If a line coordinate touches a circle entity of a block- say yes

[Qonfire]

Thats good to know, But I know there's more to it that just T or nil, can you show or descrbe for us the whats going to happen next after the test?

 

I'm trying to easy up the boring process of drafting a sprinkler system.The bulk of these plans layouts, are sprinklers and pipes. (blocks and lines)

So after placing sprinklers,there will be pipes drawn, than pipes will be trimmed within each blocks,than i want cad to see if its a pipe (only line segment) -->put dimension start to end point, if line (pipe)intersects with sprinkler(block), start point of line to center point of block.

 

For now, i just collect pieces of how to get to it.

Merci
