CADaddy 0.7.9

CADaddy 0.7.9: updates that work, IME and vertical text, the clipboard with other programs, our own DWG reader and writer, Sheet Set Manager II, everyday AutoCAD commands, and a long list of fixes from testing.

On 0.7.7 or 0.7.8? Please download this version by hand, once. Those versions don't offer updates with default settings, and on Windows their installer step never ran. 0.7.9 fixes both, so from here on CADaddy updates itself again.

Downloads

• Windows 10/11: CADaddy-Windows.msi
• Mac (macOS 11+, Apple chip and Intel): CADaddy-Mac.dmg — or brew install --cask aicodeforgedev/tap/cadaddy
• Linux: CADaddy-Linux.AppImage (any 64-bit distro from 2022 on) or CADaddy-Linux.deb (Ubuntu 22.04+, Debian 12+)
• Claude Desktop extension: CADaddy.mcpb

Updates and security

• Updates work again: the update card shows with default settings, Windows installs the update on Restart Now, and the card sits above the support banner. Updater messages are in your interface language.
• Updates are signed (SHA256SUMS + signature); tampered, truncated, unsigned, wrong-key and downgrade releases are refused and leave your copy untouched.
• Image, font and hyperlink paths can't point at other computers' shares (no password-hash leaks on Windows); disguised links to programs ask first.
• Agents can't loosen trusted locations, the control-port token or their own confirmations; agent batches go through the same safety rails; MCP requests are size-limited.

Drawing and editing

• Typing Chinese, Japanese and Korean at the command line and in the MTEXT editor, with the candidate window at the caret; vertical text styles drawn and plotted.
• The clipboard with other programs: Paste Special (as objects, picture or text), copies carry a picture for documents and email, and pasting another program's picture or text works.
• Everyday commands: OOPS, MULTIPLE, COPYTOLAYER, CUTBASE, DIMCENTER, SOLID, FILL, QTEXT, VPMAX/VPMIN, FILTER, ATTREDEF, DXFIN/DXFOUT, UCSMAN, SETBYLAYER, XPLODE, VPSYNC, ATTIPEDIT; Express Tools IV; MEASUREGEOM Quick.
• BREAK opens closed polylines, ellipses and splines, and a command that can't act no longer traps what you type next.
• Undo: one undo undoes an agent's whole batch; a refused command leaves no empty step; redo keeps associative dimensions.
• 2D drawings from solids (SOLVIEW, SOLDRAW, SOLPROF); 3D Building from Plan puts doors in their openings; ROOMS follows the walls and room tags.
• A hint when new dimensions or text would be too small to read at the drawing's scale.

Files

• CADaddy's own DWG reader and writer (R2000 to R2018) alongside the existing one, checked against independent readers; complex linetypes, block descriptions and non-English text now survive DWG 2000/2004.
• Raster export (PNGOUT, JPGOUT, TIFOUT, BMPOUT) and raster plot devices; IFC export with stacked storeys, openings and stable IDs.
• Sheet Set Manager II: docked, with custom properties, page setup override, views, callouts and fields; new sheet sets save as .sheetset.json; new layouts get a viewport fitted to the drawing.
• The Release 12 and multileader save notes now say what actually happened; Save As no longer writes your command history next to exported files.
• Drawing properties (DWGPROPS) and script tools (SCRIPTCALL, RSCRIPT, DELAY, RESUME); damaged-DWG recovery (RECOVERALL).

Interface

• Count palette from Tools ▸ Count; MARKUPIMPORT on the Insert ribbon; prompt defaults in your drawing's units; palettes open clear of the ribbon.
• The first window fits high-DPI screens; drawings open framed above the command line; menu symbols show on Windows.
• Touch taps pick and place points; Select Color keeps a typed hex value.
• Interface in Traditional Chinese, Polish, Hungarian and Turkish.

CADaddy 0.7.8

CADaddy 0.7.8: a .cdy ⇄ DWG converter, a security round, IFC export, IMAGETRACE, the Count and Select Color palettes, touch and pens, and tear-off drawing windows.

Downloads

• Windows 10/11: CADaddy-Windows.msi
• Mac (macOS 11+, Apple chip and Intel): CADaddy-Mac.dmg
• Linux: CADaddy-Linux.AppImage (any 64-bit distro from 2022 on) or CADaddy-Linux.deb (Ubuntu 22.04+, Debian 12+)
• Claude Desktop extension: CADaddy.mcpb

Installed copies of 0.7.5 and later offer this update on their own.

