In the case of solids that retain the entities used to define them, those
entities are stored in the solid's definition as ACIS objects. Even if you
took the standard approach/kludge of recreating the object from scratch
(which is often done with composite solids created from boolean operations),
there is still the problem of not having the original defining entities in a
usable form.
The API support for 3D in AutoCAD is bare-minimal, or in practicle times,
nearly useless. It seems to be carefully designed to prevent it from being
used to create solutions that are competitive with other Autodesk products,
like Inventor.

AutoCAD 2010 - Has anyone had any experiance of programatically manipulating
a Surface entity?
I know how to create one in Autocad, and then when you select it, you get
some grips which allow you to manipulate/change it, in real time.
But how do you do that programatically? IE - if i create a SweptEntity
surface, from a circle and a spline, if the spline changes in any way, I
want to sweptsurface to change in response, without having to re-create it.
Cheers!
John.
