Algorithm (Workflow)
This function, VLFLsnapfit, is designed to generate a 3D model of a snapping hollow axle. It takes several input parameters and returns a vertex list and a facet list, which can be used to create a 3D printable model.
Input Parameters
- RI: Radius of the bore.
- RA: Radius of the flange.
- D: Width of the axle.
- Hf: Height of the flange.
- H: Height of the bore.
- sh: Size of the hook.
- Hh: Height of the hook.
Output Results
- VL: Vertex list, which contains the coordinates of the vertices of the 3D model.
- FLW: Facet list, which defines the faces of the 3D model using the vertices from the vertex list.
Algorithm Steps
- Define the snapping fit geometry using the input parameters. This is done by creating a list of points (RL) that outline the cross-section of the snapping fit.
- Call the function
VLFLrotsymRLn with the defined geometry (RL) and a rotational symmetry parameter (20) to generate the 3D solid. This function returns the vertex list (VL) and the facet list (FLW).
- If no output arguments are specified, the function will automatically plot the 3D model using
SGfigure and VLFLplot with a specified view angle.
The function is part of a library for modeling procedures and is used for the automatic construction of 3D printable mechanisms. It was introduced in SolidGeometry 1.1 and is referenced in various other functions within the library.
