I don't believe there is one that will do this without re-tracing. One
could build something in Autocad itself using Autolisp. However, it would
have some significant restrictions and wouldn't be easy (for me at least).
A prerequisite for valid E+ input (possibly depending on choice of shading
calc) is having matched internal adjacencies. An example where resolving
this could be complicated is where two zones on adjacent floors don't share
the same footprint but overlap. New bounding elements (polylines) would
have to be created at least temporarily to represent the adjacencies.
Other things like resolving if a label is bounded by a polyline should be
At best you're looking at a hack that may get you part way to E+ geometry
quicker rather than a piece of shrink wrapped software.
