- Implement Apollonius PPC (Point-Point-Curve) and multi-tangent CCP solvers for lines in arc.rs
- Support tangent line snapping for all 3-input arc combinations (Tangent-Point-Point, Point-Tangent-Point, Tangent-Tangent-Point, Tangent-Point-Tangent, Point-Tangent-Tangent)
- Resolve TangentGeom::Line f32 truncation in snap.rs to preserve true f64 key vertices during tangent evaluation and TangentObject construction
- Preserve strict CUT_TOLERANCE (1e-7) in trim.rs while ensuring tangent contact points are detected accurately
- Add unit tests for line tangency solvers, tangent trim detection, and angular precision sweeps
Allow users to temporarily override object snaps during active point prompts by typing at least the first 3 letters of any snap mode (e.g. MID, END, CEN, PER, NON). The override activates for the next point pick only and automatically restores running snaps once consumed or cancelled.
- Add transform_ellipse_geometry helper in scene::view::transform to compute exact principal semi-axes, normal, ratio, and shifted arc parameters under any affine transform (negative scales, reflections, negative rotations, non-uniform scaling, and translations).
- Use transform_ellipse_geometry in block_cache::transform_tangent for TangentGeom::PlanarEllipse so GPU analytical instances and curve endpoints match true WCS positions.
- Update entities::ellipse::apply_transform to use transform_ellipse_geometry for complete scaling, rotation, mirroring, and affine transformations.
- Clean up tangent parameters in to_render for Ellipse so start_param and end_param are consistently unwrapped.
- Add comprehensive unit tests in transform.rs, block_cache.rs, and ellipse.rs verifying negative rotations, negative scales, and distant origins.
When a plugin command was dispatched, record_recent was called but
tabs[i].last_cmd was never set. Consequently, pressing Enter or Space on
an empty command line after running a plugin command failed to repeat it.
This records tabs[i].last_cmd on plugin dispatch and requests command-line
focus and dynamic input syncing when an interactive plugin command starts.
- Add LayerConfig struct and add_layer / modify_layer methods to HostApi trait
- Implement IPC request/response serialization for AddLayer and ModifyLayer
- Implement HostSession methods with CAD property defaults and selective modification
- Refresh layer panel UI and invalidate scene layer dependencies upon layer changes
- Add unit tests for add_layer with defaults and partial modify_layer
