Hello GUICAD

The error in the log file simply says the file failed to import and it shows the file path. Have you tried moving the file to a local directory?  It appears from the log file that the STEP file is located on a network drive (W:).  While importing, SpaceClaim often creates a temporary file.  It's possible that the temporary file is being blocked and therefore the import is failing. 

Regards.
