tangent coordinate..

 

Hello Everyone!

 

Recently I have come across with an HM API i.e. '*tangentbetweennodeandline'.

Syntax for the HM API --- *tangentbetweennodeandline is 'node id line id checkpoints lineselected'

 

for using this command it asks us NODE id and a LINE id, also the checkpoint where I generally use '20' for better accuracy.

But the only thing which I don't get is what to use in 'lineselected'

 

When I use the same option through GUI I was able to select the required line, but when I want to use the above mentioned HM API it is requiring me to hardcode the line number beforehand which I'm not sure of the correct line. 

 

So I would be glad if anyone can help me with this specific problem of selection of lineselected. 

 

 

Thanks in advance.
