Need to find line that intersects with my perpendicular line

[Proctor]

Hello: I'm working in AutoCad .net api:

 

I have a line (see black line in pic) and I find it's perpendicular line (see red line in pic) and now i want to find the line that intersects w/ this red line (see blue line in pic).

 

I know about the intersectWith method, but this won't take a collection of lines so i can see which line in the collection it intersects with so i'm wondering if i need to loop through my collection of lines....or if there's another way.

 

thanks

A looping test would be the most straightforward method of finding an intersecting pair. Depending on the circumstances there may be some optimization available with selection set filtering . . . . to avoid testing against every entity in the database.

Hi SEANT: Thanks for your reply. I will go ahead and loop through my selection set of lines then.

 

thanks again,
