- there is the ISO 273 describing clearance holes, so we need to take these values. Only if we have a size not defined in the norm, we calculate
- add the coarse (wide) type for clearance holes from ISO 273
- add all screw thread sizes defined in DIN 13/ISO 261
- rearrange thread dialog to make it more compact
- change name "fit" to "clearance" as discussed
- add tooltips to the dialog
- fix issue with TaperedAngle dialog field
- change a size name because the norms define "M1" not "M1.0"
- there is no reason to hide it and even a bit tiring to open it manually since most no new primitives should be at the origin
- give the combobox to select the primitive type a reasonable name, this helps to understand the code better
- fix bug that custom angles were overwritten
- the norms only define screw heads, not the cut for them, so also a custom angle is possible to sink a metric screw
- use better step in UI since one changes the presets only in fractions of a millimeter (otherwise it would be a different hole size)
- handle case of no cut
- calculate change in diameter when adding depth to countersinks
Fix MillFace div by zero error reported in forum at https://forum.freecadweb.org/viewtopic.php?f=15&t=51415.
Rotational-related variables were exposed to non-rotational code block. They have been moved into correct rotational code block.
Relocate the rotational analysis code into smaller independent methods to allow for easier maintenance and support.
Commented out recently added debug object creation statement.
The `isFaceUp()` method in the PathAreaOp module was returning false results in some instances.
Rotational code has been consolidated and better organized to fix certain errors reported in the forum.
Overall, this code section has been better organized as a part of the necessary fixes.
- propose cut values also for UTS profiles
- the UTS defines coarse and fine while for ISO it is regular and fine, thus fix the name
- for the dialog: set minimum values to zero (angles etc. cannot be negative)
- 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
