I’m getting explanation points showing up in yellow triangles next to some revisions in my Layout documents - can’t find any definition/explanation in “Help” to tell me what these mean or how to fix/get rid of them. Can anyone tell me what they mean and what causes them?
I think you mean exclamation points. They indicate that the reference file is different than the embedded copy and the embedded copy needs to be updated. Typically you’ll see this when the viewports for the SketchUp model need to be updated by rendering and you have Auto render turned off. Tick the box or select the viewports and click on Render.
