ScrewsMetric

It appears that you have a comprehensive documentation for a set of OpenSCAD modules related to screws, bolts, nuts, and washers in both metric and imperial systems. The documentation covers various aspects, including: 1. Bolt and nut selector systems: `ScrewsMetric-core-BoltSelector.scad` and `ScrewsMetric-core-NutSelector.scad` 2. Washer database and access functions: `ScrewsMetric-core-Washers.scad` 3. Interface modules for the core modules: `ScrewsMetric-BoltSelector.scad`, `ScrewsMetric-NutSelector.scad`, `ScrewsMetric-Washers.scad`, `ScrewsMetric-Base.scad`, and `ScrewsMetric-Modules.scad` 4. Optional modules that avoid addressing the structure in any way: these modules use indexing to access values and can be used with or without loading the core modules. 5. Using indexes instead of names for values is not recommended, as it can lead to nonsensical results if numerical operations are performed on the indexes. 6. The underlying array `M` has a structure that may change in future versions, so using it directly is discouraged. 7. A function `isValueInScrewsDatabase(a, b)` is provided to check whether a value exists in the database without risking errors if the value does not exist. Some key points to note: * The modules use indexing to access values, and using numerical operations on indexes can lead to nonsensical results. * The underlying array `M` has a structure that may change in future versions. * Using the `isValueInScrewsDatabase(a, b)` function is recommended for checking whether a value exists in the database. Overall, this documentation provides a comprehensive overview of the OpenSCAD modules related to screws, bolts, nuts, and washers. It highlights important considerations for using these modules effectively and avoiding potential pitfalls.
