I'm working with sheet metal in mm, but when I export the flat pattern in dxf it go to imperial unit and the flatten grow up when I open in solidworks.

 

What can I do?

Can you share an exported DXF here? You'll need to zip it to be able to upload.

 

Thanks Mark

Its been a while i have used Solidworks, I remember Solidworks should have a unit selection while importing a DXF file can you recheck again importing dxf file with mm?

I made the part in mm ( my fusion is configured for mm) and when I opened it was with wrong measures.

Have you tried reimporting the DXF into a sketch in Fusion? From past experience Solidworks doesn't read\write DXF file units correctly that's why I asked if you could share the DXF file here. If the file reimports into Fusion then the file's correct.

Just did a test using ZW3d and it reads the units from an exported DXF flat patter as you can see below. Fusion left ZW3d on the right.

As I said in post #2 you have to ZIP DXF files to be able to upload them.

Opened the file in Zw3d, Fusion, Rhino and Alibre and it open at the correct size and scale so the problem is Solidworks.

 

This has come up before and it's because Solidworks only reads\writes the Measurement parameter in DXF files, it should be reading and writing the INSUNITS parameter. Measurement only sets Imperial or Metric, but metric what? MM, CM, Meters, Kilometres? You need to report the bug to Solidworks and if they say the problem is down to Autodesk remind them Autodesk created the DXF format.

 

Are you sure solidworks doesn't have an override for units on its import dialog? ZW3d and Alibre both have options to manually set the import units.

Here's Fusion and ZW3d.
