I have used my version of 2018 SketchUp Pro to import dxf/dwg files without trouble for a long time. Sometime a couple months ago dxf/dwg import just stopped working - there is no error message, just nothing happens when I try to import a file. Occasionally after a failed import attempt the shortcuts also stop working, and I need to restart the program to get them back (though changing my mouse settings somewhat helped and this doesn’t happen so often anymore). I have reinstalled the program and it did not help.
I assume this is due to some Windows update, but I was wondering if anyone had similar issues and, if so, what they may have done to address them. The only reason our company paid for Pro was for this feature and we are currently working on a project where I cannot really work around this.
