Surface Clicking and Normals

Clicking on a 3D model when the tool is active prompts the software to look at the exact triangle on the 3D mesh under the mouse. It extracts two main pieces of data:

1.The Position (X, Y, Z): The exact location in millimeters relative to the object's reference frame.

2.The Normal Vector (I, J, K): A directional vector that points 90 degrees from the surface at that specific spot.

The add-in uses this normal vector to determine how a tool should approach the object.
