Fireproofing on beams in sections

One major lacking feature of Revit is the inability to easily place fireproofing in sections.  Typically to increase the level of detail in a view, detail components are placed on top of model components.  The detail components then give a higher level of detail to the view, one with we are accustomed to seeing.

What do you do to place fireproofing around beams in the section views?

I'm sure many different people have many different ways of accomplishing this.  Some create groups of drafting lines which are sized to the beams they use in their project, the group can then be placed over all the beams of the same size. (you need to create a different group for each size of beam however).  But how do you go about drawing the fireproofing in the first place?  You probably use drafting lines, drawing the arcs one at a time with 3 clicks per arc.

I learned this tip after doing some research, because I was convinced that there was a better way to do this.  One way to inherently draw arcs is to use the revision cloud tool.  (we can talk how this is inconveniently different from the ACAD version later)  Act like you are drawing a revision cloud around the beam, but draw it as if you were drawing the fire proofing (create really really small arcs).  Since this tool creates 2 arcs with two clicks, it can save you considerable time and effort drawing all the arcs.

After you finish drawing the arcs, Don't click the finish button.  Instead select all the arcs you just drew and copy to your clipboard.

Exit out of the command by hitting the red 'X' button and confirming you want to exit and lose all changes. 

Now go back to Modify|Clipboard|Paste aligned to current view and all the arcs will show up again in the view exactly where  you had drawn them in sketch mode for the revision cloud.  They are now drafting lines.  You will most likely need to change the drafting line to another style more appropriate to the view.  Since the lines stay selected as soon as you paste them, its as easy as going to the properties and changing the line style.

With all the arcs selected, you can turn these into a group (maybe name it something related to the beam size the fireproofing matches) and it will be easy then to place on other beams in the view.

Wasn't this much simpler than drawing all those individual arcs?  You just saved yourself some valuable time doing something very monotonous!
