A Positive Negative?


Negative Dimensions

Did you know that it is now possible to use negative dimensions in a sketch?  If you want to move a feature from one side to the other, you no longer have to delete the dimension, just move the feature to the other side and add the dimension back in.

Negative dims 1

Double click the dimension of the feature you want to move.

Negative dims 2

Type in the negative value of the dimension and watch the feature flip to the opposite side.  Also, the dimension will be displayed correctly and not with a minus sign in front of it.  This was a great little enhancement in 2009 that makes our lives a little easier.

  1. Hi,
    I am not sure I fully understand the behavior you explain.
    For example, when you make the dimension 22 negative, why does the hole flip and not the edge? Obviously, there is some underlying logic which I have not been able to understand.
    Also what would happen if I make the dimension 30 (on the right side below the slot width dimension 20) negative?
    Would it be allowed? If not, why not?
    If yes, what would happen? Which edge would flip? Why that particular edge and not the other one?
