Hello!

I want to connect some block programatically. The simplest way for that is to add_line by points but when i add line by that way i encounter problem when points lay on existing line. In that situation two different lines are linked. Is there any way to check point to laying on existing line?

If you need to connect from a to b and a to c, can't you run add_line(a,b) and add_line(a,c) to achieve it?

It works! Thanks!

I sure that I have try that way some times and that doesnt work because one of port has a connection.

Write answer please. I will approve it.

Checking whether a point lays on any existing line will be very difficult. The answer to the OP's question seems to be utilizing add_line() in a different way. Rather than specifying multiple points in one add_line() to achieve connecting multiple ports, calling add_line(SourcePort, DestinationPort) multiple times seems to meet the need.
