Algorithm (Workflow)

This function, SGcableclip, is designed to create a cable clip that can be fixed at a 90-degree angle using a nail. It is part of the SolidGeometry library and was introduced in version 5.3. The function takes an optional input parameter, BDW, which is a vector containing three values: the nail length, the diameter of the cable, and the wall thickness. The default values for BDW are [3, 5, 2].

Input Parameters

• BDW: A vector [B, D, w] where:
  • B: Nail length (default 3 mm)
  • D: Diameter of the cable (default 5 mm)
  • w: Wall thickness (default 2 mm)

Algorithm Steps

1. Retrieve the input parameters using getfuncparams, with default values [3, 5, 2].
2. Assign the values from BDW to variables B, D, and w.
3. Create a square profile a with side length B using PLsquare.
4. Create a circular profile b with diameter D using PLcircle.
5. Combine profiles a and b using CPLunion with 'ontop' and 'right' alignment.
6. Translate profile b relative to a using CPLtransrelCPL with 'ontop' and 'right' alignment.
7. Create a buffer around the convex hull of the combined profile using CPLbuffer with a buffer distance of 1.2 mm.
8. Add radial edges to the buffered profile using CPLradialEdges with 2 edges.
9. Create a square profile f with dimensions based on the minimum and maximum of D and B, plus an additional buffer of 1.2 mm on each side.
10. Subtract profile f from the radial-edged profile using CPLsubtract with 'alignright' and 'alignbottom' alignment.
11. Subtract the translated circular profile b from the result.
12. Extrude the resulting profile to create a 3D shape using SGofCPLextrude with a height of 10 mm along the y-axis.
13. Create a cylinder P with diameter D and height 20 mm, rotate it by 90 degrees around the y-axis, and translate it to the origin using SGtrans0.
14. Subtract the cylinder P from the extruded shape using SGsubtract with 'centery' alignment.
15. If no output is requested, plot the resulting shape using SGfigure and SGplotalpha, and save it as an STL file using SGwriteSTL after rotating it by 90 degrees around the x-axis.
