problem command estrudi his autocad 2015 for mac

[Marco_C]

Good morning, everyone!
no one has encountered problems with the command "extruded" on the 2015 autocad for mac?
It seems that the command does not respond... I'll explain. .

I have to do a very simple extrusion of a closed polylinea.
If I try to use the preset command in the toolbars I have this result:" _extrude unknown command "extrude". press f1 for help."
I think... will there be a mistake in the macro?
I open the command customization window and find two commands with the name "extrude":

• he first

name: extrudeDescription: creates a 3d solid or surface by extruding a 2d objectmacro: _

• the second

name: extrudeDescription: creates a 3d surface by extruding a 2d or 3d curvemacro: ^c^r_extrude _mo _su;

what I was using was the first... The right one in theory... But why doesn't it work?
Is the macro wrong?
