How to add shared parameter to imported dwg in generic model famliy

[Anonymous]

Hi,

We are looking for a solution to import Inventor assemblies to Revit.

We want to annotate and schedule the parts in Revit from Inventor assemblies. 

Now we're importing iam-file (Inventor) in Autocad, via the import command, and save it as a dwg-file.

And then we import this dwg-file to Revit in a generic model family. This generic model family used in a project.

Is there a way to add shared parameters to the imported instances/symbols in the Revit family?

Maybe via macros/add-in?

Thanks in advance!

You can't add parameters to a DWG instance in a family but you can add parameters to a family within a family containing the DWG instance i.e. a nested family that is shared.

You add the parameters to the family document using Document.FamilyManager.AddParameter

To add a Parameter to a family via the API you first need to make a family type and set it current:

(FamilyManager.MakeType then FamilyManager.CurrentType =...)

Thanks for your reply!

So, there is no other way to do this besides rebuilding the assembly in Revit?

Is there code available concerning this topic?

I'm not familiar with Inventor so I can't comment on your workflow. There might be something on the exchange app site allowing a more direct path.

There will not be specific examples for this. I can only note below where to look in the RevitAPI.chm and certain aspects where a greater understanding is required (such as obtaining the built in parameter FAMILY_SHARED).

In addition to the FamilyManager methods for dealing with parameters and types you'll have to become familiar with:

Document.Import & DWGImportOptions

Document.LoadFamily

Document.Create.NewFamilyInstance (overloads)

The parameter named 'Shared' (FAMILY_SHARED) is attached to an object type of Family in the Family document. This Family is distinguished from the others by it's property value  IsOwnerFamily = True
