SGchamfer

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - SG/Solids
Introduced first in SolidGeometry 4.1, Creation date: 2017-08-16, Last change: 2025-09-14

chamfers the edges of a 2.5D Solid Geometry

Description

ATTENTION reduce radius first if the result is unexpected, start with .1
Optimized in Dakhla, Marocco. It does not returns as perfect edges as SGofCPLzchamfer! Used first with negative values by Samuel Detzel!
if r>0; r must be larger than abs(ph)*1.5
ATTENTION: If r is reduced automatically by tangentcirc, ph can be only r/1.5, or r must be zero!

Syntax

SGN=SGchamfer(SG,[ph,ed,r,stype,posit,shape,holeph,ed,r,stype,posit,shape,hole])

Input Parameter

SG: Solid Geometry with just two different z values
ph: edge/phase size default is 0.3; [r z], [r zs ze] is also valid
ed: curved edges; default is true
r: radius for radial edges; default is ph*1.5
stype: default is 'angle'; see SGof2CPLzheurist
posit: 'both', 'start', 'end' or calculated from ph
shape: PL or 'line' (default), 'circ', see PLchamfer for all values
holeph: "norm", "outw", "hole", see CPLgrow for all values

Output Parameter

SGN: Solid with chamfered edges
