Roadmap

From the Musa CAD repository

This page shows docs/ROADMAP.md as it is in Musa CAD 0.8.0. The developers keep it next to the code; to change it, edit it there.

A survey of what is not yet implemented, grouped by theme, with the AutoCAD behaviour each item is measured against. docs/COMMANDS.md is the per-command status table and docs/TODO.md holds the fine-grained deferrals with rationale; this file is the map above both, and each group below corresponds to a GitHub issue.

Status legend: P0 blocks ordinary drafting · P1 expected by a professional user · P2 completeness / parity.

A. Dimension editing parity — #20, #21, #28

The dimension model is strong (value computed from def points, never baked, one shared compute_dim_geometry). What is missing is the editing surface AutoCAD gives.

Item	AutoCAD behaviour	Priority
Text override	Done (#20) — <> expands to the measurement.	✅
Text reposition grip	Done (#21) — text grip on all five types, connector leader, “home text”.	✅
DIMBASELINE / DIMCONTINUE	Done (#28) — DBA / DCO chain from the last dimension’s extension line.	✅
DIMJOGGED / DIMARC / DIMORDINATE	Done (#28) — DJO / DAR / DOR, native and DXF.	✅
Narrow-dimension fit for radial/angular	The ISO 129-1 fallback covers linear/aligned only.	P2
Short-leader variant for outside text	ISO 129-1 permits the value on a short leader.	P2

B. Tables and structured annotation — #22, #29

Item	AutoCAD behaviour	Priority
TABLE entity + TABLESTYLE	Done (#22) — merged cells, per-cell alignment, style-driven text heights. Cell editing staged.	✅
Text STYLE table	Done (#29) — STYLE / -STYLE, a current style, PR style picker, native + DXF STYLE table.	✅
FIELD	Date, time, filename, login Done (#33), refreshed on regen. Still open: sheet number and object-property fields.	P2

C. Missing draw primitives — #23, #33

The store already has arenas for splines and points; the commands are missing.

Item	Priority
SPLINE, ELLIPSE, POLYGON, POINT, XLINE / RAY commands	Done (#23) ✅
DONUT, REVCLOUD, WIPEOUT	Done (#23, #33) ✅
RECTANGLE first-corner options (Chamfer / Fillet / Width)	Done (#23) ✅
HATCH gradient fills	Done (#33) — two colours along an angle, DXF gradient block both ways. ✅

D. Missing modify commands — #24, #27

Item	Priority
STRETCH	Done (#24)
BREAK, LENGTHEN, ALIGN	Done (#27) ✅
DIVIDE / MEASURE	Done (#27) — points at intervals; the Block option is still open. ✅
PEDIT	Done (#27) — Close/Open, Join, Edit vertex (Insert/Delete/Move), Spline, Decurve, Reverse, Undo. ✅
TRIM / EXTEND / FILLET on curve entities	Done (#27) ✅

E. Block authoring — #25

Blocks can be imported and placed; they cannot be created in-app.

Item	Priority
BLOCK / WBLOCK — define a block from a selection	Done (#25) ✅
EXPLODE — instance → geometry	Done (#25) ✅
REFEDIT — edit a definition in place	Done (#25) — REFEDIT / REFSET / REFCLOSE. ✅
ATTDEF / ATTRIB — block attribute text	Done (#25) — ATTDEF, INSERT prompts, ATTDISP, ATTEDIT, DXF ATTRIB. ✅
XREF — external references	Done (#25) — attach, detach, reload, re-read on open. ✅
EATTEDIT / BATTMAN — attribute dialogs	Done (#25) — the Enhanced Attribute Editor (also on double-click) and the Block Attribute Manager with sync by tag. ✅
Multi-line attributes; a Block Editor mode of its own (BEDIT)	REFEDIT edits in place today.

F. Raster images — #10 (remainder)

Done: model, decoder seam, persistence, plot, viewport display (a textured-quad pipeline with a per-definition texture cache), IMAGEATTACH / IMAGECLIP (rectangular and polygonal) / IMAGEFRAME, the 8 MB embed limit, and DXF IMAGE/IMAGEDEF both ways (the writer now gives every record a handle and carries CLASSES and the image dictionary).

G. Paper space, layouts and views — #26, #33

Item	Priority
Layouts / paper space + viewports	Done (#26) — layouts, paper-space entities, tabs, sheet plot, MVIEW viewports, MSPACE / PSPACE through a viewport. ✅
Named views (VIEW), REGEN, VPORTS	Done (#33) — VPORTS: tiled model-space viewports with named configurations. ✅
Per-viewport layer freezing (VPLAYER)	Done (#26) — Freeze / Thaw / Reset / Newfrz / Vpvisdflt, the layer manager’s VP Freeze columns, native and DXF. ✅
PSLTSCALE (dash scale by viewport zoom)	Dashes read the same across scaled viewports.

H. Inquiry and drawing housekeeping — #30

Item	Priority
DIST / AREA / ID / LIST	Done (#30) ✅
PURGE / AUDIT	Done (#30) ✅
UNITS (drawing units + precision)	Done (#30) ✅
GROUP	Done (#33) — GROUP / UNGROUP / PICKSTYLE. ✅

I. Interop gaps — #31

(All stated honestly in the import result string today, never silently dropped.)

Item	Priority
DXF SPLINE / legacy POLYLINE import	Done (#31) ✅
DXF TOLERANCE (GD&T) export/import	Done (#31) ✅
DXF IMAGE / IMAGEDEF	Done (#31) — with object handles, CLASSES and the image dictionary. ✅
True SHX shape-file parsing (today: faithful substitution)	P2

J. Properties, snapping and input — #32

Item	Priority
PR numeric geometry editing	Done (#32) — Start/End, Center/Radius and Position fields edit the entity. ✅
OSNAP settings dialog; apparent intersection / insertion / parallel snaps	Done (#32) ✅
Input dialogs for Rotate/Scale + live ghost preview	Done (#32) ✅

K. Platforms — #1, #2, #4, #5

Item	Status
MSVC /W4 clean, warnings as errors on Windows	Done (#5) ✅
DWG inside the Flatpak	Done (#4) — an opt-in to a converter installed on the host. ✅
Flathub submission	Manifest (org.musacad.MusaCAD, the reverse of musacad.org), metainfo and linter run prepared (packaging/flatpak/BUILD_FLATPAK.md); the PR asks for the home-filesystem exception. P2
macOS	The workflow publishes a .dmg and the command line works; the viewport needs OpenGL 4.5, which macOS does not have, and the app says so at startup — a Metal or GL 4.1 render path is the prerequisite (packaging/macos/BUILD_MACOS.md). P2

Ordering rationale

P0 first, and within P0 the dimension-editing pair leads, because a drafter hits “I need this dimension to read <> H7” and “I need to move this text off the geometry” on essentially every real sheet, and neither has a workaround that keeps the dimension trustworthy. Tables come next (every fabrication sheet has a BOM or revision block), then block authoring and paper space, which are larger structural pieces.
