View Full Version : Unique parameter values from hosted family

September 19th, 2014, 08:41 AM
I have a problem with getting unique parameter values from the host family.
I have created a pile(as a stick) family and added an shared parameter into it. Then i put this pile family into pile cap family.
The problem is when i use it in the project and my pile cap has more than 1 piles in it, they will inherit the same value.

How could i give the piles different parameter values. I can only give the parameter a value by giving it to the whole family, i need to give it to the piles itself.

Thank you

There are, at least, 2 options:

Option 1) In the host family, create several copies of the nested pile. Also, create one parameter for each property of the nested pile. (e.g. "size of pile_1", size of pile_2", ...). Then link the parameters of each instance to its correspondent unique parameter in the host. (e. g. first pile to "size of pile_1", second pile to "size of pile_2", ...). Even if you have several instances of the same nested family, its parameters can be linked to different parameters in the host file.

Option 2) Set the nested family as shared. Load this shared family into the host, and create multiple instances of it in the host family. Then, in the project, use the Tab key to select each pile, and then enter values to modify its instance properties.

(EDIT: See my next post for correction/additional instructions).

Thank you for the answer but it does not work.

May I describe the problem with my example.

I have a small family which is used to gather coordinates for my piles. A small family called Einfügepunkt. i have added it a description which is made into shared parameter.
Einfügepunkt is added on the top of every pile. And 4 of the piles which include the coordinate thingy are added inside the Pile cap family. And when i go in the project then I can only change the Pile Caps description (shared parameter) and when I use tab to select individual piles, then the Description is GREY and cannot be changed.

Someone please give some hints or when it is not possible, SAY so : )
Thank you

In the host family, link the shared parameter of each nested shared pile to a unique instance parameter (if you need to schedule this parameter, make it instance, too). In the project, select the main host family, and enter a value for each parameter, such as "Id_1", "Id_2", ... etc.
