How to measure the intersection.

I have two points 2d.

'((x y) (x y))

I choose 3Dpolyline

(entsel)

How get interswction point (3Dpoly and "line")?

The easiest way to find this intersection is to use the apparent intersection snap.

 

If you want the point to be on the 3d polyline you need to select the 3d polyline first then the line.

 

Otherwise it wouldn't be too difficult to write a lisp that asks the user to select a line (obtaining the two 2d points)

and then asks the user to select a 3dpolyline and return the intersection of the two.

 

What is it that you are looking for?

I use the method described above, just be aware that the "apparent intersection" is calculated based on PROJMODE (view vs current UCS)
