I'm trying to do some 2D sketching in a drawing. I've opened a .dwg and imported it. However after I add new entities, I try to Smart Dimension them, I can enter a value and the text changes but the actual sketch does not change. If I go create a new drawing instead of opening the .dwg and importing it. the sketch and dim tools work as expected.
Has this ever happened to anyone before? Any fix?
