOff

and select objects by layer and copy them to new document, save, close,

SetRedrawOn

good luck / kind regards - tom

ok the following should help:

_SetRedrawOff
→ open your file
set the display to wireframe
'_SetDisplayMode _Viewport=_Active _Mode=_Wireframe

_SetRedrawOn

Rhino uses 3.3 GB Ram on my machine when only your file is open - that should be manageable…

does this work for you ?

EDIT:

can you open this file - should be in wireframe - one object per layer, most layers turned of:

The facets appear to be planar, but I did not check them all. Merging the coplanar faces in each facet will help, since Rhino won’t try to mesh each surface within facet for display (there are thousands of surfaces in each facet). Turning the meshing all the way down for the display can also help.

Depending on the intended use, there might be other considerations. Note that some surfaces are meshes, not polysurfaces, so that could be an issue depending on how you intend to modify these.
