I am learning AutoCAd and WOW there is so much to learn.

I have made some 2D drawings. I save them as DXF files. I import them into Mach2 to CNC what I drew in AutoCAD. I have to tell Mach2 how deep each line is. Is there a way I can do this in AutoCAD?

I want Z to start at 0 and have it go down to like -3 or -6. This way when I import the DXF file into Mach2 it will then know how deep each line is supposed to be.

Many thanks in advance. :cheers:
