Greetings all, new to the board.
I have never used a CAD program, but was looking for one so I can modify a simple drawing and came upon DoubleCAD.
I build model planes, and I have a vector PDF drawing of a fuselage that is done to scale, I opened the file in FOXit pdf creator and their measurement tool confirmed the dimensions were correct (there is a 1" reference line). What I want to do is take a very simple drawing for a fuselage, and make some minor modifications to it, then use the drawing so I can use a laser cutter (someone I know has access to one) to cut out the new design.
I converted the file from pdf to dwg with an online converter, opened the file in DoubleCAD and managed to make the changes I wanted, which was lengthen the bottom line, change an angle and raise the motor mount etc. Then I checked the dimensions with the Tools-Inquiry-Distance tool, and the one inch reference point on the drawing shows up as 25.4 inches. How do I change this so that when I measure the 1 inch reference line it shows the correct distance?
