I am totally new to CAD, I have the free version of Alibre. I am starting with a blank sheet and drawing a 2D thing made up of simple lines, ovals and circles. When done I would like to save my original drawing, but then make some copies at a different size. Isn't there a simple way to highlight everything on the screen and choose to increase the scale by 75% or something? It seems so simple of a task, but 3 days of looking and it don't make sense
