Hole dialog discussion

[ToniTen]

Are the names for the Hole Cut translatable? Counterbore and countersink don't mean much in languages other than English. If they are translatable, I propose the following translations for Spanish (Spain):

counterbore = refrentado
countersink = avellanado

These translations are done via Crowdin.

These translations are done via Crowdin.

These names are read on runtime from files. I don’t know enough about the freecad Enumeration classes, that are used here, to give a based opinion, but I doubt translation is possible here without major changes in the code.

With git commit b7d763a1c they can be translated now.

Might be fun to see how "Cheesehead" is translated into various languages.

The hole dialog is a beast - so many possible combinations when changing settings.

While testing I found several issues according to the countersink angle.

This PR fixes them: https://github.com/FreeCAD/FreeCAD/pull/4050

I had a look at the norms, and they only define screw heads, not how the holes for a countersink/bore must look. So you are not only free to cut with a larger or smaller diameter but also with a custom sink angle.

when changing the depth for a countersink, nothing happens.

This is fixed as well with this PR.

--------------------

Today I realized that the hole feature does not provide cuts for screws according to the norm ISO 8677. So the dialog should in future support also square cuts.

Please have a look at "DIN 74 countersinks for countersunk head screws" and including DIN ISO 20273.

The problem is, these cost a fortune: DIN 74 (42,88 €) and DIN EN 20273 (30,23 €)
That’s why most developers here do not have access.

This defines hole diameter sizes:

or
http://www.iim.maschinenbau.tu-darmstad ... 20273.html

So we have 2 issues:
- some of our "close fit" diameters for metric holes are incorrect (we use e.g. values like 3.15 despite the norms define a precision of max 0.1 mm)
- we don't support the defined "coarse fit"

I'll correct/add this after the pending PR is merged.

I asked Yorik if this can be payed from the FreeCAD account.