Files

• .cdy ⇄ DWG converter in the app, and cadaddy-cli converts whole folders and plots a folder to PDFs.
• DWG keeps more of what other programs wrote; multileaders round-trip; exchange notes list what a DWG/DXF save couldn't keep, feature by feature.
• IFC export; Redline markups; .cdy carries the 3D model (meshes, textures, lightmap, tours); Publish Walkthrough makes a package the web build opens straight into Walk.
• Big drawings: million-object drawings, .cdy and large DXF files read on all cores, faster startup.

Drafting and tools

• IMAGETRACE: raster plans to lines, arcs, circles, wall pairs and text boxes.
• Count palette (block counts, highlight and zoom, similar copies, live count tables) and Select Color (HSL/RGB sliders, hex, Color Books).
• Purge dialog with a per-item tree; TEXTALIGN; Quick Properties and multi-edit of mixed selections; layer tools (LAYWALK, LAYVPI, viewport overrides).
• PLOTSTAMP with its dialog, and batch plotting; geographic location (GEOGRAPHICLOCATION, LATLONG); DIMREGEN; text masks over hatches and images.
• AutoLISP DCL dialogs; custom user interface files; an action recorder.

Interface

• Touch screens and pens: pinch, two-finger pan, long press, a touch bar.
• Tear-off drawing windows: drag a drawing tab out into its own window.
• Arabic: dialog contents now mirror right to left too.
• File names ignore case and accept backslashes everywhere.

Security

• Signed updates: each release carries SHA256SUMS and its signature; the updater checks both before installing.
• The control port and the MCP connector are locked down; hyperlinks, xrefs and packages can't be used against you; AutoLISP and scripts load only from trusted locations.
• The file readers are hardened and fuzzed; SECURITY.md explains how to report a problem; PRIVACY.md lists every request CADaddy makes.

For agents

• drawing_summary and drawing_query for unfamiliar drawings; execute_many runs many commands as one undo step; watch_events streams what happens in the app.
• Safety rails: one undo step per request, dry runs, confirmations and a change journal.

Fixes

• BOUNDARY and AUTOCONSTRAIN no longer stall on busy drawings.
• Commands an agent types now show in the command history.
• Find and Replace fields are named for screen readers; the .cdy preview builds fast on densely hatched plans.

CADaddy 0.7.7

CADaddy 0.7.7: 3D and walkthroughs, CADaddy's own .cdy format, sheet sets, plans-to-model, and hundreds more AutoCAD commands and options.

Downloads

• Windows 10/11: CADaddy-Windows.msi
• Mac (macOS 11+, Apple chip and Intel): CADaddy-Mac.dmg
• Linux: CADaddy-Linux.AppImage (any 64-bit distro from 2022 on) or CADaddy-Linux.deb (Ubuntu 22.04+, Debian 12+)
• Claude Desktop extension: CADaddy.mcpb

Installed copies of 0.7.6 offer this update on their own.

3D and walkthroughs

• 3D solids: primitives, extrude/revolve/sweep/loft, booleans, fillets, SOLIDEDIT, SLICE; sections and elevations; 3D move/rotate/scale/align/mirror/array with gizmos, 3D snaps and dynamic UCS.
• Materials, lights and the Realistic style, a path tracer for still renders, and baked lighting (LIGHTBAKE) for walkthroughs.
• Walk and fly inside the drawing (View ▸ Walk) and camera tours with MP4 export.
• Big scenes stay fast: instancing, culling, level of detail and background builds; 3D works on weak and virtual GPUs with CPU fallbacks.
• 3D exchange: glTF/GLB, OBJ and STL export and import; point clouds (LAS, PTS, XYZ).

Plans to model

• A building spec kept in the drawing, drafted from the plan alone (bspec.draft) or from PDF plans, reviewed in the Plans to Model palette, then built: walls with openings, stairs/ramps/railings, exteriors and roofs from elevations, ceilings from reflected ceiling plans, rooms as 3D spaces, MEP runs with a clash report, structural grids, door and window schedules, and furniture from the plan's 2D symbols (FURNISH).
• model.revise rebuilds after the plans change and keeps hand edits.

