Autocad returns “Unknown command”
Hi there,
According to AutoCad Knowledge base:
Causes:
This problem occurs because the AutoCAD software is unable to load the function definitions in the acad.mnl file. Commands such as Make Object’s Layer Current and Deselect from the Right-click ShortCut Menu (among others) are defined in the acad.mnl file and do not function unless this MNL file is loaded in memory. Several AutoCAD core functions are defined in acad.mnl; if you modify menus or load menus other than the default without regard to this fact, the acad.mnl file may not load. In this case, the functionality is never defined.
Solution:
Alternatively, make a copy of the acad.mnl file with the same file name as the MNU file:
- Make a copy of the acad.mnl file.
- Rename the copy of the acad.mnl to the same file name as the main MNU file you are loading. For example, if you are loadingmymenu.mnu, rename the copy of acad.mnl to mymenu.mnl.
- Restart AutoCAD so it loads the MNL file you created
Hope this helps 🙂
