Algorithm (Workflow)

This function, SGdesignIgusdragchain, is designed to create the subtraction and supplement solids for fixing an Igus drag chain. It is part of the SolidGeometry library and was introduced in version 5.2.

Input Parameters

M: A vector of parameters, defaulting to [2 5 2 7]. These represent:
- M(1): Screw type, specifically M2 DIN 7991.
- M(2): Distance, set to 5.
- M(3): Pin diameter, set to 2.
- M(4): Pin length, set to 7.

Output Results

Nsub: Subtraction solid (green).
Nadd: Supplement solid (yellow).
S: Screw (magenta).
AParts: Parts list.

Algorithm Steps

Retrieve function parameters using getfuncparams, with default values [2 5 2 7].
Define offset ol as 0.1.
Retrieve slot fit parameters slt and slc using slfit for 't' and 'c'.
Create a base solid geometry SG using SGbox and retain it with 'F'.
Create an Igus geometry IG with dimensions [10 7 2] and adjust its vertices.
Create a subtraction cylinder Psub with radius M(3)/2 + slt and height [-ol M(4)+slc], then translate it.
Call SGdesignDIN7991BushingE to generate initial solids and parts list.
Concatenate Nsub with Psub to form the final subtraction solid.
If no output is requested, plot the geometries using SGTplotalpha with specified colors and alignments.