Files

• .cdy, CADaddy's own lossless format (save as .cdy) with fast incremental saves.
• Release 12 DXF output; EPS and WMF export.
• Other programs' handles are kept across saves; binary .ctb/.stb plot style tables and system printers.
• Sheet sets (Sheet Set Manager, publish to one PDF with bookmarks); plot preview shows the real plot; PUBLISH sheet lists.
• Markups from reviewed PDFs (MARKUPIMPORT) as revision clouds and text; Excel data links and TABLEEXPORT to .xlsx; searchable text in PDF plots.
• eTransmit; edit xrefs in place; plot from the command line.

Drafting

• Fields, UCS, spell check, hyperlinks, dynamic block authoring, BLOCKIFY, Express Tools III and the text tools (SCALETEXT, TJUST, TORIENT, TEXTMASK, TCIRCLE, TEXTFIT, TFRAME, RTEXT, ATTOUT/ATTIN).
• Find and Replace; DesignCenter; Blocks palette and tool palettes; Undo History and Command History palettes.
• Tab cycles snap points; tracking shows every acquired point; command-line AutoComplete with named objects.
• CAD standards (STANDARDS, CHECKSTANDARDS, LAYTRANS); Parameters Manager and constraint settings.
• AutoLISP vlax-curve and vl- functions; about 80 more system variables.

Interface

• Accessibility: every control is named for screen readers, ribbon key tips, a High Contrast theme and an interface size setting.
• Workspaces and the navigation bar; an alias and shortcut editor; floating palettes on other monitors.
• Right-to-left interface for Arabic; Japanese; engine messages in every interface language.
• Report a Problem builds a diagnostics bundle on your computer (nothing is sent).

Fixes

• Saving DWG/DXF no longer gives two objects the same handle.
• Reopening a drawing that is already open moves it to the top of Recent Files.
• Agents can't press Enter inside a command you started.
• Many tester-reported fixes across commands, dialogs and palettes.

CADaddy 0.7.6

CADaddy 0.7.6: quantity takeoff, XCLIP, much faster work on dense hatched sheets, and CADaddy is now source-available.

Downloads

• Windows 10/11: CADaddy-Windows.msi
• Mac (macOS 11+, Apple chip and Intel): CADaddy-Mac.dmg
• Linux: CADaddy-Linux.AppImage (any 64-bit distro from 2022 on) or CADaddy-Linux.deb (Ubuntu 22.04+, Debian 12+)
• Claude Desktop extension: CADaddy.mcpb

Installed copies of 0.7.5 offer this update on their own.

New

• Quantity takeoff (TAKEOFF, Tools ▸ Inquiry ▸ Quantity Takeoff): lengths or areas by layer (wildcards allowed), with a waste factor, in feet or metres from the drawing's units. Blocks, arrays and xrefs are counted at their scale, and clipped references count only what they show. Output as CSV or a table in the drawing.
• XCLIP (Modify ▸ Clip ▸ Xref): clip block references and xrefs to a rectangle, polygon or polyline, inside or outside, with the frame shown per XCLIPFRAME. Clips are saved in DXF and DWG.
• Symbols land on trade layers (power, lighting, equipment, communications, fire alarm) with their schedule fields hidden, and remember the last values you typed.
• -DIMSTYLE and -STYLE at the command line; WBLOCK and MEASUREGEOM prompt for what they need; menu items that used to demand parameters now prompt.
• More AutoLISP: attributes are entities (ENTNEXT, NENTSELP), TBLOBJNAME, REGAPP and xdata (entget with application names, ssget filters), angles in radians, and DWGNAME/DWGPREFIX/DWGTITLED.

Faster

• Hatches with thousands of islands no longer slow everything down: on a dense civil sheet, a pick went from up to 6.5 s to about 0.1 s, and undo from 4 s to under 0.4 s.
• PEDIT Multiple Join works in linear time (thousands of segments in a moment), and picking a point inside a dense area to hatch is quicker.
• Selecting ALL is linear: moving 200,000 objects takes about a second.

Safer with your files

• Opening a drawing whose current linetype or text, dimension, multileader, table or multiline style doesn't exist resets it to ByLayer or Standard (with a note), instead of giving every new object a name the file lacks.
• Closing a drawing gives back its memory: cached selection indexes and decoded images of closed drawings are released.
• Relative image paths are looked up only beside the drawing that uses them, so two jobs with the same image names never show each other's pictures.
• Crash recovery offers a crashed session's files at once, without taking files from a copy of CADaddy that is still running.
• Dimensions inside blocks keep their geometry when saved; groups are saved with their member links.
• Enter pressed while the "save changes?" question is open no longer repeats the last command behind it.

