run a rule when a parameter change

[Torben.pedersen]

hallo there

I what to make a rule, that updates / run automaticaly when the diameter change here is an exeampel:

if Dia1 change then

run rule BT

end if

I know I´m not using the right terms, thats why I need some help 🙂

hope this makes sense to you, or else feel free to ask questions 🙂

Hello,

Could you attach your file so i could have a look?

You could create a rule so when DIA1 is a certain size, or more, less than a certain size, it will run a rule.

If you attach your file i will show you what i mean.

I'm afraid I can´t attach the file or I'm not allowed. ( furthermore the parameter name´s are in german )

I know I can set i up like you explained, but that´s not what I need.
I need the rule to do as previously explained, is that not possible or  is the only way to do as you described? 🙂

[Thomas_Savage]

Hello,

Yes you could do it. 

But without looking at your part it is harder to create a rule.

What i was saying in my previous post is. You need to specify what size the the dia changes to, to run rule.

So you could do something like this:

If Dia1  = 20 Then

iLogicVb.RunRule("RuleName")

End if

If you don't specify a size of diameter, how will it know when to run the rule.

And place the rule you want to run in ("RuleName")

You could put any size you want, i just put 20 for an example.

you could also do < > before the = so it is more or less the size.

Hope this is what you mean?

Thomas.

so could I do somthing like this:

If Dia1  < (less then) 9999999999999999999 Then

iLogicVb.RunRule("RuleName")

End if

and then every time I change Dia1 and it´s less then 9999999999999999999 mm the rule runs?

[salariua]

is this what you are after:

Check my attached part made in 2017.

I have created a "Check" parameter and when diameter is different than check value it will run the second rule and update the check.

First rule

If Parameter("Check") <> Parameter("Dia") Then
	iLogicVb.RunRule("DiaChanged")
End If

Second Rule

Check = Dia
InventorVb.DocumentUpdate()

MessageBox.Show("dia changed to: " & Dia , "i")

[Thomas_Savage]

Hello,

Like this:

If Dia1  <  = 9999999999999999999 Then

iLogicVb.RunRule("RuleName")

End if

Try it and let me know how it goes.

Thomas.

Hello,

I forgot to put the update as well.

If Dia1  <  = 9999999999999999999 Then

iLogicVb.RunRule("RuleName")

End if

InventorVb.DocumentUpdate()

Try it and let me know how it goes.

Wouldn't this be TRUE all the time not just on diameter change?? so the rule will run every single time rather than just when diameter changes?

[Thomas_Savage]

Hello,

You're welcome.

Glad it worked.

Thomas

Hello,

I am sure it would only run the rule when the diameter is changed?

So if you don't change the diameter, it will not run the rule.

I usually use the more, and less than and it only runs the rule when i change the size.

I am not on a computer with Inventor at the moment. So cant test it.

But i am sure it will not update until the diameter is changed.

Thomas

[Torben.pedersen]

the rule will only look at the Dia1 when it change I guess, and that is what I need

[salariua]

well... if you are happy... so are we.

you need to limit the number of digits on 999999 check or you will get an error

keep in mind there is a limitation with this and that second rule will run sometimes run even if diameter has not changed...

[Torben.pedersen]

yeah I found out with the digits, I set it to 20 because it will never be more than around 10 and not under 1,5
so I could also change the rule to only be active between those numbers

[Torben.pedersen]

the rule looks like this now: 

SyntaxEditor Code Snippet

If BB <= 20 Or BB >= 1 Then
iLogicVb.RunRule("BT")
End If

InventorVb.DocumentUpdate()

[Thomas_Savage]

Yes i usually use less then a size, and more than a size.

Your rule looks good.

Thomas.

[Torben.pedersen]

cool thanks for the help, I really only need a push in the right direction, and the it comes to me 🙂

[Thomas_Savage]

You're welcome.
