How to create 3D solid data by boundary representation method?

To whom may it concern.

I intends to develop an interface program using ObjectARX library.
The interface program should get a function.
The funtion is to visualize STEP physical file with 3D shape data on AutoCAD
program.
(STEP = STandard for the Exchange of Product model data = Information
Standard of ISO)
- Data structure of STEP physical file is AP203 (configuration
controlled design) EXPRESS schema.
- AP203 EXPRESS schema represents 3D solid model by boundary
representation method.
- That is, the boundary representation method represents 3D solid data
by a collection of boundary surfaces.

I have already created 3D solid data using AcDc3Dsolid classes of ObjectARX
library on AutoCAD program.
But I don't create 3D solid data by boundary representation method on
AutoCAD program.
So I want to know how to create 3D solid data by boundary representation
method using ObjectARX library.
I wish to your rapid response.

Best regards,

I'm writing a LISP to create a SOLID from the boundary REGIONs (i.e. the
UNEXPLODE-problem). I'm still have troubles if there are BODY-elements, but
for a SOLID bounded by Regions or 3Dfaces mostly it will work already.
In case of interest contact me via
www.black-cad.de
