DIMLINEAR / DIMALIGNED / DIMRADIUS / DIMDIAMETER / DIMANGULAR created on a
sheet now report the model measurement of the geometry seen through a
viewport, at any viewport scale, while definition points, the dimension line
and the text stay in paper coordinates and the annotation keeps its sheet
size (DIMSCALE is untouched).
A viewport frame is a similarity - uniform scale plus in-plane twist - so
projecting the model span onto the paper axis and compensating gives exactly
the raw paper measurement times 1/scale. No geometry is rewritten: the
compensation is persisted once as a negative DIMLFAC override on the
dimension and applied once by the linear formatter, so preview text,
dimension text, the properties measurement row and DXF/DWG export all agree.
User measurement multipliers fold into the same magnitude, and an explicit
text override still bypasses formatting entirely, so it is never re-scaled.
Angular dimensions are never compensated - a similarity preserves angles.
Mixed input (one point through viewport A, another through viewport B or on
the sheet) is refused rather than silently mis-measured: the command line
explains why and the dimension falls back to plain paper measurement.
A dimension measured through a viewport is left unassociated: its definition
points are projected paper coordinates, so inferring a paper-space
association would bind it to geometry that is not there. PR3 records the real
dimension -> viewport -> entity chain.
The result is one ordinary dimension entity carrying one style override, so
undo/redo works through the existing history with no new out-of-document
state.

Add MTP (Midpoint Between Two Points) as a keyword that can be typed
during any point-picking command (e.g. LINE) to suspend the current
command, prompt for two points, and return the midpoint to the parent.
- New Mid2PointCommand registered under both "MTP" and "M2P" aliases
- ReturnPoint CmdResult variant feeds the resolved midpoint back to
the suspended parent command
- MTP/M2P typed during a point step suspends the active command and
starts the midpoint modifier; Escape restores the parent command
- Preview wires show a rubber-band line with a triangle marker at
the midpoint
- Character-by-character typing is routed correctly even with dynamic
input active (digits no longer leak into dyn fields)
- Three automation tests cover the full workflow, ESC restoration, and
dynamic-input character routing
None of the 17 constraint commands (HCONSTRAINT, VCONSTRAINT,
PCONSTRAINT, QCONSTRAINT, ECONSTRAINT, TCONSTRAINT, NCONSTRAINT,
NRCONSTRAINT, LCONSTRAINT, FXCONSTRAINT, SYCONSTRAINT, CCONSTRAINT,
EDCONSTRAINT, CPCONSTRAINT, MPCONSTRAINT, OCCONSTRAINT, DCONSTRAINT,
ACONSTRAINT) carried an inventory::submit! registration, so they were
invisible to command-line autocomplete, the MCP commands listing, and
the ALIASEDIT shortcut editor (which rejects a custom shortcut target
that isn't in this same registry). Each constraint module now
registers itself, with a regression test pinning the full set.

Brings in 54 commits from origin/main: a selection-performance overhaul,
surface thickening, GPU-native wide/tapered stroke rendering, continued
ocs_doc_api evolution, and assorted fixes/polish (block double-click
editing, DWG hatch/database repair, clipboard, collapsible Properties
sections).
Six real conflicts, all where this branch had independently re-applied
a fix upstream later revised or already carried natively:
- src/app/automation.rs, src/app/command_driver.rs: combined both
sides — kept this branch's sketch-constraint/named-parameter loading
on "new"/"open", adopted main's Scene::clear()/material_base_dir and
its newer rebuild_derived_caches() over the older bump_geometry().
Scene::clear() (src/scene/entity.rs) now also resets
sketch_constraints/named_parameters, so every caller gets this for
free instead of each call site repeating it.
- src/io/mod.rs, src/scene/render_graph.rs: adopted main's design
outright (commit 973af87d, authored by Hakan directly) — a large
MINSERT is no longer purged as "corrupt" at load, only its rendering
is bounded, preserving the source data. This branch's own earlier
design (reject at load) predates that revision.
- src/scene/pipeline/mesh_gpu.rs: adopted main's valid_rgba_size()
guard (a real robustness improvement over this branch's version).
- src/snap.rs: replaced wholesale with main's version — this branch's
copy was an explicit verbatim snapshot from an earlier upstream PR
(commit 4c264b8c) with zero constraint-system-specific content, and
main has since evolved it considerably further.
Also removed two now-dead duplicates the merge surfaced without a
conflict marker (both branches had independently fixed the same
things): the OPTIONS/OP command dispatch/autocomplete entries, and
automation.rs's open_finalizes_and_purges_like_the_ui_open_path test
(kept main's version, which covers strictly more: solid_models/
material_base_dir reset on "new").
Full workspace suite passes (812 lib tests + this branch's own 24
constraint/persistence integration tests) except the one pre-existing,
unrelated font-test failure already present on main. Zero clippy
findings in the hand-written merge resolution itself; the ~1,171
warnings clippy reports are pre-existing in the 54 absorbed commits,
not introduced here.

