Lee,
3 Megs of RAM and a hard disk is, indeed, the minimum. You'll want that
accelerator real quick. B^) As to your other question, Imagine supports
Boolean operations, where the program detects the common parts of two
objects. You can then delete the pieces you don't want; for example,
applying the "Slice" command (that's what Imagine calls it) on an
intersecting plane and sphere will result in 4 objects: two bowl-shaped
objects (formerly the sphere), a flat circle (the part of the plane inside
the sphere), and a plane with a circular cutout (the part of the plane
outside the sphere). You can discard the pieces you don't want, and perhaps
merge the rest. You could apply this method to your imported object by
slicing it with a horizontal plane close to the top and saving the relevant
part; repeating the procedure with lower and lower planes will eventually
result in a disk subdirectory filled with the slices you want.
Other programs support this type of slicing. The keyword to look for in
ads is "Boolean".
Blaq!
