Using Inkscape and wanting to proportionately resize a grouped object based on an included part of the object.
For example I have an image with an outline of something. Within that image is a simple square of some random size. I want to expand the image proportionately until that square is exactly 1"x1" (or whatever)
Presently, I draw a 1"x1" square then select the original object, lock the width and height, and corner drag it until that square looks like it matches my 1x1 square. Then I have to move it to get closer to overlay, and stretch again. Repeat until it looks as close as I can visually manage.
There must be an easier and more efficient way. Suggestions?
