Issue:

• nTop supports importing part files but not CAD assembly structures. 
• SolidWorks assembly files (SLDASM) are unsupported by nTop.

Applies to:

• nTop 2.23
• SolidWorks
• SLDASM

Solution:

The ability to import CAD assembly files is a popular feature request that we are exploring. A workaround is to save the file as a Parasolid (X_T), but be sure to check the SolidWorks system setting for Flatten assembly hierarchy.

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