Revit :: Why Can't See Wall Sconces

Short story is I made a wall sconce from scratch but I can't see the symbolic lines in my ceiling plan in the project.
 
I needed a linear wall sconce for a client presentation based on one of theirs already installed.  The manufacturer doesn't provide BIM for this model so I had make my own.  I haven't bothered with photometrics.  At this point all I need is a placeholder for the ceiling plan and a 3D model for a hidden line view. I used the wall based light fixture family.  There was a plane elevation but no apparent parameter so created one and called it 'mounting height'.  After about ten minutes of modeling (and over an hour of tedious aligning, dimensioning and locking of the sketches to keep the model from distorting with changes in wall thickness) I opened the ceiling reference level plan and drew some symbolic lines to represent the fixture on the ceiling plan in my project.
 
Here's what happened.
 
The symbolic lines for the CPRL (Ceiling plan in the family editor) are also visible in the FPRL.  I don't know why this is and there doesn't appear to be a way to hide them in just one plan.  I suspect it's because both are at the same height (the reference level.)  I tried changing the working plane before drawing the symbol lines to another plane above the reference level and out of its view range but it had no effect.  I can still see them in the floor plan.When I loaded it into the project nothing appeared and I got the message about 'no elements are visible because yada yada'.  The symbolic lines didn't show up at all.  I checked the detail level and that wasn't it.  As far as I can tell the view range for the CPRL and the RCP in my project are the same.  They don't show up in the project floor plan either.  The sconce is visible in 3D views so it's definitely in there.  I tried monkeying with the height of the symbolic lines like I stated in part 1. but it had no effect on there visibility.  Symbol lines are visible in other families so it can't be an issue with visibility overides.In my project I noticed there's a parameter for the fixture called 'Elevation'.  Changing it moved the fixture up and down on the wall.  Changing the 'mounting height' parameter in the project had no effect!  This parameter worked fine in the family editor.  Playing with the 'Elevation' parameter and the cut plane elevation brought the symbolic lines into view.  Apparently the symbolic lines are only visible when the cut line is passing through the sconce.  Unfortunately my sconce needs to be mounted at 6 ft and my cut plane is at 7'2 to avoid cutting doors and windows.   How do get these symbolic lines to display?
