Topic: Howto cutting all out or in a rectangle ?

[MarioR]

Hello,

i have an complex drawing and now i must cut all out of an rectangle (i have min-max-box).
On manual work i use the Civil/Map-command "MAPTRIM".
But i will cut the entities in c# code.
Exist a function for this or must i use the intersection for all entities?

regards Mario

If you want to write a function like that you must indeed find the intersection of all the objects you select. Not all entities in the drawing because you can make a selection of your rectangle.

Be aware you need to create functions to explde blocks and blocks inside blocks, dimensions, circles (that become polylines after trimming), etc.

There is a lisp by Joe Burke that does this trick. It is lisp but works well (except 3D polylines I remember).
