.ifc to .dwg top view objects not visible

[krohlfs]

I used AutoCAD MEP 2014 to open an .ifc file, importing it into .dwg.  This particular file is a Structural Joist file.  When I open the .dwg file, the joists are not visible in Top View.  If I look at the objects at any other angle, I can see they are there, they are just not visible in Top View.  How can I fix so I can complete a set of drawings?  

Thank you!

Post the IFC file.

I do not own the file, so unfortunately I cannot post it.

Post a dwg with a couple of these objects that exhibit that behavior.
