One small complaint I have with Solidworks Sketching has to do with the Smart Dimension tool.
Here is an example.
Say I sketch out a rectangle with Sides A and B. No dimensions are set. I open dimension tool and click side A which is let's say 9" before dimensioning and give it a dimension of 8". Then I click side B which pops up the smart dimension box and it shows 3". Then I decide I don't want to give it a dimension after all. If I have clicked to open the dimension dialogue box even hitting escape or red X does not cancel dimension. It simply places the current value as a dimension in this case 3". Then if I hit UNDO, it will delete dimension but ALSO reverts my 8" dimension back to 9" also!
This is a real annoyance if I click on a line by mistake. Then I have to go back and delete the dimension first before dimensioning what I want.
Is there a slicker way to cancel/undo a dimension that is clicked on by mistake?
