Creating family from a project document

Anonymous — Tue, 29 Sep 2015 16:46:27 GMT

Hello,

I am trying to create a family from a project document. In other words, I want to open a common project document and programmatically (there is a button) create an extrusion. Until now I saw that to create an extrusion I can use the FamilyCreate command. However it seems like FamilyCreate can only be used from a family document.

Is there any way to open the FamilyEditor or something like this from a project document?

Thank you,

Carolina.

Hi Carolina,

What I know is that from the Revit Project you could edit the Family previusly created. To edit an existing family while working in a Project document, use the EditFamily() functions available from the Document class, and then use LoadFamily() to reload the family back into the owner document after editing is complete.

To create a new family document use Application.NewFamilyDocument().

Also keep in mind that API access to system family editing is not available.

The ability to modify Revit Family documents and access family types and parameters is available from the Document class if the Document is a Family document, as determined by the IsFamilyDocument property.

You can read about this in the Revit Help file.

I don't know a way to create a family within a Revit Project. Maybe the workflow you are planning could get a different route to achieve what you are trying to do.

Also when in doubt I always re-visit Jeremy's explanation about Revit Families, an old post but very very informative.

Hi Carolina,

you may have a look at the DirectShape classes.

Using these, you can create Elements from any input geometry, both in project and family context.

It seems like it can solve my problem. However I am not getting to access the DirectShape classes. What namespace I need to use? Are DirectShape classes available in Revit 2014?

Hi Carolina,

I'm afraid DirectShape class got first introduced for Revit API 2015.

It's sad... I think I will have to change the way that I was pretending to do this.

Thank you Jaime Rosales and Revitalizer.

Dear Jaime,

wouldn't it be useful to let the thread poster choose a Revit version for his (or her) problem ?

Just provide a combobox containing all versions up to 2016, with multiple selection enabled.

A compulsory input field, to be filled in before the new posting is published.

I wouldn't have suggested DirectShape if I would have read "2014" in the initial posting.