Fixes

• The in-place multiline text editor keeps the keyboard (typing no longer replaced the text).
• Hatch boundaries on converted plans close where wall pieces overlap.
• ENTMOD keeps attributes and dimension associativity; Unicode escapes in text are decoded; FIND searches the decoded text.
• PDF import: markups stay on the page, and converted sheets take their dimension and text scale from the scale note.
• CEN snap from a circle's edge; fixed-height text styles skip TEXT's height prompt; -HATCH asks again for an unknown pattern.

CADaddy 0.7.5

CADaddy 0.7.5: an electrical symbol library, editing multiline text in place, and a fix that kept text masks from being lost.

Downloads

• Windows 10/11: CADaddy-Windows.msi
• Mac (macOS 11+, Apple chip and Intel): CADaddy-Mac.dmg
• Linux: CADaddy-Linux.AppImage (any 64-bit distro from 2022 on) or CADaddy-Linux.deb (Ubuntu 22.04+, Debian 12+)
• Claude Desktop extension: CADaddy.mcpb

New

• Automatic updates. From this version on, CADaddy checks once a day for a newer release. When one comes out, a small card offers to update; CADaddy downloads it, checks its SHA-256 fingerprint and installs it when you close the app (or right away with Restart Now). Help ▸ Check for Updates looks now, and Options ▸ Preferences turns the daily check off. Only the request for the latest version number goes out. On Linux this works with the AppImage; the .deb shows a download link.
• Electrical symbol library: 33 symbols drawn for CADaddy, in the Symbols palette next to plumbing.
  • Devices placed at your drawing's scale: duplex, quad, GFCI, weatherproof, dedicated and 208/240 V receptacles, floor box, single-pole, 3-way, 4-way and dimmer switches, occupancy sensor.
  • Lighting at real size: 2x4 and 2x2 troffers, downlight, wall sconce, strip light, exit sign, emergency light.
  • Power: panelboard, disconnect, transformer, junction box, motor connection, home-run arrow.
  • Low voltage and fire alarm: data, phone and TV outlets, smoke and heat detectors, horn/strobe, pull station, fire alarm control panel.
  • Devices have circuit, panel and mounting-height fields; fixtures a type tag and circuit; panels a name and voltage. Hidden trade and type fields let counts and schedules total them.
• Edit multiline text in place: double-click a paragraph of text to edit it right in the drawing, with its formatting kept.
• New drawings start with a viewport on Layout1 and Layout2, as in AutoCAD, so plotting a layout no longer gives a blank page.

Safer with your files

• Saving a drawing to a file that's open in another tab is refused. Before, it overwrote that drawing's work.
• Background masks on multiline text are kept when you open and save a drawing.
• AUDIT no longer deletes zero-length lines (they're valid and plot as dots).

For estimating and takeoff

• Data Extraction counts blocks inside arrays and inside other blocks, so a panel schedule built from arrayed or nested devices adds up.
• Typed architectural distances take the dash form: 6-1/2", 5'6-1/2".
• AREA and LIST report areas as square inches and square feet in architectural units (11520.0000 square in. (80.0000 square ft.)).

Fixes

• These commands now prompt when typed instead of reporting a missing value: COLOR, LWEIGHT, LTSCALE, LIMITS, BASE, FIND, GETVAR, LAYISO, LAYMCUR, LAYMCH, BREAKATPOINT. ABOUT, QUIT and EXIT work.
• PEDIT: pedit m all y j 0 joins lines into polylines, and selection words like L work at "Select polyline".
• A keyword typed at a selection prompt wins over Last/Previous: COUNT's L is List.
• Prompts no longer say "or or [...]".
• EXPLODE keeps layer 0 and ByBlock objects as defined, as AutoCAD does.
• Ortho and Polar tracking turn each other off.
• Turning off the current layer from a palette asks first.
• Command-line errors read as plain reasons.
• Stacked fractions no longer touch the number before them (20'-0 ½").
• An xref that doesn't load says why, including to AI agents.
• The command-line tool is now named cadaddy-cli, and its log file cadaddy.log. On Linux, settings live in ~/.config/cadaddy.
• The installers include the licence terms and third-party notices.

CADaddy 0.7.4

CADaddy 0.7.4: a plumbing symbol library, a Dimension Style Manager, and fixes from a second round of battle testing.

