Display parameter from nested family

[adcdao]

Hello everyone,

I developped a small arrow family with dimensions validation. I also added a text parameter to show message if dimensions are invalid. It's working well.

Now I nested this family into another one and I'm able to drive the dimensions of my nested family using host parameter as usual. But, If the dimensions from the host family are not valid I'm not able to retrieve the parameter displaying the error message from my nested family.

I hope you understand my request. Is it possible to do that?

Thanks,

André

Have you created a parameter in the host family and then mapped the nested parameter to it? Does the Associate Parameter button appear for the nested family's parameter?

Hi,

Yes I created a parameter in my host family but the associate parameter button is not available. Maybe because it's a read-only parameter because I have some paremeters use only for calculation and they are also not available.

How about if you do the validation in the host family?

It's a possibility but if I use this family in multiple hosts, it's annoying to repeat the same validation on each host.

If a formula greys out a parameter in the nested family it will make it so it cannot be linked in a host family.

Formulas that have 2 or more references to other parameters or if statements will  grey out a parameter.

As @Alfredo_Medina said you should have the formula in the host family.

Here is an example of what of formulas that grey out parameters.

With the "1 Reference" formula if I change the parameter value it will update the "Input 1" parameter as the formula is saying "Input 1" is the same as "1 Reference" - 500

Thank you for your explanations,

Use instance, not type parameter, in the nested family.
