I have a simple detail view in my drawing. I insert dimensions and centermarks as shown in the picture below and save the drawing file.

However, when I open up the file again all of the dimensions have changed position and the detail view looks messy (picture below). It's almost as all dimensions and centermarks is mirrored. The dimension extension lines snap to other entities than I did when inserting the dimensions (most obvious is the hole diameter).

I have tried to use the setting "Exclude from automatic update", but that doesen't work.

This also sometimes occur when I do a change in the model (.sldasm) and switch back to the drawing (.slddrw)
