Record ownership transfers in the timeline so earlier Join/Cut membership, world placement, machining data and styles survive component moves, edits, independent copying, undo and reopening. Preserve pending positions in history snapshots and keep constructor transfers ordered during feature redefinition. Retain shallow sheet pockets and exact planar intersection islands through unfold/refold, with depth-aware flat previews and DXF export. Store explicit 3D wire coordinate spaces and migrate known legacy provenance without moving saved points or analytic fits. Infer unique eligible cylindrical Emboss targets, align Revolve manipulators with actual extent geometry, and discard obsolete preview errors after input correction. Certify constructed and immutable imported face styles using exact source metadata while preserving legacy face names. Upgrade designs to format10 with bounded validation and geometry-preserving legacy migration.

Opening a STEP or IGES file creates a design with the file's bodies as a base feature, and inserting one adds them to the current design. Later features build on them. Mesh bodies render, measure, move and export, but solid features need B-rep bodies.
Saves are atomic: a crash at any moment leaves either the old file or the new one, and the
replaced version is kept as <file>.bak. Unsaved changes are autosaved to a recovery folder,
and the next launch offers to recover them. Older design files are upgraded on open, and files
from a newer version are refused with a message.
Current designs use format 10 for recorded body transfers, explicit 3D curve coordinate spaces and certified face bindings, alongside semantic configuration styles, associative free-form offsets and cylindrical emboss selections. Older ownership maps, geometry and expressions retain their saved meaning. Legacy 3D curves with retained associations receive their producer's coordinate-space marker without changing any saved points; detached curves retain world coordinates. A lost cross-component association refreshed by an older build may need an explicit relink or refresh when its source returns. Loading never guesses a numerical correction. Association records, coordinate arrays and placements are bounded and checked.
