Algorithm (Workflow)
This function, SGofR12, is designed to create a solid representation of a link with minimal dimensions for assembly methods. It is part of the SolidGeometry library and was introduced in version 5.1.
Input Parameters
- R12: A vector containing the dimensions of a link. Default values are [6, 2.5, 6].
- DIN: A boolean indicating whether to use the SGdesignDIN912DIN985 function. Default is false.
Output Results
- SG: The solid representation of the link.
- RMHL: A vector containing the minimal dimensions [Rmin, M, Hmin, Lmin].
Algorithm Steps
- Retrieve the R12 and DIN parameters using the getfuncparams function. Default values are used if not provided.
- Extract the individual dimensions Ro, M, and H from the R12 vector.
- Calculate the initial length L as 1.5 times Ro.
- Set a minimum wall thickness of 1.25 mm.
- Use the DIN985 function to adjust the M dimension and obtain the TL vector.
- Calculate the minimal radius Rmin, length Lmin, and height Hmin based on TL and wallmin.
- Update the RMHL vector with the calculated minimal dimensions.
- Ensure Ro, L, and H are at least as large as their respective minimal values.
- Create a profile PL using the PLcircleoval function with Ro and L.
- Generate the solid SG using the SGofCPLz function with PL and H.
- Set the bottom and front transformations of SG using the SGTset function.
- If DIN is true, use the SGdesignDIN912DIN985 function to design the solid H, N, and S. Otherwise, create a cylinder N with SGcylinder and set its transformation.
- Subtract H and N from SG using the SGsubtract function with alignment options.
- If no output is requested, plot the solid SG using SGfigure and SGTplotalpha functions.
