SGgrow

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - SG/Solids
Introduced first in SolidGeometry 2.4, Creation date: 2015-08-03, Last change: 2025-09-14

returns the same solid by with increased dimensions

Description

grows a solid by adding the vertex normal vector to the vertex coordinates multiplied by a factor d. ATTENTION, The MATLAB-original vertex normal calculation is not always correct. Therefor in this function we used a different methods with some side effects too.
SGgrow function is perfect to analyze the correctness of Surface Solids

BTW: CATIA LIMITS THE SPATIAL RESOLUTION TO 0.01mm, ie. 1e-2

Output Parameter

SGN: resulting solid geoemtry
