[cad-linux] Re: the parametric project

Eric,
you are most welcome to use the kosmos site for RFC's, design documents
whatever you see fit. 

The thread last week was intense and then fortunately lost some steam. 

I have started to think about parametric geometry. This is *not* an
easy task but I believe to have a first simple prototype going. 

It is a model where geometrical entities are considered dependencies
and they are defined by relations to one other geometrical entities. As
an example a point is defined through it's relation to another point. 

P1 <--- P2 

P2 relates to P1, if P1 moves so does P2. Very simple but works. The
code for this is in the latest upload on kosmos.sf.net.
