Hope someone can help with the following:

I have a historic building with ornate plaster covings.

I wish to model this ideally based on a profile rather than a mass with the profile following a path (Not a wall sweep as the same wall type with different coving profiles)

Also is it possible to then do a quantity takeoff of the profile as a surface area? This is because the covings require stripping back with poultices which is labour intensive.

The issue I have with using a mass as a profile is that this will take the full surface area, not just the visible face area which a profile will give me.

Photo enclosed

Trust this makes sense.

I had to look up coving, in the US, in the interior, we call it crown moulding and on exterior, cornice moulding. 

 

A close up view would have helped, your image is too grainey whenn zoomed in.  When I do, I think I see standard moulding shapes plus dentil moulding shape (see first image). I may also see some egg and dart moulding. (see second image)

 

I have done this kind of modeling on exterior cornice work that had dentils.  Because we were going to use standard wood moulding, I used a series of our standard library moulding profiles as sweeps for the simple profile shapes.  (You could do a single profile shape to create the bulk of this area rather than 4-5 individual profiles.)  Then I added a line based, repeating element for the dentils (egg and dart couild also be done).  (A couple of you tube videos here: 

https://www.google.com/search?client=firefox-b-1-d&q=revit+line+based+repeating  )

These line based items will not miter in corners so you will need an inplace element there.

 

You want the surface area of these intricate profiles?  No way that I know of.

I have created an inplace mass as a profile, offset the profile and then extruded to path. I then divided the m2 area by 2 to give the visible surface. This is sufficient for take off purposes and costing. As these are required to have the paint stripped back to original plaster and at about £ 200/ m2 to strip using poultices and fully attendant specialist to ensure the poultices dont eat into the mouldings its an expensive task. I have approx 500m2 of coving/ cornice mouldings to strip on this project plus about 2000 linear metres of plaster wall panel mouldings. The mouldings are interior plaster from the 1880's in a historic building here in the UK. As mentioned it would be easier if I could extrude a profile to pathe rather than using a wall sweep.
