UI parity
Last reviewed: 2026-10-10 · Last updated: 2026-10-27 · Change: minor (WIPEOUT closure-aware grips; previously: re-audit of the evidence text against main 41d9b5e95: point entry, tracking, Dynamic Input, grips, scripts, views; percentages not re-measured; previously: distinct polyline midpoint grips) · Target: Autodesk AutoCAD 2027 for Mac (26.0)
How CADCraft's interaction compares with AutoCAD's: point entry, object snaps, tracking, dynamic
input, grips, selection, the command line, chrome and navigation. A drafter's speed in AutoCAD
comes from these, so "the command exists" isn't enough: it has to accept the same input, snap to
the same points and respond to the same keys. Work items: gaps.md.
Headline (estimated): UI/UX fidelity ≈ 48%. The command line, point syntax (FROM, M2P, TK,
point filters, typed snap overrides), the common running snaps, polar/ortho, PolarSnap, object snap
tracking, Dynamic Input (pointer boxes, grip dimensional input, DYNPROMPT), hot-grip options with
several hot grips, shortcut menus and the palettes are real, and so are the Extension, Parallel and
Apparent Intersection snaps (#379). Selection cycling landed (#1143). Missing: lasso selection, grip hover menus,
multifunctional grips on dimensions and text, workspaces and the navigation bar. The 48% and the area
percentages below are from 2026-10-11 and were not re-measured. Remaining: ≈ 110–170 Opus 5.5 hours.
How this was measured
- CADCraft: read from the source on 2026-10-10 (main at
bd2412f): crates/engine/src/{prompt, snap, select, grips, lib, units}.rs, cmd/*, crates/ui-egui/src/*. Not run in this pass.
- AutoCAD: behaviour observed black-box in the running AutoCAD 2027 for Mac
(
plan/autocad/01-observed-ui.md, local only, with reference screenshots that are never
committed), its menu tree (xtask/data/menu-catalog.txt) and Autodesk's documentation.
- Weights (how often a drafter hits each area): point entry 15%, object snaps 15%, tracking and
polar 10%, dynamic input 10%, grips 10%, selection 10%, command line 10%, chrome and palettes
10%, navigation 5%, keyboard and context menus 5%.

yes |
yes (.x … .yz, "(need YZ):"); Z is asked for and dropped (no 3D) |
pointmod.rs |

yes: <a, <<a, <<<a; a typed distance or a pick follows the angle, typed coordinates win |
pointmod.rs |
Object snap overrides (END, MID, INT … NON) |

Tracking, polar, ortho, grid and snap (≈ 70%)

yes, Shift overrides it while held |
yes; holding Shift turns it on or off while held (Session::snap_cursor, snap/tracking.rs) |
| Polar tracking increment |
yes |
yes, measured from ANGBASE; dotted path and "Polar: d < a°" tooltip (snap/tracking.rs, canvas.rs draw_tracking) |
| Additional polar angles, relative to last segment |
yes |
additional angles yes (POLARADDANG); relative to the last segment with POLARMODE bit 4 (snap/tracking.rs, #450) |
| Polar distance snap (PolarSnap) |
yes |
yes: SNAPTYPE 1 steps along the tracking paths by POLARDIST (#450; also over the isometric snap, #633) (snap/tracking.rs polar_snap) |
| Object snap tracking (acquire points, alignment paths, intersections of paths) |
yes, F11 |
yes (#379): resting on a snap point acquires it (+), resting again releases it, seven at most; horizontal/vertical paths, or every polar angle with POLARMODE 2; Shift to acquire with POLARMODE 8; crossings of two paths, a path and an object, and a path and a polar path snap; tooltip names each path; a typed distance (direct distance entry) runs along the path the cursor is on, measured from the point the path comes from. Engine: Session::snap_cursor, snap/tracking.rs; AUTOSNAP bits 8 and 16 |
| Grid (rectangular, major lines, adaptive, limits) |
yes |
rectangular and isometric (30°, 90° and 150° lines), major lines, adaptive display |
| Snap (rectangular, isometric, polar snap) |
yes |

| Isometric drafting (ISODRAFT, isoplanes F5) |
yes |
yes (#556): ISODRAFT and the status-bar toggle set SNAPSTYL and the plane; ISOPLANE / F5 / Ctrl+E cycle Left, Top, Right (SNAPISOPAIR); ortho, direct distance entry and the crosshair follow the plane's axes; ELLIPSE Isocircle (radius or Diameter, also for elliptical arcs); Drafting Settings snap style radio. Engine: snap/iso.rs, cmd/settings/iso.rs |
| Drafting Settings dialog |
yes |
yes (dialogs.rs:36-80) |
| Hatch and Gradient / Hatch Edit dialogs |
yes |
yes (hatchdlg.rs): pattern swatches, gradient colours and shapes, origin, pick points or objects, associative, separate, island detection; Hatch Edit adds boundaries from points or closed objects and removes selected loops; opened by HATCH, GRADIENT (HPDLGMODE), HATCHEDIT, right-click or double-clicking a hatch; no Preview or Inherit Properties |
Dynamic input (≈ 45%)
AutoCAD's heads-up input (F12) has editable pointer-input fields (x, y), dimensional input
fields (length and angle) with Tab between them and lock icons, relative-by-default second
points, dimensional input on grips, a prompt with clickable options and a down-arrow menu.
CADCraft has pointer input boxes since #60 (crates/ui-egui/src/dyninput.rs): value boxes
beside the cursor while a command asks for a point; second and later points default to polar
distance and angle (DYNPIFORMAT = 1 for Cartesian); , and < lock a value and move to the next
box; Tab types the separator; Enter sends a relative entry (DYNPICOORDS = 1 for absolute) and
fills an empty box from the cursor; a plain number stays direct distance entry. Since then: grip
dimensional input (length and angle fields while a grip is stretched, DYNDIVIS, DYNDIGRIP), lock
indicators on locked values, and DYNPROMPT (the prompt beside the cursor, Down Arrow for its
options); distances show in the drawing's UNITS (#867). Missing: DYNDIM (dimension display while
dimensions are edited).

Revision history
| Date |
Change |
Summary |
| 2026-10-27 |
minor |
WIPEOUT grips treat implicit and explicit closure alike; moving the first vertex carries the closing marker, and moving endpoints together keeps both corners editable. Open/closed polyline flags and coincident polyline vertices remain independent (#2256) |
| 2026-10-26 |
minor |
Browser host stores bounded, validated panel layout separately from drawing state; malformed or unsupported records retain defaults. Native workspace storage is unchanged. |
| 2026-10-24 |
minor |
Re-audit against main 41d9b5e95: evidence text for TK and typed snap overrides, PolarSnap, Dynamic Input, hot-grip options, dynamic block grips, SCRIPT, ZOOM Realtime/Dynamic, named views and VPORTS; headline no longer lists selection cycling as missing; the 48% and the area percentages are not re-measured |
| 2026-10-22 |
minor |
Polyline segment midpoint grips use rectangles, distinct from square vertex grips, with matching hover and pick bounds (#1950) |
| 2026-10-13 |
minor |
Filled-region highlight boundaries are traversed in deterministic coordinate order, fixing dash-phase jumps on CPU hover/selection redraws and GPU highlight rebuilds; CPU dash-position, pixel and GPU mesh regressions |

| 2026-10-16 |
minor |
ALIASEDIT opens the Command Aliases dialog (#1381) |
