Hi Guys!
I'm hoping someone can give me an advice on how to correctly input formulas in my bracket family. This is the case:
1. I have a bracket with two types of support, Support Type 1 & 2 parameter.
2. What I want to achieve hopefully is when I tick Support Type 1, Height 2 and Height 3 parameter will be greyed out.
3. And, if I select Support Type 2, Height 1 will be greyed out.
The intent is for users to avoid changing unnecessary parameters that is not related to the support type they want to use. Attached is a simplified Revit family. Thanks in advance!
.
No can do. The only way to grey out parameter is to enter a formula.
Now, what you could do is put in some instructions to the user. We do this in some of our families. An Instance Text Parameter Grouped under Constraints could deliver a more serious 1-liner like in this example:
Hi @barthbradley! Thanks for looking. I'm ok to have a formula but not sure what other restrictions I can put to make the goal achievable. Are you able to advice? Thanks.
Well, the formula would force a value for that parameter. Is that really what you want to do?
Can that value be within a range so user has some flexibility to enter any number within that range?
Nest your family into 2 other families and associate only the parameters that you wish to be accessible. See attached file.
