Issue:

Some users encounter the error message "The CAD interoperability libraries were unable to be located" when attempting to import CAD data. 

Applies to:

• SolidWorks
• CATIA
• CATPart
• STEP
• CAD
• Parasolid

Cause:

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

Solution:

We are still addressing this issue.

• Download the latest Windows update: Users have reported updating their Windows to have solved the problem of importing their parts.
• As a workaround, try exporting a Parasolid (.x_t) from your CAD tool. Parasolid will always yield more reliable results than STEP or native CAD files.
• If this error is occurring with a Parasolid file, try changing the extension from .x_t to .x_b. 
• Try saving your file as a different support file type
• Make sure you only have one version of nTop installed.
