PELLIPSE Command not working

[Anonymous]

Using AutoCAD Mechanical 16, my coworker's machine no longer allows him to use the PELLIPSE command. Anytime he types in PELLIPSE it just enables the ELLIPSE command. He's trying to change the pellipse value from 0 to 1. The problem is only on his machine. Any ideas if there was a setting he accidentally enabled/disabled that we can change back?

have them try .PELLIPSE (include the period) and see if it behaves as expected

Or try (setvar 'pellipse 1).  PELLIPSE isn't a command, but a System Variable.  Some time ago AutoCAD added the possibility of setting System Variables by entering their names as if  they are "commands," but they're not really.  It would be possible for a custom command to be defined under that name, but if so, the (setvar) approach should still work.

What happens  when they try?  Any error messages?  Any prompts, etc., if there's a custom command defined under that name?

when he types in "pellipse" it just activate the "ellipse" command, as in he can draw an ellipse.

The "setvar" command is a good work around, but we aren't sure what caused the original issue. Thanks though!

And when he does then go ahead and draw one, is the result always  a Polyline approximation of an ellipse [not a true Ellipse entity], regardless of the PELLIPSE setting beforehand?  If so, I can imagine that there's a custom definition of a command named PELLIPSE that changes the System Variable setting and then calls up the Ellipse command.  Someone might define it that way on the assumption that they would set the System Variable to draw ellipses as Polylines only when they then wanted to proceed to draw  such an ellipse.

Check the "usual suspects" such as the ACADDOC.lsp or ACAD.lsp or .mnl file, files loaded by them, or the APPLOAD Startup Suite for something that includes:

(defun C:PELLIPSE

in it.
