returns the SG for a scrat protector of a specific Bauhaus style chair

Description

programming time was just 10 minutes. Many chairs from the Baushaus school are made of leather and stainless steel profile tubes or chrome-plated tube profiles. These easily scratch a wooden floor. For this reason, a scratch protector is designed here for a square profile

Algorithm (Workflow)

This algorithm is designed to create a scratch protector for a specific Bauhaus style chair. It is a parametric design function that utilizes several geometric operations to achieve the desired shape.

Input Parameters

The function does not take any direct input parameters from the user. Instead, it uses predefined values and functions to generate the geometry.

Algorithm Steps

  1. Define the diameter D as 25.4 mm.
  2. Set the width w to 2.4 mm.
  3. Use the function slfit('t') to obtain a value slt, which is used later in the algorithm.
  4. Create a complex polygon CPLA using the function CPLofPL with a square defined by the dimensions [D D/2+w/2]*1.41+2*w.
  5. Create another polygon CPLB using PLsquare([D D]+slt).
  6. Transform CPLB relative to CPLA using CPLtransrelCPL with a rotation of -38 degrees (converted to radians) and align it to the bottom with an offset of -w.
  7. Subtract CPLB from CPLA using CPLsubtract.
  8. Generate a solid geometry SG from the modified CPLA with a height of 40 mm using SGofCPLz.
  9. Plot the complex polygons CPLA and CPLB using dbplot with the 'cont' option.
  10. Write the solid geometry SG to an STL file using SGwriteMultipleSTL.
