Im trying to edit a part in an assembly, section view is on if that makes any difference. I am unable to select a dimension to delete or move it, I can only change the value. Dynamic highlighting is on. I have never experienced this before, only noticed it recently. I havent updated since installing on this machine so that shouldn't have anything to do with it. If i open the part and edit the sketch, no problem at all I can select it all day long.
Im on 2016 SP0.1
This is really starting to drive me mad, any ideas?
If this is your issue, it may be the Instant2D function found in the Sketch tab. Every time I would go to delete a dimension in would bring up a small text field to change the dimension value. It was driving me crazy because it just started happening to me all of a sudden. Dan mentioned the Instant3d which didn't help me, but I noticed the Instant2d and tried turning that off. That took care of it for me. Below is a shot of clicking on a dimension with and without Instant2d.
