TofSGfil

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - FS/Feature Surfaces
Introduced first in SolidGeometry 5.5, Creation date: 2025-08-04, Last change: 2025-09-15

Provides the frame for a feature surface that is passed as a face index list.

Description

This function is nothing other than CPLofFS or CPLofVLFL, but cannot be found under this name if you are not interested in the contour but only in the frame in combination with FSselect.
Be careful, since there is no guarantee that T shows in the direction of the original surface. Consider TofSGFSselect for that.[spchk]

Syntax

[T,CPL]=TofSGfil([SG,fil])

Input Parameter

SG: Solid Geometry
fil: Facet index list of a closed surface

Output Parameter

T: Coordinates frame of the facet index list
CPL: Boundary contour of a planar feature surface

Examples


load JACO_robot.mat % or loadweb if not loaded already
TofSGfil(JC0,FSselect(JC0,[0 0 -1],'front',-1));
TofSGfil(JC0,FSselect(JC0,[+1 0 0],'front',-1))
TofSGfil(JC0,FSselect(JC0,[-1 0 0],'areadescend',1))
TofSGfil(JC0,FSselect(JC0,[+1 0 0],'areadescend',1)) % frames shows in the right direction
TofSGfil(JC0,FSselect(JC0,[+1 0 0],'areadescend',2)) % frames shows in the wrong direction
