Set Parameters of Multiple Family Documents and Types

Split from original topic:


How can I do it in multiple familys / types with different values?

The problem is your lists don’t match and not everything can be handled by list levels. Your best bet is to duplicate values so you have one-to-one inputs on everything.

Ah good tip! Will try tomorrow

@Nick_Boyts do you mean like this?

It still doesn’t work

I think you just need to flatten the document list. If the inputs have the same dimensions they’ll be treated evenly. Right now that would mean one document per input. A flattened list would put you at one document per sublist of inputs.

@Nick_Boyts Thanks for the reply.

Unfortunately, I doesn’t work:

So this means it’s not possible with multiple familys/?

What does your output look like? Have you messed around with list levels? They may not even be necessary now.

@Nick_Boyts All values in the types are the same.

I noticed you also have lacing set on the node. I’d change this back to auto if you haven’t tried that already. Worst case scenario you should be able to duplicate the document list as well. It’ll probably be a lot slower but it should force everything to align correctly.

With auto the same result. So the document and the types the same, and the parameters/values?

Orcon.xlsx (10.1 KB)
Test.dyn (69.2 KB)

Over here some files if someone want to test.

Can you share families as well? Or setup an example set that can be shared?

Sure, in the appendix 3 rfa files.
In this case I use the excel file for the rfa files and the parameter, not for the values yet.
57_ME_UN_HRC-300-500 rechts_Orcon.rfa (1.7 MB)
57_ME_UN_HRC-300-500 links_Orcon.rfa (1.8 MB)
57_ME_UN_HRC-425-570 links_Orcon.rfa (2.6 MB)

My endgoal is set all the parameters in all the types with all the values from my excel.

I had no luck either. Might be time to get @erfajo involved.

i tried it with python yesterday. there I had retrieved the types from the familys and if the parameter matched the input, then take the parameter per type. but the point is that they are family parameters and not familytype parameters.

What do you mean by this? A Family Parameter refers to where the parameter is being applied from (family vs project or family vs shared). A Type parameter refers to how the parameter is applied to the element (family type vs family instance). I don’t think any of this should matter when you’re interacting with the family in the family environment. The family document will have both the type and the instance parameters so you should just need to find the match.

@Nick_Boyts This is what I have, but somehow it doesnt work:

I retrieved the parameters for each type but somehow it doesn’t do the trick.

After that I used the Set method and save the doc but revit crashed after that and the family is saved 3 times.

I don’t know if this will fix everything but your lists don’t match in structure which I think is still going to be a problem. We can’t actually see all the inputs as you’ve supplied them so I’m only guessing based on your code structure.

You don’t show where values comes from but I’m assuming it’s a list of values that you supply as an input. I would have assumed the same for params since you first went through each type and identified them but you then define params as all parameters in the family manager again. This also makes it seem like params and values no longer match. Similarly, you haven’t shown where fam_types comes from but assuming it’s the type list you also had created the structure doesn’t match and you’re now trying to assign parameters to every type within each document, not just the family the types came from.

In my mind, it would be easier to set the parameter in the first python block instead of redoing some of the work a second time. It may also help with maintaining the proper list structures.

Side note: I just now realized this wasn’t originally your thread and we’ve pretty well hijacked it. I’m going to see about getting it split into a new thread.

It doesn’t work, so I had everthing in structure.
So as I understand you well, I need to create list for each doc with his own parameters?

Hehe, yes good choice :slight_smile:

I still haven’t seen the inputs for the two python blocks so I can’t say for sure, but the looping structure doesn’t seem to match your intent. So yes, a list of docs, a list of parameters by doc, and a list of values matching their parameters.
