Sometimes when I'm working on a drawing, I pull a similar one up next to it as a guide. But now when I switch between drawings, SW has to rebuild (maybe?) the drawing when I click on it even though nothing in the drawing or parts have changed since I clicked off of it... this happens with assemblies as well.
I only noticed today what SW's explanation of this might be because my machine was going slow and I saw a window pop up for a second that said "Components have been modified, updating assembly..."
No components had been modified. Is this a setting that I can turn off? Some kind of superfluous error checking or make-sure-assy/dwg-is-up-to-date thing? It's awfully inconvenient.