New ConstraintKind variants — Concentric, CenterPoint, Colinear, Midpoint,
Fixed, PointOnCurve, EqualDistance, Symmetric — each built entirely from
existing ocs_gcs (FreeCAD planegcs) primitives, no new solver math needed.
build_constraint now returns Vec<Rc<dyn Constraint>> instead of
Option<Rc<...>>, generalizing the old Coincident-only "needs a second
system-level constraint" special case to every kind that needs one.
Wired into the ribbon (7 new buttons), a new point+pre-selected-entity
command for CenterPoint/Midpoint/PointOnCurve, a new 4-point command for
EqualDistance, and the existing DWG-native class-name mapping (all 8 reuse
the same generic "plain Geometrical node" path already built for
Coincident/Horizontal/etc.). Deliberately not modeled: Normal and
EqualCurvature, which for this app's Line/Circle-only entity model would
just be Perpendicular and Equal wearing different DWG class names.
Also makes DWG-native constraint persistence opt-in (Options > General,
off by default) rather than unconditional: a scope that doesn't yet have
the native graph is only given one when the setting is on, but a scope
that already has one — from an earlier save, or a file that came from
real AutoCAD — keeps getting it resynced regardless of the setting, so
toggling it off never freezes a stale graph in place.

Named parameters (docs/named_parameters_design.md, stages 3-4):
- ParameterTable (src/scene/named_parameters.rs): a document-wide table of
named formulas, each resolved through a shared expression evaluator with
cross-parameter references, cycle detection, and division-by-zero/parse
error reporting. SketchConstraint::driving_param becomes DrivingValue
(Literal | Named) instead of a bare f64, resolved at solve time by
sketch_solve::build_constraint via Scene::named_parameters.
- Persistence (src/scene/named_parameters_persist.rs): same lazy XRecord
model sketch_persist.rs already established, synced around open/save.
Bumps the sketch-constraint XRecord's own format version (1 -> 2) since
DrivingValue's shape doesn't line up with a version-1 blob's bytes.
- PARAMETERS command and its editor (src/ui/window/named_parameters.rs):
add/remove/edit rows, live validation, duplicate-name detection: Apply
defines the table and re-solves every constraint scope with a
named-parameter-driven constraint (command_driver.rs). Distance/Angle
constraint prompts (modules/draw/constrain/value.rs) now accept either a
literal or an existing parameter's name, mirroring how the constraint's
own value prompt already worked.
- Undo scope-down carried over from this project's own established pattern
(constraint-system stage 9): the geometry an Apply moves is one undo
step, but the parameter table edit itself has no undo entry yet — a
documented follow-up, not a silent gap.
UI scale setting (src/app/settings.rs, app/mod.rs, ui/window/options.rs):
a whole-interface scale percentage (50-200%), wired directly into iced's
own per-window scale_factor hook rather than per-panel font-size
plumbing, so it applies immediately to every panel, dialog, and the
ribbon at once. Persisted alongside the existing lineweight-display-scale
setting.
OPTIONS/OP command dispatch (app/commands/view.rs, app/commands/mod.rs):
OPTIONS was registered for autocomplete but had no dispatch arm — the
Start-tab welcome screen's own button was the only way to reach it.
Found live-testing the UI-scale setting, unrelated to that feature
itself. "OP" is AutoCAD's own short alias.
help/: a new self-contained static user-help manual (manual.md as the
authored source, tools/build_help.py splits it into the committed static
HTML pages plus search index) — not yet wired into the application.
64 new/updated tests across the named-parameters and constraint-prompt
changes.

Ports FreeCAD's planegcs 2D geometric constraint solver to Rust as a new
crates/ocs_gcs workspace member, and wires it into the document/scene model
as a persistent SketchConstraintSet: Coincident, Horizontal/Vertical,
Parallel/Perpendicular, Equal, Tangent, Distance, Angle and Radius
constraints that re-solve live (including mid-drag, not just on release),
render glyphs and a DOF badge, flag conflicts with a one-click resolver
pill, and round-trip through save/load via an XRecord blob.
Also includes docs/command_reference.md (a statically generated reference
of every registered command and its prompt sequence) and
docs/named_parameters_design.md + docs/backlog.md, which hand off the next
queued feature (a named-parameter/expression table) and consolidate every
deliberate scope-down and open gap found along the way, so a fresh session
has a complete starting point.
