Urgent!!! intersection problem

Urgent!!! intersection problem

Urgent!!! intersection problem

(OP)
Hi
Well I have the equation of a line passing through two nodes and also have a free surface model which i have imported by .model format from a CAD software(CATIA).I want to know at what coordinate this line intersecs the surface.Does ABAQUS CAD  module has the ability to do that?if not is it possible to do this by python scripting?
thank you
Dariush

Dear Yoman
Here 's my solution.
First i found two points on eachside of the surface using the equation of the line passing through two nodes.(I wrote the equation base on an arbitary parameter 't')Then by passing a wire polyline the intersection vertex were created.Now it is possible to create a Datum point on the vertex and ask for the coordinate and save the values.At the end i deleted all points and wires created in order to save memory.I needed to find the intersection for all 3000 pair of nodes so i wrote a python script to do this in a loop.
Does anyone has a better idea?I do appreciate your comments.
Dariush
