Posted - 08/10/2017 : 1:07:03 PM Hi everyone! I need to find the point of intersection of multiple 3D vectors as in the attached image. The intersect option under 'Gadgets' tab isn't working. I think it is only valid for 2D lines. Kindly help.

In 2D, line segments intersects easily, but in 3D two lines cross each other very rarely (especially with the finite precision of computing). Anyway, you can try the following procedure:
1) Organize your XY data as separate datasets (one column two rows for a line segment). 2) Make Line+Symbol plots from these datasets, and gets all intersection point using the Intersect gadget. 3) For each intersection point, calculate the interpolated Z values of the corresponding 3D line segments. 4) If the two Z values are within a preset tolerance, accept them as intersected.
Hope this helps to advance your work.
