Lwpolylines

Raam Finzi

I'm trying to extract the coordinates of vertexes of a Lwpolyline. Up to ver 7, ' I could extract the coordinates, including  the elevation, for each vertex. It was kept under group code 10. Now I found, that only the y,x Coordinates are kept under group code 10. What is the code for the elevation of each vertex ?

group code 38 holds the elevation of the entire LWpolyline and appears only once.

LWpolylines are always planar (flat), unlike 3dpolylines.

 

(if the LWpolyline is angled with respect to the Z axis,

then the group code 210 holds what is called the "extrusion" direction,

which is a 3D vector normal to the plane of the LWpolyline)
