You seem very intent on forcing Revit to model this, contrary to multiple suggestions otherwise.

What is your actual goal with this family?

Are you including the host along with the sweep? If you're using Reference Planes as the host, try selecting the sweep and the Reference Plane (in a plane view) and use Rotate with Copy checked.

I can appreciate that. I'm new at a design company and learning 3D modeling for them. My goal is to prove how close I can get the look, because scaling it back is the easy part. Here's where I'm at now with this, and I'm moderately pleased. It just bugs me that it's so close and I can't figure out the HOW to do the extra little steps. And I still have such trouble with cutting voids most of the time.

I think you nailed, Steve. I'm trying to further wrap my head around "host-talk", and if by "plane view" you meant reference level or elevation, but the Rotate with COPY checked was the kicker.

What I did was rotate the sweeps with COPY checked, then copy/move THOSE so they would release from the plane and move.
Thank yall so much for all the help. There's no one around I can ask about this material.

UPDATE:
Well it worked for the lower half of the sweeps. Now I'm stuck again just sliding along a plane instead of moving .....
2xUpdate: Well hell, now it's working. So yay? Lol, it's sooo finicky. It releases from the plane when after the 2nd copy you immediately try to move it. Don't click elsewhere.

If you are trying to achieve a certain "appearance" in orthogonal (plan, elevation, section) views, you can hide all the geometry and use a Detail Component to display the linework you'd like to see.

You may also want to look at importing geometry. I believe importing geometry into a DirectShape (through the API) is currently the "state of the art" in imported geometry in Revit families.

Is there only one size , style, or type of fixture, or will this need to be made parametric?

Like your desk and everything on it...the desk is a work plane and everything on it is hosted by that plane. Revit is a work plane world, everything relates to one. In a project most elements relate to a Level just like everything in a real building relates in some way to a particular floor in a building.

When you create a Revit family each solid/void form has a relationship to a work plane too. Most of the views are assigned to a particular work plane in each template so it may not be entirely obvious at first. It's up to us to define work planes and create relationships to them for each solid/void...or at least make sure the correct one is assumed based on the view we are working in. We can reassign a view's work plane (see left image).

Each scroll's sweep has to be hosted by a work plane (Reference Plane, Reference Line or solid/void form). When you try to copy a sweep without its work plane it generally fails because it needs to have a host. There are some situations where Revit will copy a form but allow it to lose its associated work plane. If you select a solid or void you'll see what work plane Revit has associated it with in the Properties Palette (right image).

You can reassign an element to a different work plane but it has to be parallel to the original one when you use the Edit Workplane feature.

Oh wow. That's really interesting! I'll definitely dig more into those ideas. No, this one doesn't need to be parametric, so that takes some heat off the table.

This is brilliantly put. This is all helping so much. Thank yall for everything!

You could also use unhosted nested families, they'll copy and rotate as their geometry host is inside the family.
