returns a solid geometry for a snap rivet
Description
mainly the same as VLFLsnaprivet of 2013 July.
If there is no force specified, the snap ribved is designed only wrt geoemetric conditions

Algorithm (Workflow)
This algorithm is designed to create a solid geometry for a snap rivet using the function SGsnaprivet. The function takes several input parameters and returns a solid geometry object.
Input Parameters
- d: Diameter of the snap rivet. Default is 6 mm.
- h: Height of a single unit of the snap rivet, excluding the base and snaps. Default is 10 mm.
- n: Number of units, which multiplies the height. Default is 1.
- F: Push force required to open the solid. Default is 0 N.
- s: Base size of the snap rivet. Default is 1 mm.
- sl: Slot size. Default is 0.3 mm.
Output
- SG: The resulting solid geometry of the snap rivet.
Algorithm Steps
- Retrieve input parameters using the
getfuncparams function, which assigns default values if parameters are not provided.
- Calculate the total height of the snap rivet as
n*h + sl.
- Call the
VLFLsnaprivet function with the calculated height, half the diameter, base size, and other parameters to generate the vertex list (SG.VL) and face list (SG.FL) of the solid geometry.
- Translate the solid geometry using
SGtransP to adjust its position by moving it down by the base size s.
- If no output is requested (
nargout == 0), plot the solid geometry using SGplot and adjust the view and lighting for better visualization.
Example Usage
SGsnaprivet(10, 10, 1): Creates a snap rivet with a diameter of 10 mm, height of 10 mm, and 1 unit.SGsnaprivet(10, 10, 2): Creates a snap rivet with a diameter of 10 mm, height of 20 mm (2 units), and default force.SGsnaprivet(10, 10, 2, 0.5): Creates a snap rivet with a diameter of 10 mm, height of 20 mm, and a push force of 0.5 N.
