Release History

• *.*.*:
  • Requests:

  • Bugs:
    • Not all elements are supported. Unsupported elements:
      • assembly
      • quantity
      • expression
      .
    • Exceptional conditions are handled chaoticaly.
    • pi and e constants can only appear in formulas (so one has to write pi / 1.0 instead of pi).
    • All possible elements childrens are not always checked.
    • Angle ranges are not checked.
    • Defaults for positions and rotations are not obtrained from Schema.
    • Defines from Solid may be missed.
    • Units are not tested.

  • Bug fixes:
    • Units handled correctly.
    • Repeated names (of references) are made unique so that all solids are show.
    • Sphere.theta is in (0, pi).
