What prop to use for shapefile export of 3d breakline plines?

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.

note, it is not the elevation property. That is only for lwpolylines (flat with one elevation)...

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

BTW you can only export simple AutoCAD objects none of the Civil3D objects
get exported. Also if it's only a surface export it to DEM, 3D Analyst can
work with it.

MY GOSH! Worked perfect, if you only knew what a big help that is. I owe you buddy.

I have been dealing with the slow speed of direct dwg import for three weeks now.
The ESRI forums are practically silent to my posts a week ago.
I think ESRI should include a link to these groups in their forums.

Pabst Blue Ribbon.....

I used to post on "those" forums years ago, trouble is the pepole that need
to ask can't get there or don't know about them and the ones that do post or
read them are ........... amm. lets just say either a DeanS, TonyT or
ClintonG type of poster with emails ending in e$ri.com. There are some good
posts now and then but you need to really search to find answers then hope
it applies to the version and module of the software you are using.

Just a FYI - I attended a dinner seminar by the local ASCE chapter that
highlighted the local watershed studies
that they performed for a local agency. The had LIDAR data for the
county and to create HECRAS sections, they had to limit the TINs in
Arview to less than 7 million points or they crashed the software.

They were able to get good watershed maps using raster elevation models
at about a density of 2.5 million points.

I would assume that getting large datasets like that are tough in a 32
bit environment.
