Was going to say as well: these should all be in the same "document", and the plates that share the same holes should either be configurations of the same part of parts created in the same part studio!

"Copy workspace" is going to be a very inefficient way to do this but if you wanted to make it work, inserting parts from a different document requires creating a version so I am guessing you didn't do that after the "copy workspace" and making the changes (so you are only able to insert the part as it was immediately after the "copy workspace" operation.

The blocks also look very similar and could likely just be configurations of a single part…

A bit overkill for the "level" of your project but this is a good one to watch for project organization, especially if you plan on doing more complex thins in Onshape:

I'm temporarily working on my old lap top which is slow compared to the desk top. When I first opened your document it took a while but after that it sped up . There does seem to be a lot of detail. If you can remove some of the detail I think it will get notably faster. Like the filleted corners in the rail hole corners. I don't know what gear generator you used but they seem to be a major slow down. If you can make configured parts you may want to use design/reduced configurations. When you're are ready to print or make drawings or calculate mass. Then replace the simplified parts with design parts. Simplified gears don't even need all the teeth but they will continue to function normally. The number of mate connecters seems to be excessive. I left a sample of making a mate with out the connecters. For speed I also suppressed the linear arrays. These can be hidden to speed things up while not working on them.

The other thing to look at would be your computer and network speed. If the video card is lacking there is not much to do except replace if you can. My old lap top wouldn't take any kind of useful video card replacement which is why I switched. too bad since the rest of it is still a good machine. There is a native tool to find what's gobbling up resources. If the net work connection is slow check with the system admin.

I was going to animate but there were no animatable mates. like revolute or slider or gear mates. Check to see if the document work space is up to the latest.

I have a large technical drawings pack in onshape and I have realised there is a mistake in the titleblock. Is there a way to edit the title block and have it apply over the whole document similar to 'edit sheet format' in Solidworks, rather than having to edit each sheet individually? In my opinion, elements on the title block layer should remain consistent across the whole document, so any changes transfer to all sheets.

Thanks,
