command syntax in GRIP

command syntax in GRIP

command syntax in GRIP

(OP)
Hi to all ,

1.
I have created a simple GRIP prodram, to create pins.
I have used SOLCYL for the two solid cylinder, but i couldn't find a way to unite them into a solid in the GRIP program.
Can anyone please enlighten me on how to unite them using GRIP.

2.
I have create in the prt file some expression, eg :p0=100,p2=35, etc.
Can GRIP change this expression?

Your help will be greatly appreciated.

Thank you.

GRIP has not been enhanced for the parametric modeling paradigm that was introduced at V10.

The SOLxxx commands are left over from V7, when UG/Solids was introduced. There are no boolean functions in GRIP.

The only expressions taht GRIP can modify are the old calculator registers A-L. You can get GRIP to modify expressions, but the MUST be named A-L and you are limited to the 12.

We use a program to create hardware items using the ability of GRIP to modify the 12 A-L expressions. I think the most we actually use are 9 for shoulder bolts.

There are no boolean operations in grip. It does, however, have commands to edit expressions. In the grip help file look under "System control - Expressions". The help files don't list the A-L limitation, but Ben is usually right (I'd at least give it a shot though).

It sounds like what you really want is a user defined feature. At this point I would usually point you to the help files, but I've been playing around with them for a while and still have not been able to get it to do what I want. Maybe another member can enlighten us.

Yankw,
   Maybe you should look into Knowledge Fusion instead. It can do those tasks that you are refering to.

RE: command syntax in GRIP

I remember using a unite in a GRIP function for a program I wrote back about nine versions ago and it worked fine. It model a bent bar using cylinders and spheres. Now, I'd use the Tube
function but that was not around at time. Anyway, a quick look at GRIP Manual shows the Command UNITE/obj,WITH,objlist1 :Where obj is target object and objlist1 is a list of the tool objects.

I've not tried to access the expressions from a GRIP program but the manual shows a set of commands. It says the command to edit an expression is:
EXPEDT/exp_string_list[,IFERR,label:]

Best of luck with the program
Have Fun
