The draft says this:
I think this is just fine. If we want stronger wording, the last line can change to this:
Quote:Numbers in files shall not exceed five decimal places
Four decimal places (at a minimum) shall be used in high-res primitives and any other file that is designed to be scaled (for example, cylinder sections, boxes, rectangles, discs, edges, etc.)
This allows such primitives to be scaled by a factor of ten while still preserving three decimal places of accuracy. The primitives reference indicates which primitive families are not designed to be scaled.
For all other files, three decimal places are sufficient. Any file exceeding this recommendation (except in cases to match primitive vertexes) should have a justification by the author.
I think this is just fine. If we want stronger wording, the last line can change to this:
Quote:For all other files, three decimal places shall not be exceeded with the exception of matching primitive vertexes or on a case-by-case basis with justification by the author.
