for some reason i cannot insert the attached object to revit link (but can insert to a wall created locally)
This Family is built to specifically host to a Wall Element within a Revit Project. When used in a Linked Model is involved - these Families CANNOT host to an Element within a Link Model. Therefore, Families that are hosted to a Face are necessary. Any element-specific Families (i.e. Wall, Ceiling, Floor) can be converted to Face-Based with the following procedure:
1. Create a new Project and draw a Wall.
2. Load in the desired Family and place one instance of each Type on the host Element. Exclude Types you do not wish to retain.
3. Save this Project somewhere temporarily and close it. Start another new Project.
4. Link the previous Project file into this one. The placement of the Linked Model is irrelevant.
5. Go to Collaborate tab » Copy/Monitor ▼ Select Link. Select the Linked Project and use Copy to create a copy of each of the placed Elements.
6. The Family is now converted to Face-Based and may be saved/exported from this Project to a separate file for later use.
Note: Only certain Categories are available for Copy/Monitor. If the desired Family is not of one of these, you can edit the Family prior to this process and temporarily change it to an applicable Category and then change it back when completed.
