If the problem occurs in specific drawings:
Please try to call the BATCHPROCESS command and use this utility to correct errors in the drawing. You can also find this utility in the main menu of the program -> Utilities - Batch file processing:

If the program freezes in the process, or error correction does not help, please send a request to our technical support - https://support.nanocad.com/, attaching the problematic file if possible.

If the program is slow with any drawing (even on empty):

Please try to select a different Vectorizer Type in the Options window: 

There are three ways to find the Options window:
  • Right-click in the program's operating window -> Options
  • Press Ctrl + 9
  • Call the Options command

If nothing helps, also submit a request to our technical support - https://support.nanocad.com/, specifying your version of nanoCAD, and, if possible, attaching a file of information about the system:
  • Click the Windows Start logo.
  • Type "MSINFO32" or navigate to and click %windir%\system32\msinfo32.exe. This opens the "System Information" Window.
  • To save the file in the native NFO format, from the File down menu, click Save.
