The ACMPROFILE system variable indicates if the current profile is an AutoCAD Mechanical (ACM) profile or not.
ACMPROFILE = 1, indicates that the current profile is an ACM profile
ACMPRIFOLE = 0, indicates that the current profile is not an ACM profile
This is only an indication and does not enact a switch from an ACM profile to a non ACM profile.
