I had this issue for a while, did not manage to reach any help from Sketup support.
Device:
MacOS
Big Sur 11.1
Processor 2.7 GHz Quad-core Intel Core i7
Graphics Radeon Pro 455 2 GB
Sketchup Pro 21.0.392
Problem: The navigation is very slow, it keeps freezing, the loading wheel on the mouse pops up every few minutes and It’s almost impossible to work with more complex components.
I reinstalled my entire laptop, updated the OS and it feels like it’s even worse than it was before.
What is a “simple model” in your definition? How many edges and faces, how many components and groups? Can you post a .SKP model file, or a screen-shot of one?
If the current scene has Profiles and/or Shadows turned on, try turning them off. This generally speeds up the rendering of the SketchUp viewport considerably.
There are a number of components that appear to have come from the 3D Warehouse that could be reduced. when using components you are downloading from the Warehouse you should download them into a separate file to check and clean them before putting them into your model.
The model is massively overloaded with very heavy entourage elements, probably from the 3D warehouse. The worst offender is the set of 12 chairs (Cadeira Husk B&B…) which together contribute 1,819,584 edges. Next worst is Group#321 (looks like a mixer) which has 325,528 edges. Then the bicycle, with 279,170 edges.
I could keep going, but that’s enough to show the issue. These imported models are way too detailed and are bringing your computer to its knees. You should at minimum give them a tag that you can turn off, or better, replace them with simpler proxies until you are finished developing your model, have final scenes set up, and ready to render.
On another note, if you switch to monochrome mode you will see that a large proportion of your faces are reversed, showing gray-blue back side color instead of white. You should correct their orientation before applying materials, as materials will mask this situation, but many renderers will show only the front sides of faces.
In addition to what the others said, the spinning cursor does happen while auto save is going on. You could go into Preferences, General, and set that to be less frequent. It’s odd that the cursor kicks in, and I will ask colleagues to take a look to see what it is about the model that makes it so hard to save.
Between auto saves you could make the smoothness of working on the model be a lot better. Go to View, Edge Style, and uncheck Profiles. You will be shocked at how much smoother it becomes.
Here’s a sofa for you to try. It’s the one you are using, but reduced to 1/3rd of the number of edges and faces.
Hello there, I am having this issue as well. I do make complex interiors which i am sure have too many edges etc. Can someone please post how to control the 3d warehouse downloads in model and turn them on and off or to control edges and faces. Best protocol for quick modelling in sketchup to not slow down computer unnecessarily.
You can give the components tags and then turn off visibility for tags you don’t need to see while you are working.
Before you add the components to your project file, though, you should download them into a separate file where you can examine them to make sure they are suitable for your model. In the 3D Warehouse you can filter for file size and polygon count.
Once you have the model downloaded into your separate file, look to see what you can do to reduce them even further. Look for details that would never show in your project file. Knobs on ovens and ranges probably don’t need labels or numbers around them. There’s probably no need for interiors in ovens, refrigerators or shelves in closed cabinets. A couch doesn’t need a bottom surface. If you are showing a bed that looks like it has been made, there’s no need for mattress and box spring. The duvet will hold its shape just fine without a mattress under it. Be brutal and strip out everything that isn’t needed to communicate your idea.
Purge your files often to get rid of unused stuff. If you look up at my screen shots from working on the OP’s SketchUp file you can see there were a lot of components in the file. About 1/3 of them were not being used along with about half the materials. Purging the unused stuff cut the file size to less than half.
There’s more that can be done but that will give you a good start.
By the way, after cleaning up components you’ve gotten from the 3D Warehouse save them either as a local components collection or in your own private collection in the 3D Warehouse so you can use them again in future projects.
