Edit: This may be a graphic card driver issue.
Unfortunately my system and card are no longer supported by SW... so I don't know how to fix it.
They were fine for SW15-17, but now don't even show up in the list.
What do you do when SW stops supporting your configuration suddenly?
So I both like and dislike the way the dimensions display now in sketches in SW2018.
I sort of like that you now know whether or not you are facing the "proper" normal because the numbers are backwards if not.
I sort of dislike this because now I can't read my dimensions...
Also I did not find this in the What'sNew2018 PDF... kinda worth mentioning, no? Or is my SW just bugging?
