When I try to insert a door with Dibac it doesn’t seem to actually connect with my wall. I am also not able to toggle which direction the door swings in? Sketchup at some point will crash. once started up I have to re-authorize my Dibac.
Are you editing the group of the wall? You need to be in the right context.
If you have to reauthorize upon startup, you probably have an issue with read/write permissions. How did you install? Did you drag the SketchUp folder in the application-folder?
You seem to have a very new version that a lot of people are waiting for.
Check SketchUp->About SketchUp to show (18.1 is the latest thus far)
