PLofVLplaneprojection
by Yilun Sun, SG-Lib Toolbox: SolidGeometry 5.6 - PL/Point Lists
Introduced first in SolidGeometry 4.9, Creation date: 2020-01-13, Last change: 2025-09-14
main axis projection of a vertex list along the largest dimension of a normal vector
Description
This function was written by YILUN Sun on 2018-08-16. It uses the effect that the max function returns the first occurance index of the largest value of the operand.
This is not a true to scale function since it is a axis projection !!!
This function can easily extented to more than 3 dimensions.
