FSfeature

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - FS/Feature Surfaces
Introduced first in SolidGeometry 5.1, Creation date: 2021-07-15, Last change: 2025-09-15

Selects features surfaces based on

Description

There are several functions for the selection of surfaces, features, and frames
FSofSGnormal - uses a normal vector for the selection
FSselect - should simply select surfaces out of a larger set of surfaces
FSfeature - should return properties of different data types
see also all SGTset functions
=======================================================================
The 3rd of a set of functions aimed directly at the analysis and formal specification of surfaces. This is necessary to give a clear structure to the formal addressing of surfaces. Concept similar to TofSG
1) FSofSGnormal - FIL wrt to a normal vector
2) FSselect - FIL as selection based on features
3) FSfeature - Different data types wrt to feature request

Feature request:
"cp" Center point
"ez" Normla vector
"area" Area size
"numholes" Number of holes
"T" Center Frame

Example Illustration

missing image of FSfeature(SG,FIL,feat)

Syntax

F=FSfeature(SG,FIL,[feat])

Input Parameter

SG: Solid Geometry
FIL: Cell list of facet indices
feat: feature request string

Output Parameter

F: Result as cell list; scalars, vectors, frames, etc.

Examples


load JACO_robot.mat
FSselect(JC0,[1 0 0],0.4,'areamin',100); FIL=ans;
FSfeature(JC0,FIL,'numholes'); cell2mat(ans)
