Trim

How to make use of the objline as a guide to trim all selected area in the drawing using VB?

Check each selected entity's IntersectWith against the "trim" line. If
it does intersect, change the selected entity's endpoint to the
coordinate returned by IntersectWith. Hardest part is to figure out
which of the endpoints [assuming a line] is closest to the returned
point.

Sound very difficult! I dun think I'm capable of getting it done!

You might want to have a look at the Curve class in
AcadX.arx. It has a method that can break entities
at one or more points, and you can use it to emulate
the TRIM command. After breaking, you can erase any
objects that are not inside of your trim boundary.

Does it mean that I need to know exactly the coordinate of the line that is intersecting with and assign an objline to that line on the drawing in order to adjust the endpoint? Possible to use selectionset to select a number of vertical objline that are insecting with a single horizontal line?
