Hi,
Can some body help me in writing if or else statement to the parameter when iam adding formula to it.
I have to write something like this, ID=if(OD-(H-E-F)*2<Thread_major_dia)(Thread_major_dia)else(OD-(H-E-F)*2)

I have the parameters created for OD, H, E, F, Thread_major_dia,Thread_major_dia

But after i say ok, iam getting error like this" invalid structure: Syntax error"

I think you can't use if statement directly on formulas. You have to create a rule.

Rule syntax is
Statement
Parameters behaviour

Like this

IF A==5mm
{
B=A+2mm
C=A/2
}
ELSE
{
B=A+4mm
C=A/B
}

Check the statement operands from Online Documentation.

Hi,

This is a pretty old mail i suppose, do we need KWE module for giving these types if rules?

Is this not possible for us to give these rules in Part design workbench?

Cheers,
Mah.

maha,
yes, you need a KWE license to create rules and checks. You can creatre simple parameters and such in part design, but no Rules....

You need a KWA license (Knowledge Advisor) not a KWE license (Knowledge Expert).

Thanks Mark & Cliff,

That was really informative, and cliff thanks that you are so precise in what you said, because some people say it as KWA and some KWE, so got confused with it already.

I tried out knowledge advisor, but there too i didnt know how it works. I entered the code in VB script dialog box that was opened, and there was an option called run in that, there were no errors, but nothing happened after that, i have to learn online help to find out what the problem was.

I also tried to create parameters in KWA, but i was not able to create as i do it in part design.

anyway if you have any basic material on KWA, do let me know.

Cheers,
Mah.

That code is for a KWA Rule, not a vbscript.
I'm a little suprised you didn't get an error, the operator "==" is not valid vbscript.

Hi all,

No need of KWA and some KWE.

You can create "fog law" for this type of simple if and else statements.

Fog law can be created in Part design.



Thanks

Is it possible to do this with a SIMPLE script for those without KWA?

If so, can someone submit such a simple example?
