Select polyline vertex coords by number

Recommended Posts

In AutoCAD, by selecting a lwpolyline and then properties we can select a vertex number and it's corresponding coordinates, is it possible to extract this information using LISP?

 

In other words, can I select the lwpolyline and use an arbitrary number to go straight to the required vertex or can I only increment through? I can get the first or the last point using vlax but can I go to vertex 6, for example?

 

It would be easier if there were a vlax-curve-getpoint(6)
