Mitcad 0.28.0: print settings and materials, placement by picked geometry, Gear Pair and Belt Drive, measurements you keep, and formulas

• Print settings and materials: a material carries its density, its
  appearance and its filament; printers and processes are set in 3D
  Print, with the settings in categories and a library of base, user and
  project items. Settings are read from and written to the 3MF projects
  of Bambu Studio, OrcaSlicer, QIDI Studio, PrusaSlicer and Cura, so
  that the slicer opens each body with its printer, process and
  filament.
• Placement by picked geometry: primitives, holes, coils, bearings,
  gears and pulleys are placed by the faces, edges and points you pick,
  with value boxes on the handles.
• Gear Pair and Belt Drive: choose a pair of gears or a belt drive by
  ratio and centre distance, with undercut and belt checks.
• Measure: measurements in the design's coordinates and between axes,
  a history of measurements, and measurements kept in the design,
  shown as dimensions and saved with it.
• Parameters: spreadsheet-style functions and syntax, text parameters,
  limits (minimum, maximum and step) on any parameter, CSV export and
  import, and a formula builder that shows each function's signature.
• Move/Copy: points and axes on other components, and on either copy of
  a component placed twice, so a component can be moved onto another
  one's point.
• Create Sketch: new sketches open with the design's Z up, and the
  hidden origin planes are offered in the browser's Origin folder.
• Extrude: Two Sides refuses a negative distance and points to Start:
  Offset for a solid on one side of the sketch.
• Thread: a face selected before the command suggests the size and the
  class.
• Preferences: custom mouse navigation with its own bindings and camera
  speeds; the dialog fits the screen.
• Timeline: features are readable and shown through solids, with
  tooltips.
• Connect AI Assistant: sets up a local AI assistant to work with the
  open design.
• Faster: sketch drags and edits of large sketches, region finding,
  feature previews that no longer block the window, and .f3d import.
• Fixes:
  • Finish Sketch stays in the ribbon in narrow windows.
  • The selection card shows the Move Face and joint cards again.
  • Names in menus and dialogs follow one set of terms.
• macOS: dialogs use the platform's controls and conventions.
