.dwg when imported in SketchUp Pro (latest version) has weird jaggered lines which i have never come across before. Can’t really do anything with it. Any ideas?
This is the file:

The geometry is located at a huge distance from the model origin. Select the components and move them to the origin.
The geometry covers such a vast area in the model space that it isn’t visible when Zoom Extents is used to zoom into the top level component.
It’s even worse if you have Preserve Drawing Origin selected. I don’t know what units your drawing is supposed to be in so I imported with units set to Meters.
I removed the symbol keey component because most of it isn’t usable as is and I moved the remaining part close to the origin. I also scaled it down to millimeters.Just guessing at what the units should be based on the objects in the model.
Thank you, I didn’t select Preserve Drawing Origin and chose mm as units. I cleared it up a bit and moved to main axis but it still looks weird and not workable.

Yes, thank you, did the same, but result is still not ok.
Are you still using SketchUp 2023 as your forum profile shows?
This is what I see after setting Profiles to 1.

The component definition needs to be scaled.
No, I’m using latest - 2026 SU. Scale definition didn’t change anything.
Update your forum profile.
It wouldn’t change the appearance of the model but it still needs to be done.
There is a little weird geometry such as on the seats of the toilets. You should only use this import as a reference for creating your own, clean geometry so things like the jaggy edges on the toilet seats won’t really cause any problems.
You would get cleaner geometry from the .dwg if the .dwg wasn’t created so far from the origin.
By the way, you also need to fix incorrect tag usage. ALL edges and faces should be untagged.

I have now exported it as .dwg and imported this back into SU and jaggered lines have been corrected however it still looks messy with geometry on top of other geometry.
I expect that’s the way the geometry was created. Probaby things on different layers in the CAD program.
Seems like there’s a lot of garbage linework in the dwg file.
Yes, it looks like it. I just didn’t expect the file of this quality to come from THE architect. I thought maybe I’m doing something wrong. I’m glad we came to the same conclusion. Thank you for your help!

It seems like its fairly common to see rather sloppy geometry in .dwg and .dxf files. I don’t know exactly why that is. That’s one reason for the general advice to use the imported CAD linework as a reference for creating your own clean geometry. Once the CAD import has served its purpose, delete it and purge the unused components.

In that case I consider myself very lucky to come across file this bad in 4 years of working
