From version 3.6 has been implemented non standard profile tolerance for GSURF, CURVE and POINT features. 
 
The difference from the ANSI is that, using the 3D profile, the deviation is calculate along the 3D vector that joint the measure point and the nominal, while, in the standard , the deviation is along the normal direction of the nominal point. 
Although not in the ANSI standard this tolerance is quite common in the automotive industry. 
The different methods can be called from the '''PROFILE''' of '''POINT/SURFACE/CURVE''' tolerance panel. 
The [[DMIS]] code created in the two cases is as follow:
 

<CODE>
F(POINT_PROFILE_ANSI)=FEAT/POINT,CART,0.0000,0.0000,0.0000,0.00000000,0.00000000,1.00000000 
F(POINT_PROFILE_3D)=FEAT/POINT,CART,0.0000,0.0000,0.0000,0.00000000,0.00000000,1.00000000 
FA(POINT_PROFILE_ANSI)=FEAT/POINT,CART,0.10000,0.20000,0.30000,0.00000000,0.00000000,1.00000000 
FA(POINT_PROFILE_3D)=FEAT/POINT,CART,0.10000,0.20000,0.3000,0.00000000,0.00000000,1.00000000 
 
V(TEXT)=VFORM/ALL 
DISPLY/TERM,V(TEXT) 
TEXT/OUTFIL,'This is the Standard ANSI profile Tolerance' 
T(ANSI_PROFILE)=TOL/PROFS,-0.1000,0.1000 
OUTPUT/FA(POINT_PROFILE_ANSI),TA(ANSI_PROFILE) 
 
TEXT/OUTFIL,'This is the NON Standard 3D Profile Tolerance' 
T(3D_PROFILE)=TOL/USETOL,'PROFS_3D',-0.1000,0.1000 
OUTPUT/FA(POINT_PROFILE_ANSI),TA(3D_PROFILE) 
DISPLY/OFF 
</CODE>
