    STEP export with user coordinate system

    Jeff Blasius

      We are just beginning to use CircuitWorks to import board designs from Altium Designer and having some growing pains.


      The EE on the project wanted a set of STEP files for performing a visual verification in Altium Designer. However every file I created was not oriented properly. When exporting the STEP files I choose to use the CWX coordinate system in the Export-Option dialog. When the files were imported into Altium Designer, the data was referenced back to the default coordinate system. I found a work around, but am wondering if maybe something else is wrong. The work around is to:


      1. Export to STEP choosing the CWX coordinate system.
      2. Close the part file.
      3. Import the STEP file into SW.
      4. Heal any faces.
      5. Export to STEP again.


      We are running SolidWorks 2012 SP03. Any insight is appreciated.


      Thank you,

          I don't know why Altium isn't seeing the parts with the assigned coordinate system, but I can tell you that it is very important for the EE and the ME to agree on the origin and orientation of the parts. We normally let the EE choose how he wants the parts to be set up. Altium changed their orientation a year or two ago, so the PCB face was no longer Top but Front. We had to reorient all of our parts. (One of the guys wrote a macro to do it.) What a pain!