Downloads

• Windows 10/11: CADaddy-Windows.msi
• Mac (macOS 11+, Apple chip and Intel): CADaddy-Mac.dmg
• Linux: CADaddy-Linux.AppImage (any 64-bit distro from 2022 on) or CADaddy-Linux.deb (Ubuntu 22.04+, Debian 12+)
• Claude Desktop extension: CADaddy.mcpb

New

• Plumbing symbol library: 34 symbols drawn for CADaddy.
  • Fixtures at real size: water closets, urinal, lavatories, sinks, mop sink, tub, shower, drinking fountain, water heater, floor drain, floor sink.
  • Piping symbols placed at your drawing's scale: gate, ball, globe, butterfly and check valves, PRV, RPZ backflow preventer, cleanouts, union, cap, pipe up/down, meter, VTR, hammer arrestor, pump, hose bibb, flow arrow.
  • Each has a tag or pipe size to fill in, plus hidden trade and type fields so counts and schedules can total fixtures by type.
• Symbols palette: pictures of every symbol, a search box and click-to-place (Window ▸ Symbols, or Insert ▸ Symbols). You can also type SYMBOL.
• Dimension Style Manager: D, DIMSTYLE or Format ▸ Dimension Style. Unit format, precision, text, arrows, extension lines and overall scale.

Safer with your files

• Opening a drawing that's already open switches to its tab instead of opening a second copy.
• Saving over a DWG that CADaddy couldn't fully read now asks first, and keeps the original as a .bak. Every save keeps the previous version as .bak.
• A cut-off DXF opens with a warning instead of quietly missing objects.
• Read-only files aren't saved over, and saved files keep their permissions.

Fixes

• Architectural dimensions read 20'-0 1/2" (not 20'-1/2").
• A dimension style comes back intact after DWG save and reopen.
• Viewport layer freezes are saved where other CAD programs read them.
• Mirrored blocks keep their attribute text readable.
• Typing works after clicking a drawing, layout or ribbon tab.
• Typing into a Properties field replaces its value.
• Properties no longer changes objects on locked layers.
• Esc closes dialogs.
• The AI connector's control port closes connections that send junk, and xref paths pointing to other computers are refused.

CADaddy 0.7.3

CADaddy 0.7.3: now on Linux, plus a round of fixes from real-drawing testing.

Downloads

• Windows 10/11: CADaddy-Windows.msi
• Mac (macOS 11+, Apple chip and Intel): CADaddy-Mac.dmg
• Linux (new): CADaddy-Linux.AppImage for any 64-bit distro from 2022 on (make it executable and run it), or CADaddy-Linux.deb for Ubuntu 22.04+, Debian 12+ and Mint
• Claude Desktop extension: CADaddy.mcpb

Opening other people's DWGs

• Layouts that came up blank or off the sheet now show their sheet where AutoCAD puts it, including layouts set to millimetres in an inch drawing.
• Viewports that had been panned in AutoCAD now show the right part of the model.
• Saving no longer resets the drawing's dimension settings (architectural units, text and arrow sizes, alternate units and more).
• Attributes on layer 0 stay on layer 0 when you save.
• A tab in multiline text no longer turns into "^I" after a DWG save.

Drafting the way AutoCAD users expect

• COPY: the Array option (with Fit) and Undo now work.
• FILLET and CHAMFER: a radius or distance too large for the lines is refused instead of producing odd geometry.
• TRIM: after choosing cutting edges, an object that doesn't cross them is kept, not erased.
• DIMCONTINUE / DIMBASELINE: Enter lets you pick another dimension to continue from; a second Enter ends.
• OFFSET keeps polyline widths.
• HATCH: boundaries follow door swings inside blocks, and text gets a clear margin. -HATCH Pattern asks for the scale and angle.
• ATTDEF asks for text height and rotation.
• ORTHO typed at the command line asks ON/OFF (F8 still toggles).
• ERASE tells you when objects were skipped because they're on a locked layer.
• New commands: CHPROP, CHANGE, classic -ARRAY, LEADER at the command line, and QLEADER (LE).

Sturdier

• Opening something that isn't a regular file (or is huge) gives an error instead of eating memory.
• The AI connector (MCP) answers a garbled message with an error instead of shutting down.

CADaddy 0.7.2

CADaddy 0.7.2: exact curves

More accurate

• Snapping to where something crosses an ellipse or a spline (Intersection) now lands exactly on both, not on an approximation of the curve. The same goes for Nearest on ellipses and splines.
• TRIM and EXTEND against an ellipse or a spline end exactly on it.
• OFFSET of an ellipse gives a smooth spline (as AutoCAD does) instead of a polyline, and offsetting a spline stays true to the curve, within a millionth of its size.
