+Project Point On plane
+======================
+
+Description
+-----------
+This node takes a point and a plane and returns information about the projection of this point on that plane.

+Illustration

+.. image:: images/project_point_on_plane_node_illustration.png
+
+Inputs
+------
+
+- **Point** - The coordinates of the point that will be projected.
+- **Plane Point** - A point on the plane.
+- **Plane Normal** - The normal of the plane.
+
+
+Outputs
+-------
+
+- **Projection** - The coordinates of the closest point on the plane to the input point. Mathematically this point is the point that makes a perpendicular line to the input plane which also makes a line that is parallel to the plane normal.
+- **Signed Distance** - It is the shortest distance between the input point and the input plane, Which is also the distance between the projected point and the input point. Although distances can't have a negative sign, this output could have a negative sign if the point lie below the plane while positive if above.
