Why is my DXF file the wrong size?
Check units and reference dimensions before reusing a drawing.
First check the units in the source and destination systems and a known distance. Millimetres and inches differ by a factor of 25.4. One matching dimension alone does not confirm all geometry information.
- 01100 mm
- 023.937 inches
- 03100 mm
3.937 inches is rounded. Use the exact factor 25.4 for conversion.
Common mistake
Resizing the drawing visually without identifying the cause.
What to check next
- Keep the original file unchanged.
- Set units explicitly and check two independent distances.
- Compare line types and notches after exporting again.
Practical foundation; not instructions for a verified CutCortex command.
