How a Generic Model elements to host reinforcement by revit api ?

[Anonymous]

I tried to change a family file,which set the 'can host rebar' to true.

I get the information from this page:

http://help.autodesk.com/view/RVT/2014/ENU/?guid=GUID-482810DC-1C37-41CD-85B2-3EB89C33D5BC

the note:

"

Note: You can enable Generic Model elements to host reinforcement. Open the element in the Family Editor. On the Properties palette select Can Host Rebar in the Structural section. Reload the family into your project.

"

But I do not know how to make it by revit api.

Could anyone tell me anything about it?

Thanks very much!

In the API, open the the family document, set the property, save, close and reload the family document into the project document.

The Building Coder shares code showing how to achieve some of those steps:

Probably it includes code for the other steps also.

You just need to search a bit.

Sorry distrub you again.

I tried search the key word "set property" in your blog.Get some programme，but it shows useless.

 I may understand  by a wrong way.

In my understand, I  think the parameter or property can change by setting  a value ,like false or true or something else.

Firstly, I try to get it by the way get_Parameter(),or Parameters and out put all the parameter's name.But I did not get the "can host rebar".

Also I tried the get_Parameter(BuiltInParameter.FAMILY_CAN_HOST_REBAR),(ps: the BuiltInParameter.FAMILY_CAN_HOST_REBAR , I think it may about what I want), return null.

So,I think the word "property" you mean ,I understand the wrong way, it is not a parameter.

And then, I think it may be a global setting of the document?

I tried to search the Setting class, tried to out put the Categories and TilePatternBuiltIn,it may not the way to set property.

Could any more tips?

No problem. Thank you for sharing your research so far.

I do not know where the property you are looking for might be stored. I would have to search for it too.

You can do so using the Revit database exploration tool RevitLookup:

https://github.com/jeremytammik/RevitLookup

I very much hope you are aware of and using it it already.

You should first determine exactly where the property you are looking for appears in the user interface.

What element or document is hosting it, is it a built-in parameter, which built-in parameter, etc.

Then you can use RevitLookup to search for the exact path to retrieve and set its value via the API.

I hope this helps.

Cheers,

Jeremy

Sorry distrub you again.

But this time is the good news(May the word news is not suitable).

Finaly,I get the "Can host rebar" Parameter by the tools you  provide.

From the DB data, I easy find it :

document(which is familydocument) -> OwnerFamily -> parameters -> can host rebar

the wrong thinkings about before:

document - > familymanager -> parameters -> wrong

And now,I want to change the value: I think I can complete it.

Thank you very much.

Thank you teach me how to catch fish by finshing net,which I was by hand before.

according to your last reply,I set the "family_can_host_rebar" whether in familyInstance or in family document ,for example :

Parameter parameter = box.get_Parameter(BuiltInParameter.FAMILY_CAN_HOST_REBAR);
parameter.Set(1);

or:Parameter parameter = familyDocument.OwnerFamily.get_Parameter(BuiltInParameter.FAMILY_CAN_HOST_REBAR);

parameter.Set(1);

but none of the settings work,still  "not a valid host" ( rebarhostdata.isvalidhost),do you have any advice to help me solve the problem ?
