Designs a 4bar-Linkage as solid geometry

Description

Since it is now clear to me, that 4 joint coordinates defined a unique 4bar-linkage, it is possible to design a solid for

Syntax

SGall=SGfourbarlinkageA0B0DIN912985(CPL,[wlim,R12o,PS,MM,MPL,FIX])

Input Parameter

CPL: [A0; B0; B1; A1; [GPLA GPLB]] to define the 4bar linkage | Nr of PS.solut
wlim: angle limitatins; if empty the full intervall is used
R12o: Outer an inner radius for linkage [Rout Rin]; default is R12ofCPL
PS: Pose including fields CPLE
MM: [metrix diameter metric length overlap; default is [2.5 6 0]
MPL: Rack assembly point to add
FIX: fixation method '985' or 'bush'

Output Parameter

SGall: {SGC,SGE,SGS,SGG,SG0}
