When importing SOLIDWORKS or STEP files the error message "Unable to translate any data from selected part" appears


  • On CAD import the user encounters the error message "Unable to translate any data from the selected part."

Applies to:

  • nTop 2.19, nTop 2.20
  • SolidWorks, STEP


This error message occurs when there is a conflict or missing file relating to nTop's translators.


No known solution at this time. As a workaround, try exporting a Parasolid (.x_t) from your CAD tool. Parasolid will always yield more reliable results than a STEP or native CAD files.

  • Hello Matt,
    Just add this problem with the new version . I'm not able to load any of my IPT file within Ntopology software.
    It has previously worked already with these files but now it is not possible to load them. Same issue when I import a STEP file.
