Thanks for your reply.
How to use sendcommand for crossing option as the crossing option does not accept co-ordinates. Instead it asks to pick a point on screen.I have attached a drawing, I have tried many ways to get the final output as you seen in the drawing but i cannot.
Maybe an idea to get the objects, try to .IntersectWith and manually replace the last coordinate with the InterSect-Point? The last coordinate can be determined by the Clicked Points (I think you use GenEntity?)
Util..getentity Object1, PickPoint1
Util..getentity Object2, PickPoint2
IntersectPoint( [0-2] ) has the coordinates...
