Very slow 2nd dwg import

sketchup pro 2018 BUG

When I import a dwg from rhino or revit in sketchup it imports fine and takes an instant to import. When I re-import an updated version of the dwg in the same sketchup file it takes forever, sometimes 15 minutes, sometimes more (hours).

Does this happen to you guys also? Is there a solution for this? Like maybe importing the updated dwg file in an empty sketchup file and then batch-changing all the names of the components or layers?
I don't know if it would change anything but I suspect it comes from the fact that it's the same component that gets re-imported.

Any help would be appreciated!

It wouldn't surprise me if there component names that need to be dealt with because they are the same in each of the imports. I doubt that makes it a bug. In any case, if the DWG file has been updated, that would imply that the old one is no longer correct. I would remove the old components, including purging of unused before importing the updated DWG. Or I would import the updated DWG into a separate file and then copy only those new/updated components to the existing file after purging it.

The problem is that I want to have the old version also in my file. I hope someone found a workaround for this and is willing to share as some of my projects are quite large and really take a huge amount of time to import, sometimes I even have to stop it because it freezes SketchUp completely for a couple of hours.

For now I import it in another file and then import it piece by piece but this is very time-intensive..

You can't have two different component definitions with the same definition name so maybe renaming the first ones would make sense. Perhaps there's an extension that would allow you to rename components en masse by adding a prefix or suffix to the definition name.

There is nz_EasyGroups, but it's not free. IIRC there are some free options as well.

Thanks! I'll try that to see if it helps
