Hans,
I tried:
% redraw line
path q;
q:=pathpart pic;
drawdblarrow q withcolor blue;
But it drew the clipping path. I wanted the part of the path inside the
clipping path.
Am I missing something in your directions?

This works fine. However, what I need to do is somehow clip the path

variable Q. That is, I need to cut off the parts of the path P that
lie outside the bounding box
cpath:=(-5,-5)--(5,-5)--(5,5)--(-5,5)--cycle and store the clipped
path in the path variable Q. The difficulty is I have no advance
knowledge if the path P lies entirely inside the bounding box or if
it escapes through one of the sides.
it all depends on what you want to do further on;
- you can do some cutbefore and cutafter trickery, i.e. determine
intersectionpoints with the edges of the bbox and do some cutting
- if you just want the path back .. just ask for "pathpart pic"
