How to create 3D Solids (BOX, CONE, PYRAMID...) in VBA?

Hi!

after hours of searching and reading in Help-Files... here i am.

I want to create 3D smartsolid-elemets from a textfile in MS via VBA - because i read the datas from the elements in a ascii file.

e.g. in the Textfile ist the following code:

Element length with hight x y z oriantation(vector)

BOX 100 200 400 23,233 11,234 33,00 0 0 0

CONE 200 400 ........aso.

 ???? What is the way??? 

Many thx

Norbert
