Solid Geometry Cap for an EUTRAC 3Phase electric rail

Description

A student of Josef Albers (Square) was Otl Aicher (13.5.1922) who designed or used, among other things, light strips. In general, they are extruded aluminum strips with which several power lines and data buses can be transported. A concept that can also be used very well in robotics. The company ERCO has cooperated with him. Other suppliers of the same technology besides ERCO are Eutrac, Staff, Global, Powergear, Ivelva, Unipro, Stucci and others.

Algorithm (Workflow)

This algorithm is designed to create a solid geometry cap for an EUTRAC 3Phase electric rail. The function SGEurtraccap generates a 3D model of a cap with specified dimensions and properties.

Input Parameters

w: Width of the cap, default is 36 mm.
h: Height of the cap, default is 32 mm.
l: Length of the cap, default is 40 mm.
s: Slot size, default is 16 mm.
t: Wall thickness, default is 1.2 mm.

Algorithm Steps

Retrieve function parameters using getfuncparams, with default values [36, 32, 40, 16, 1.2].
Create a square profile using PLsquare with dimensions [w, h].
Generate a radial edge profile using CPLradialEdges from the square profile.
Extrude the profile along the z-axis using SGofCPLz with length l, wall thickness t, and floor thickness t.
Subtract a box from the solid geometry using SGsubtract with dimensions [s, s, l+w+h], aligning it at the bottom and in front with specified offsets.
Write the resulting solid geometry to an STL file named 'EUTRAC' using SGwriteSTL.
If no output is requested, display the geometry using SGfigure and SGplotalpha with a green color.
