On the mapexport dialog, option tab, click on driver options then select 3D
shape files. See if that works for you.

I want to export my drawings with 3d plines to shapefile for use in ArcMap
to make surfaces (tins) with 3D Analyst.
I am experimenting to see if it handles large datasets better then C3D -
which everyone says it does so far.
Pulling features in directly from the dwg is proving to be super slow, as if
the ESRI tools are not good at reading
larger drawings (40 mb). I wait for two minutes to just see the feature
classes available, then several more for the
import. The ESRI tools import a shapefile much faster, so its worth the
export step.
When making the shapefile, you must tell acad what props to export, so ESRI
tools can use one for the Height Source.
Nothing is working for 3d lines though. I tried every combination I could
get to export, but the shapefile shows as 2d
in ArcScene and has not useful field to set for Height Source.
Is there some property I need to export, and maybe rename the export field
to less than 10 characters? I know
shapefiles are negatively sensitive to long field names.
Any help much appreciated.
