CPLfischertechnik
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - CPL/Closed Polygon Lists
Introduced first in SolidGeometry 4.3, Creation date: 2018-10-31, Last change: 2025-09-14
returns the most common CPL for the design of fischertechnik compatible connections
Description
The stones have a width of 15 x 15 x 15 mm
The buttons have a height of 2.5 mm, a width of 4 mm at the head and 3 mm at the foot.
The distance between the rails is therefore also 15 mm.
The rods have a diameter of 4 mm.
The drill holes have a distance of 10 mm
The holes are cut with the button foot widths
The buttons were initially cut circles and have changed to swallowtails or today V-lips

Syntax
[CPLL,CPLI,CPLC,PL3,PL4]=CPLfischertechnik([tol,gb])
Input Parameter
tol: | | [tolerance between the lines CPLL and CPLI[a |
gb: | | length of contour; default is 15 mm |
Output Parameter
CPLL: | | Line to create a blade or concave contour (rail, blade) |
CPLI: | | Line to create a convex contour (knob) |
CPLC: | | Line to create the concave contour for the axle |
PL3: | | Line to create the concave contour for 2 axles |
PL4: | | Line to create the concave contour for 4 axles |
