I'm rebuilding an OpenROV that a student assembled poorly. I've found that I need to recut a number of pieces and I have not been able to open the DXF file. Is there something special I need to open it? Or any free software that doesn't have issue reading it?
There are some programs that can do the work.
I use, DraftSight, a free cad sofware from Dassault.
Oh Sorry i missed the main issue:
Check the drawing scale once opened with any CAD soft you use. Many of them use default scales that do not match the original ROV plans.
Hence, uncorrect measurements are applied to all pieces.
Fixing that, is as simple as scaling the whole plan.
