Currently when I am drafting a part in Solidworks it always removes material. Is there a way to set it up so it adds material.

For example if you have a cube that is 3" wide and you draft one side, that side at it's narrowest point will be less then 3". If you add draft then the narrowest point will be 3".

I have a machined print that I am creating the model and when I add draft my overall part at the narrowest point is too small.

Any ideas?
