Questions about DrGenius

Hi,
I am a new potenital  user of DrGenius, and I recently posted a mail in 
French...apparently english is better as a communication langage on this 
mailing list. Sorry in advance for my poor english...

My questions are:

1) Is there any "trace" tool available on DrGenius ? I am speaking of a tool 
which alllows to keep the trace of the different positions of objects when 
(for example) a free point is moved with the mouse. Example: a half disk is 
depending of a free point moved on a segment, and one would like to see the 
surface covered by the disk when the point is moved.

2) If not yet existing, does anybody has an idea of the way such a "trace" 
tool could be created ?

Thank's in advance,
	F.Baldit

PS: Also: is there any "3D" version of DrGenius ? (in order to do 
3-dimensional geometry).
