I will try and explain this the best way I can.
I have the letter "T", and I want to print a white letter T and have a red letter T inlaid inside of that. How can I make the inlay smaller, without "scaling" it? Scaling it will make it smaller, but then it wont line up. I need to take say 2 mm off of the outside dimension of the letter. The white letter would have a 2 mm wall around the void on top, then I can print a red T to fit inside that void.
So my question in a nut shell is this. How can I make clearance with out using scale or change the dimensions? I realize the dimensions will change removing the 2 mm, but that is different than changing the x and y dimensions, because that will change the whole letter. I just want to take off 2 mm off the outside.
I cant find info, or at least I cant word my questions right to find what I am looking for.
