Changelog

Version 0.7.0

Minor version increment. Hex nuts & bolts spawn rotated by 30 degrees.

New Features:

  • Square Nuts and Bolts! plus any number of sides 3 to 16. #18
  • Robertson (square) bit option. N side bit option with any number of sides 3 to 16. Both include toggle box for security pin. #60
  • 5 new bit options; Star, Double Square, Double Hex, Triple Square XZN, 12-Spline. #60

Fixes:

  • Bolts can now maintain a manifold junction between the head and shank for non 36 Div Count. Depending on the selection of Head type and Bit type the Div Count parameter can be altered. For example an 8 side head with a hex insert is manifold when Div Count is set to a multiple of 24. #4
  • Bolt (Hex) heads and Nuts have bevel set to 30 degrees rather than 45. #18
  • Source code clean up and variable renaming. #51
  • Fix inability to add bolt in edit mode. #62

Changelog

Version 0.6.0

New Features:

  • Users can now select multiple bolts and apply changes to all at once. #38
  • The UI now displays how many bolts will be affected by the "Change Bolt", improving clarity. #38
  • Added presets for coarse threads. #40
  • Added a new threaded root type property with its value and made it visible in the UI so users can change it (Flat and triangle for now!). #40

Fixes:

  • 5-pole at corner of Hex nut and bolt removed, by removing redundant edge loop. #43
  • Hex nut and bolt height clamped so to remain manifold objects. #43
  • Internal thread no longer has a rank and is no longer limited to integer revolution length. #9
  • The menu for Change Bolt no longer shows if no active object (bolt) is selected which fixes duplicate bolt generation. #38
  • Set the pitch maximum value as soft_max = 7. #40

Not shipped, but included in the tag, is a new "tests" folder containing some basic regression tools. #36

Changelog

Fixes:

  • Pan head now accepts larger bits in a manifold way & has radius to shank. #25
  • Added 12 Point Head and Nut to the BoltFactory parameters list so 'change bolt' works correctly. #23
  • RemoveDoubles called twice to make a better effort of pruning duplicate vertices. #2
  • RemoveDoubles enhanced to now remove duplicate faces.
  • Lock nut was non-manifold, visible geometry broadly unchanged, interior faces removed.
  • Internal_Thread_End_Verts fixed to remove random_offset which was attempting to avoid mesh error.
  • In Create_Thread_End_Verts fixed non-manifold tip thread for very fine or coarse pitch bolts.
  • Corrected size of T55 and increased number of Torx bits in the GUI dropdown as per ISO 10664:1999(E). #21
  • Significant increase in code documentation.
  • 12_Point bolt head with an insert bit was non-manifold, visible geometry unchanged. #4
  • 12_point nuts had intersecting faces, default dimensions changed in presets. #4

Known Issues:

  • After loading a default Some bits are too large for the head of a 12 Point bolt.
