1) Select all the objects
2) Right-click on one of them and select "Unions" - "Create union from selected objects"
3) Right-click again and select "Unions" - "Resize Union" and select one of the objects so handles appear on each corner of the union
4) Drag the handles to resize the entire union
5) Right-click and select "Unions" - "Break objects from union" and remove all objects from the union.
6) Pay me $100
Worked beautifully!! Except step 6... that function is not supported in Summer '09!
I had a feeling it had to do with unions, but I never saw the "resize union" option. I tried searching all sorts of keywords including "resize" in Altium's wiki, but it never pulled up the "resize unions" function. Darn them! Anyway thanks a lot!
P.S. We have several drawing templates that we use at our company, but I was making a drawing for a very small, detailed PCB, and our standard smallest template was still way too large. I thought about the DXF import/export option, but I knew the resize option was possible since I saw it done in the past.
Anyway, problem solved. Thanks again Psi!
