Then more often than not, I lose links to my model in the view port. I ask to open the model in SU in the context menu and the model is still there intact.
How do I restore the link from the yellow triangle of death?
hey.
do you have a studio or a pro licence ?
this is the revit importer for SU/LO that has a problem.
depending on your answer, we can either uninstall or reinstall it.
edit : anyway, it works the same.
redownload sketchup’s installer. right click on it, run as admin, and there, you’ll untick revit importer.
when it’s done, do a clean restart, and try again
(off course, if you want to reinstall it, same way)
I think these are two separate problems.
The extension error is coming from the SketchUp side — LayOut doesn’t load Ruby extensions, and the report header gives it away (SketchUp: 26.2.243, Ruby: 3.2.2). su_revit_importer_installer is one of SketchUp’s own components, and it’s failing on a registry key it expected to find and didn’t. It fails at load time and doesn’t touch your documents, so I don’t think it’s what’s breaking your links.
For the references, Document Setup (Window menu on Windows) → References is the place to look. It separates the two things that look alike from the canvas:
- name highlighted = out of date → Update
- file moved or renamed → Relink
That pane also shows the stored path for each reference, and that’s the bit I’d check first. “Breaks with every new start” points more at the saved path not resolving at launch than at anything wrong with the model — which fits, since the model itself is clearly fine when you open it from the context menu.
Also worth making sure the yellow triangle isn’t a red herring. If References lists the model normally and only the viewport looks stale, that’s a rendering state — select the viewport and hit Render in the SketchUp Model panel, or set it to Auto. If References shows it out of date or can’t resolve it, that’s the link.
What do the paths in that References pane actually look like — a plain local folder, a network or mapped drive, or something like OneDrive/Dropbox? That would narrow it down a lot.
