This instructable is to explain how to go from something you made a drawing off on Autodesk Inventor to CorelDRAW so you can laser cut it. I found the first time I did this, it was not at all straight forward. I still have not found a file format that will go straight from Inventor to CorelDRAW without an intermediate program.
Create a drawing in Autodesk Inventor. Make the paper size the same size as the material you will be cutting from. In this case, it is 24x4 inches. Delete the border and title box Inventor puts on the drawing by default.
