finding comon parts of two 2d objects ??

[lispino]

1º. Is it possible to select 2 diferent blocks (or multiple object selections) and then create on other with the comon parts?
(the result doesn´t have to be in the same kind of objects,
I just want to find something that "looks" like the intersection of both)

2º. Or even draw a point in the intersection of two (or more) selected lines, arcs, plines....?

Anykind of information would be usefull :]

Haven't tried it on blocks, but the "intersect" command will create a solid from intersecting solids, or a create a 2D object from overlapping regions.

Solids and regions are in fact easy tasks,and i've tried to use the same commands with no succes.
my real problem is with more "complex" objects like for example: lines ????

In a simple problem:
I have 2 parallel lines with diferent length, one over the other. Can I, with a lisp rotine, create one other object or objects representing the comon part of both lines ?

At this stage I am wondering if i need to find the mathematical equation of both . . . but still wondering
if there is one other slightly easier way . . . :[
