Assignments

[AuRules]

Trying to get a angle from 2 cylinders measured, which that part is easy, but the angle I keep getting no matter how I call it out or measure it, is the largest angle which I need the reverse the small angle. When I was working in MM4 you could take that angle-add a little math functions to it and get the angle you need.

Ex. 2 lines give me the 150 degree angle I need the 30 degree angle so I would create cone1 = cone1.d-180 which would give me -30.00

So that's what I,m needing. I heard some one mention assignments will do that and I have no clue on how to use them.

Will someone for CHRISTMAS (since I'm not getting a bonus)give me a good in
detail answer on how to use assignment and how to use them for a callout. I just need help. Examples help........

I think you might need to reverse the angles of your cylinder vectors. It is a pain in the but thing. I wish PCDMIS would report any angle you want instead of it depending on the measured or constructed feature vector.

I always get the angle I want - not the complimentary angle - by putting the nominal in the field as I create the dimension.

That doesn't answer your question about assignments but it should give you the angle you are looking for.

Sent you back a reply in the private messages post, hope it is correct.

Still need help........Please............

Could you create a generic feature that reverses your vector(s)? The best solution would be to measure them in a manner that gives you the vector you need. I am assuming that is what is causing it. You are right it is a pain in the *** thing to have to do, it would be a nice feature to be able to select what angle you want. Best bet is to post some code. I think your problem should have an easy solution so if you throw some code up folks might jump on it.

Here is what I do. Merry Christmas!
I put the variable in red.

This is for a cone, it is dimensioned only on one side in the print.

F1 =FEAT/CONE,RECT,OUT,LENG
THEO/0,0,-0.1002,0,0,1,0.0277,3.2246,3.365
ACTL/-0.0017,-0.0018,-0.097,0.0004667,0.0004347,0.9999998,0.0278,3.2154, 3.3668
CONSTR/CONE,BF,PNT10,PNT11,PNT12,PNT13,PNT14,PNT15,PNT16, PNT17,PNT18,PNT19,PNT20,PNT21,PNT22,PNT23,,
ASSIGN/V2 = ABS(180-F1.A.MEAS)/2
F2 =GENERIC/NONE,DEPENDENT,RECT,OUT,$
NOM/XYZ,0,0,0,$
MEAS/XYZ,0,0,0,$
NOM/IJK,0,0,1,$
MEAS/IJK,0,0,1,$
RADIUS/0,0,$
ANGLE/20,V2,$
DISTANCE/0,0
DIM D26= LOCATION OF PLANE F2 UNITS=IN ,$
GRAPH=OFF TEXT=OFF MULT=1.00 OUTPUT=BOTH
AX NOMINAL +TOL -TOL MEAS OUTTOL
A 20.0000 0.5000 0.5000 20.1365 0.0000 #
END OF DIMENSION D26

[#2#]

So did inputting the nominal before you create the dimension not work?

Thanks for the help JOHN KINGSTON and all.... Will try it sometimes today and let ya'll know.
