Notes:

  • ^ is equivalent to pressing Ctrl key. Therefore ^G means press Ctrl+G and ^E is equivalent to pressing Ctrl+E.
  • AutoCAD will not add Enter to those lines that end to control characters.

5. Save the file and load it as a partial menu.

Note: To learn more about partial menus read the following tutorial:

Notes:

  • !. puts a tick mark beside the menu option.
  • ~ disables the menu option.
  • $(getvar,isolines) will return the current value assigned to the ISOLINES system variable.
