Creating a Unique Wall Type:
It was necessary to create a specialized wall type that specifically suited our needs for our modular housing design type. We were able to do this in RevitArchitecture2009 by drawing an exterior wall and editing its properties and renaming the wall type. We renamed it ProtoType01 (PT01). The following are the steps we used to create our custom wall:

1.Draw a "Wall" in Revit:

2. With "Modify" selected, right click on the wall and select "Element Properties":
3. In the "Element Properties" dialog box, select "Edit/New..." next to the "Type" drop-down menu :
4. In the "Type Properties" dialog box, select "Duplicate..." next to the "Type" drop-down menu:
5. In the "Name" dialog box, appropriately rename your wall type and click "OK":
6. In the "Type Properties" dialog box, select the "Edit..." tab next to the box labeled "Structure":7. In the "Edit Assembly" dialog box, modify, edit, and rearrange your wall section to suit your specific needs.

8. When finished, click "OK" to everything and your new wall type will appear in the "Wall" drop down menu:
