Things that just came up
There is a proposal to drop spherical coordinate from Part 42 Edition 2
- This was not in edition 1 (1994)
- The SAME entity is in Part 104
- This means that spherical_coordinate will not be added to Part 42 E2
There is a proposal to restrict the combinations in Part 42 of loop and path to only allow the complex instance of edge_loop and path
- Vendors are concerned about vertex_loop and poly_loop
- There may be valid cases of vertex_loop and path in BREPS
- poly_loop and path is used in faceted BREP
There is also a proposal to expand restrictions to limit other entity combinations
- Need concrete list of what will be allowed or disallowed
- Very dangerous in the general case
Current proposal- do #1 sit on #2 and #3
