Drilling into a child deactivated its parent and evaluated the parent at
its final step. After navigating to an earlier step, this moved surrounding
geometry and separated the child's editing transform from its placement.
Keep the complete editing path active at its chosen steps, and use that
path when filtering ancestor geometry for rendering. Rebuild the transform
from the selected instances when restoring a tab so changes in an ancestor's
own tab also keep the editing target aligned. Returning through a breadcrumb
deactivates only departed descendants; ending editing restores completed
assembly poses while retaining stored step choices.
Also route Submodel Properties to the model currently being edited rather
than the tab model.
Validated the macOS Qt 6 application build, all 8 Qt Test cases, and 106
focused compiled-application checks covering ancestor poses and visibility,
properties edits, tab switching, breadcrumbs, focus status, and exports.
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.
Keyboard edits during dragging started a new history sequence and discarded the drag's original undo state. Deleting the dragged piece also left tracking active with a dangling piece pointer, causing the next mouse move to crash.
Accept the active drag before dispatching every command except Cancel, which retains its existing cancellation behavior. Keyboard edits and deletion then run as separate undoable operations after tracking has ended.
Validation: macOS application build and Qt Test suite passed. An offscreen harness using the production view, model, and command handlers reproduced the Delete crash and lost drag undo state before the fix. The fixed version passed five runs each of Delete with continued mouse movement, keyboard movement with undo, and Cancel.

Replace manual piece-data retain/release bookkeeping with shared copyable
asset-reference handles. Pieces, models, selection, minifigs, thumbnails,
and stored insertion previews retain their dependencies explicitly, while
transient queries continue to borrow pointers.
Separate registered lookup and acquisition from asynchronous load requests
and explicit readiness waits. Keep loader-held references through work and
notification delivery, resetting shared request handles on the UI thread
and guarding callback-triggered library teardown.
Validated with the Qt 6.10 debug build and 26 offscreen lifecycle checks,
including cancellation, stale requests, copy/move operations, model/preview
teardown, undo, project merge/export, and loader shutdown.
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.
Render selected pieces with an outline above scene geometry and a faint selection-colored fill only over obscured portions. Preserve line-only selection colors and insertion preview tint, and suppress bounding box corners in outline mode.
Keep the existing tint and edges mode as a preference and fallback when outline rendering is unavailable. Own outline framebuffers in each view, keep OpenGL operations in lcContext, and capture selection visibility before the grid through a callback scoped to each scene draw.
Validation: debug build and desktop OpenGL checks passed for occlusion, transparency, MSAA, HiDPI, line-only selection, framebuffer fallback, grid exclusion, and widget resource cleanup.
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.
Report missing generated meshes and failed image writes, keep thumbnails and interactive geometry using their fallback behavior, and frame command-line images at the requested step or full range. Use explicit mesh loader flags and reject incomplete synthesized meshes. Keep selection and ray tests aligned with the rendered mesh.
- Draw a shared cube for parts whose meshes or textures are still loading.
- Update model bounds, picking, views, and loading status as assets complete.
- Wait for required assets before thumbnails, screenshots, instructions,
and geometry exports; report failures instead of rendering placeholders.
- Render and pick direct geometry in external projects.
- Defer shared buffer repacking until pending loads finish.
Add a camera-facing rotation ring with hover feedback, and replace free XYZ rotation with a trackball interaction. Improve rotation-disc feedback, cursor behavior, snapping, and submodel transform handling.
