I was able to get the norms and could update the definitions accordingly.
For example in the ISO 10462, sizes smaller than M3 are not defined and your definition files should only contain what is really defined.
- add definitions for IS 2009, 7046 and 12474
- remove useless file for a ISO 14583 since there are no such screws on the market
- rename "coarse" to "regular" since this what it actually is according to the norms
- uniform the x1 threads (for x2.0 etc we use a trailing zero and for some we use x1, for some already x1.0, thus consistently use x1.0)
- add some ISO 10642 entries
- correct ISO 4762:
- correct some values
- the does does not define a size M27
- add the two missing sizes
- propose valid values for the cut depth and diameter when creating new holes
- add new definitions for metric fine
- some code simplification and comments
‣ Make countersink and counterbore on metric holes freely definable by user.
‣ Fixed the Naming of M1.6, M2, M2.5 and M3.5
‣ Added constructor for custom enums from Enums to PropertyEnumeration
‣ Put definitions of cut-types (counterbore/countersink) for
screwtypes into json-files for easy modification.
‣ Allow users to put its own definitions in json-files in
[UserDir]/Mod/PartDesign/Resources/Hole
‣ Contains several examples of cut-type definition json-files that are
propably not production-ready.
This uses a local copy of nlohmann::json¹ to read json-files.
