Many industries are starting to go paperless, so I'd like to see Rhino 5 fully support Model Based Annotations (dimensions, tolerances, GD&T, leaders, and notes) that are recently available in STEP AP214 and AP203 Edition 2. These preclude the need for 2D drawing sheet layouts.
Rhino can already create annotations in 3D, so this seems like a natural extension to be able to read and write them in an industry standard format.
ASME Y14.41 is probably the best standard for how these Annotations can be presented in 3D.
I have been looking into MBD in Rhino as well, and would like to see better support.
Out of curiosity is there anything that Rhino can't do PMI/annotation wise in the model? It's more about when exported out to a step file, 3D pdf, or even iRhino3d that this information comes along. Correct?
Dennis, other than inability to capture annotations to/from STEP files, the other big thing missing in Rhino is GD&T. To make MBD work, Rhino will need Datum Identifier entities and GDT symbol block entities.
As an aside, I don't know any of my associates who use the existing Rhino 2D drafting tools because linear dimensioning is just too ineffective compared to ASME Y14.5 GD&T. On the bright side, I think these would be fairly easy things for the Rhino developers to incorporate in the 3D environment. Trying to compete with SW or Inv in the 2D annotation world is IMO not worth the effort, but this is Rhino's chance to leap ahead of those other CAD packages.
