CVLofSGfi
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - CVL/Closed Vertex Lists
Introduced first in SolidGeometry 5.1, Creation date: 2021-03-20, Last change: 2025-09-15
returns from a (interactively selected) facet index the Contour and Transformation matric
Description
This function expects a facet index as input parameter and returs T at the facet position.
CVLofSGT -requires SG.TFil of T (SG.TFil <== TR3mountingfaces, SGTui)
CVLofSGfi -requires only fi
CVLofSGTFS-requires only T - detects drilled surf not bore hole surf
Currently, a renewed set of functions based on the relation of surfaces and frames is emerging. Since part of the "language syntax" is hidden in the function names and the complexity of the geometric language is only worked out over the years, and the syntax also changes slightly, it may be that there are functions with similar names that do different things and functions with different names that do similar things. This will have to be corrected in later years, when an overall picture emerges.

Syntax
[CVL,T,CPL,cp,fi]=CVLofSGfi([SG,fi,sw])
Input Parameter
SG: | | Solid Geometry |

Output Parameter
CVL: | | Closed Contour in Space |
T: | | Transformation Matrix (at position of fi) to create CVL from CPL (is ona surface) |
CPL: | | Planar Contour |
cp: | | center points related to CPL |
fi: | | facet index if selected interactively |
Examples
CVLofSGfi(YKShoulder); % Select Manually
CVLofSGfi(YKShoulder,15432); % Select by fi
