Limitations? specifications? settings? crashes?

Sketchup 2021

In a project of 4000 m² of ground floor and another on the upper part. I have suffered from slowdowns and crashes when trying to merge the two files into one to render.

The final file has the following information:
109 million edges
42 million faces
60 thousand instances of components
21 thousand guides
82 thousand groups

What are Sketchup’s limitations when working with large files?
What are the software’s limitations?
How far does Sketchup go?

Your computer is fine - no problem there.

But you are definiely approaching the limits of SketchUp with this model.

The two things that will keep your model functional, in this case, are:

  1. Reduce the amount of geomerty visible and active on the screen at one time: use Tags to hide things and use Groups to combine edges and allow you to focus on editing the things that you need to edit while hiding the rest of the model. You can’t expect to have everything “active” at once.

  2. Reduce the number of unique Groups and Components - try to explode as much as possible.

  3. Turn off “Profile” edges.

What do you mean by “combine into one render” ?

Is this 3d model generated from Revit? It seem to have a similar structure. I’m curious about that. There are too many edges for this to be a good SketchUp model.
If it includes pipework, then each pipe is going to have a lot of edges - this needs to be simplified if possible.

Any time you import one format of 3d file into another format, there is a lot of inefficiency created by that process. It’s never going to be equal.

If you would like to upload your model I can test it and see if it crashes on my computer.
