In-place editing could use the tab model's step and focus, lose its active
state after switching tabs, or resolve a nested instance through the wrong
parent. Entering before the final animation key also moved geometry when
drilling into a child.
Use the edited model for step controls, step edits, visibility, and focus
coordinates. Restore that editing target when returning to its tab, include
animation keys and finite hide steps in the last step, and retain the
selected instance path and transforms during nested editing.
Show the editing path only during in-place edits, with links to ancestors
and a close control to return to the tab model. Stack Find/Replace beneath
it and preserve full names in accessible text and tooltips. Add translated
source entries without changing existing translations.
Add a regression test for final-key tracking through time and key edits.
Validated with the macOS Qt 6 application build, all 8 Qt Test cases, and
51 focused checks against the compiled application for steps, tab switching,
focus status, breadcrumbs, and Find/Replace layout. Visually checked the
viewport overlay and its placement during nested editing.
Full before-and-after model snapshots accumulate large amounts of memory during editing, even when an operation changes only one object. Compact completed edits to retain only added, removed, or modified object states, with ordering metadata kept only for structural changes.
Restore objects by stable IDs, including group relationships, and detach views before removing cameras. Compose merged edits from their deltas and compare animation keys as well as current property values so keyframe-only edits remain undoable.
Use PieceData consistently for the shared part/model record, its related
APIs and variables, and its source files. Keep the existing reference
counting and loading behavior so ownership and readiness changes can be
reviewed separately.
Large models can extend beyond the default far plane after fitting,
leaving the view blank or clipped. Pass an explicit adjustment flag
through view, model, and camera fitting, and reuse the fitted bounds
to expand clipping with a margin, rounded up to multiples of 10,000.
Adjust restored ordinary cameras after applying their saved state.
Preserve named cameras and explicit command-line clipping planes,
and avoid recalculating clipping during redraws or navigation.
Route output fitting through the view and move the bounds policy
definition out of the precompiled header.
