Conditional Statements controlling expressions

Conditional Statements controlling expressions

Conditional Statements controlling expressions

(OP)
Hi,
Can anyone give me some advice regarding controlling an expression with a conditional statement ?

I'm using NX 7.5.5.4 MP2

I have two linked bodies in a part. There is an angular expression controlling the position of these bodies.
There is a plane constructed between the bodies and a far measurement feature so I have the area of the plane as an expression.

When the angular constraint changes, this alters the plane and therefore the area.

I want to control the angle by entering the area.

I have the following expressions:
-Angle
-P200 (face measurement area)
-Targetarea

So far I've been trying to alter the angle expression by relating it to the areas, using :

IF (P200==Targetarea) THEN () ELSE IF (P200!=Targetarea) THEN (Angle=Angle+1)

My questions are:

- Am I attempting this in the right way ?
- Is this the easiest way ?
- Can I make a value 'step' like this ?
- Once P200==Targetarea, how do I stop the loop?
"IF (P200==Targetarea) THEN (??)


Any help would be greatly appreciated.

Cheers

Gavin
