- rotation turns the whole sheet of views about `at` as one rigid body: the
prims, the recorded WCS `bbox` (plus the sheet-frame `frame_bbox` the next
view is laid out against), the detail marker, and every dimension intent
(points, text position, and the linear measuring direction + rotation).
Measured headless: rotation=90 at (100,100) now draws (70,100)-(100,172),
records exactly that box, and leaves only the 2 diameter chord defpoints
off-geometry (was 4, up to 47.5 mm away).
- dimension_part dimensions only views whose record is not `dimensioned`,
takes `views=[indices]`, refuses a view already dimensioned by name
(ISO 129-1), writes the flag back, places the hole table once, and refuses
a fit no target view claims before drawing anything. A view the dimension
layer emits nothing for (a detail) is reported in `skipped` and left
unflagged. mech_dimension_part gains the `views` argument.
- draw_prims checks hatch_add_boundary's {"ok": False}: the hatch is removed
and the failure raised, never left solid through the bore. An engine whose
capability map says `hatch_edge_paths` is unsupported (the live one) is
refused before any prim of the view is drawn.
- a view scale other than 1.0 is refused by name in draw_part and add_view
(views are drawn full size; the scale would only have been recorded).
- add_view's collision step compares real rectangles on both axes and steps
along the projection axis layout_origin chose, so a third-angle view is
never shoved back onto the front view and a top view keeps its alignment.
- draw_from_spec validates `at` / `rotation` into the `parts[i]:` path and a
transaction that cannot open is a ValueError (a ToolError at the tool).
No new ActiveX member is called: the change composes existing contract
members (dimension_linear rotation, entity_delete, capabilities()).
