nanoCAD Free (nanoCAD v.5) can't open a DWG-2018 file

nanoCAD Free supports DWG file versions up to 2013 only. Please verify the version of your DWG file by following these steps:

  1. Open the DWG file with any text editor (such as Notepad).

  2. At the beginning of the file, you will find a code in the format: AC10XX, where "XX" varies and could be 32, 27, 24, 21, etc.

  3. The code "AC1032" indicates that the file is in the DWG 2018 format.Ā To work with DWG files of this format, upgrade to the nanoCAD Platform.


If your file is version 2013 or earlier and you still encounter issues, attempt to recover the file by using nanoCAD Platform:

  1. Run nanoCAD 24, then call theĀ RECOVER command to open the file.

  2. Unfreeze, unlock and turn on all layers.

  3. Call the RMPROXY commandĀ - Nongraphicalproxies to remove proxy objects which do not have a graphic. You can also use theĀ XPROXY command to explode visible proxy-entities.

  4. Use theĀ Purge command to clear waste objects. We also advice to use theĀ PURGE command (works in the command line, without dialog) and use its different options, especially ANnotscales and sorTTable

  5. Select all, then call theĀ Flatten command. You can do it twice, because some objects can be flattened only the second time.

  6. Use theĀ Audit command.

  7. Use the Audit Geometry command twice: first audit z-coordinates, then hatches.

  8. Sometimes it is necessary to repeat steps 3-6 several times to fix the file.
