Actually, that is only half true. When you draw the structure, it is
indeed drawn in 2D, but you can then minimize the structure in 3D to
generate the 3D coordinates. (Choose Edit -> Clean -> 3D -> Clean in
3D.) You can also generate a series of conformers of the compound
and import the 3D coordinates of one conformer back into the 2D
viewer. (Choose Edit -> Clean -> 3D -> Select conformers.) The
structure can be exported in any number of formats. It's a really
powerful applet. Try it and see.
I concur with the comments on ChemDraw and Chem3D. Asking
Cambridgesoft to add a feature is like asking God to help you win the
lottery. It might happen sooner or later, but probably not, and even
if it does, your request probably had very little to do with it.
