iLogic Form - Read Only

[matt_jlt]

Hi everyone, I was wondering if there is a way to modify a user form parameter's read only status using a rule?

I have a parameter that I want people to be able to edit when another parameter is set to true and to be locked if it's set to false. The only thing that comes to mind is have a rule that will just switch the value back automatically if the user changes it but it would be good if i could control the read only status.

Thanks, Matt.

Hi Matt,

If you want to make a parameter in a form Read-Only based on a parameter's True/False value then you can just set that parameter for the "Enabling Parameter Name" in the form.

If the problem is that instead of making the value Read-Only when the parameter is False, you'd like to make it Read-Only when the parameter is True, then you could create an additional parameter and a associated rule for the locking parameter that would keep these two parameters' values opposite, and then use this extra parameter for the "Enabling Parameter Name"

Here are some pictures that should make it clearer what I mean:

Hi Adam, is this functionality only available in 2013? I'm stuck on 2012 as where I work only swaps over versions every two years.

I guess I'll have to use my workaround until 2014 comes out.

Thanks for your help.

Matthew.

Hi,

I could achieve the exact same thing in Inventor 2012 as well - attached is the part I created.

When you modify the LockMyParam parameter to false then the MyParam edit box becomes read-only.

Question?

You may do the same exercise but with a numeric parameter?

Apologize for my bad English.

The help text for the "Enabling Parameter Name" actually answers it (see the picture of the Form Editor dialog above): "The name of an Inventor True/False parameter. ..."

So you would need to create such a parameter, which could then be driven by a numeric parameter.

E.g. create the True/False paremeter named DontLockMyParam and then create a rule that drives it. Something like:

DontLockMyParam = (MyNumericParam < 10) ' If the numeric param is less than 10 then the parameter will be enabled
