fourBarposelayering
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - 4Bar/Linkages
Introduced first in SolidGeometry 5.1, Creation date: 2022-01-25, Last change: 2025-09-15
Creates the layering and the shaping of all 8 elements of a Fourbar linkage
Description
Afterwards a function such as SGofCLLL to implement the assembly method.
The process:
Posesample => Posedefiniton
fourBarposesyntheses => compute fourbars with 1, 2, 3 pose synthesis
fourBarposeplotsolution => plot or animate solutions
fourBarposesortsolution => sort and select solutions
fourBarposelayering => layer and compute shape
fourBarCLLL2SGdesign => Design for assembly and 3D print

lay: | | default is [0 2 1 1] |
Shape: | | "A*" (default) or "Bezier" |
"debug": | | covers the crank behind the effector |
"hide": | | [angle-offset angle-range]; default is [0 360] |
"wlim": | | |
Output Parameter
LLLM: | | Contour Link Level Layering ==> fourBarCLLL2SGdesign |

Examples
PS=PosesampleWalk
PS=fourBarposesyntheses(PS,[1 2],[15 3 3],'','','isrot,break coll CPLW CPL0'); % 200 solutions
PS=fourBarposesyntheses(PS,[1 2],[20 2.5 2.5],'','','isrot,break coll CPLW CPL0'); % 317 solutions
fourBarposeplotsolution(PS,1);
fourBarposesortsolution(PS,'crank-length',[10 inf],'coupler-length'); PSX=ans;
fourBarposelayering(PSX,1,[3 1.6 3],[0 2 1 1 -2]); CLLL=ans; % CPLW must be -2
