Changing model using length & Drop down parameter

[Anonymous]

I have created more than 50 families in revit with length & drop down parameters. Now my model is changing according to length. But i want to change my model in both ways(Length & drop down tick box). So please give me a solution for this.

Edit the families and add the parameter.

Good luck!

Thanks Rob. I have done all this before but still it's not working

I don´t know how you pretend to change family dimensions with a yes/no parameter. I don´t think it would be an easy task 😕 If you really wanna do this, you could create some kind of if(tick value, true result, false result with all ticked possibilities). You will have a full-page formula, so write-it on notepad and bring it back. 

ex. If (1193, Lenght_M*1193, if (1255, Lenght_M * 1255, if (1318, Lenght_M * 1318, etc.............)))

Why don´t you just create many types with the length dimensions?

Why not just create the types which set the length (doesn't that do anything? You have a shared length parameter?) and the corresponding type parameter, or associating the length to the nested family lenght parameter in type properties... so, not sure if I understand what you're looking to do actually...

Thank you Alan
I have already done these but still i can't find the solution for this.

...still unclear what you are looking to do. Perhaps share the family and elaborate.
