I want to get the XYZ coordinate point in sketch segment (a 3DSketch Line)
but when i'm using GetSelectionPoint() it will always return the start point in the sketch segment (no matter part of the line, except end point)

how can I solve this problem?

and another question is

I want to use CreateBodyFromCyl() while I draw a 3DSketch Line.

it will display cylinder body with direction and distance snap with the line (after draw start point (first time)) and delete the cylinder after finish drawing a line (work as a preview).

can anyone give me an idea?

thanks you.
