MCad keeps the commands, aliases, shortcuts and command line you already know: LINE, PLINE, OFFSET, TRIM, HATCH, DIM, BLOCK, LAYER… The interface is bilingual English – Vietnamese, it reads and writes DWG/DXF, works across Model and Layout, and prints proper vector PDF. Licences start at $25 — cheap enough to put every seat in the office on legal software.
MCad is a 2D design program for Windows, written by Vietnamese engineers for the daily work of architects, structural and MEP engineers, interior designers and students. The goal is deliberately narrow: keep the way you already work in AutoCAD, open the drawings your clients send, and bring the price of a licence down to what any office can afford.
The whole ribbon, every tool panel, dialog and command prompt exists in English and in Vietnamese; switch whenever you like under Help → Language. Typed command names stay international either way, so muscle memory carries over and a mixed team can share the same drawings and the same shortcuts.
The same command names and aliases (L, PL, O, TR, EX, H, DIM…), the same command line, OSNAP/Ortho/Polar, F3–F12, layers, blocks, hatches, dimensions, Model/Layout and plotting. Open the DWG/DXF a client sends, edit it, then save AutoCAD 2010/2018 or issue a vector PDF. Anyone who has used AutoCAD is drawing productively on the first day.
From $25 for three months, $40 for a year, or $50 for three years (just $17 a year) — each key runs on 2 machines. Pay by PayPal or card. A firm can put an entire design department on properly licensed software for a fraction of one foreign CAD subscription, with invoices and a per-account licence record for the paperwork.
MCad checks for a new build after startup and shows a small status-bar alert; you choose when to download and install it. Every plan receives free updates for its whole term — 36 months on the 3-year plan — and the product keeps moving with feedback from the people using it.
Under Vietnamese intellectual-property law a company must use properly licensed software in its commercial work; breaches carry administrative fines and damages. Plenty of small design offices still run unlicensed copies for one reason only — subscription pricing they cannot justify.
MCad exists to remove exactly that obstacle: a 2D CAD set that covers architectural, structural and interior documentation, licensed for the price of a takeaway lunch, with invoices and a transparent per-machine licence account. A ten-seat office can go fully legal for less than a single foreign CAD subscription costs in one year.

Two dedicated tabs for the furniture library and electrical symbols — drop in furniture, fixtures, sockets and lights at the right scale and rotation instead of hunting for loose blocks.
Current, recent, favourite and library blocks with previews and Insert/Replace. One External References panel manages DWG Xrefs, raster images and PDF underlays: inspect path and status, Zoom, Reload, Repair Path, Load/Unload or Detach.
Lisp Studio for writing and running scripts; APPLOAD manages the list of .lsp files loaded at every start, with a review step before anything is enabled.
Model/Layout tabs at the foot of the canvas; rename, copy and order tabs, move objects with CHSPACE, and switch viewports on or off. Save DWG 2010/2018, print to Windows, export vector PDF and Publish sheet sets.
Alongside the standard CAD command set, MCAD includes architectural objects with real data for faster floor plans and schedules. The Architecture tab in 0.88.71 includes walls, doors, windows, sliding and glass doors, rooms, columns, stairs, style sets, finishes, schedules and drawing symbols. Plain 2D geometry remains fully available; the architectural layer adds a specialist workflow without locking you into it.
Draw justified to the left face, centreline or right face; as a two-corner rectangle; or as a closed perimeter dimensioned to the inside, centre or outside face. L, T, X and skew junctions clean themselves up, and each layer of the build-up carries its own material and hatch. One command converts clean lines and polylines into walls.
WALLWALLCONVERTWALLJUSTIFYWALLTHICKNESSWALLCLEANUPOpenings belong to their host wall and are never orphaned. Single and double swing, sliding, glazed; the Door Type builder previews the leaf before you commit; pick the leaf itself to flip the swing, change the width or re-host it to another wall. Door schedules read the real data, not a typed list.
DOORWINDOWSLIDINGDOORGLASSDOORDOORFLIPOPENINGRESIZEOPENINGREHOSTClick inside a closed area to create a room, numbered as you go, named and styled.

WALLLENGTHWALLMOVEWALLERASEOPENINGSCHEDULEA plan drawn in MCad now carries straight on to the next stages without exporting to other software: reinforced-concrete beam design, electrical and plumbing layout, estimating and quotations, and CNC panel cutting. All of it is included in the same licence — no extra modules to buy.
Under Structural ▸ Structural project: multi-storey projects with one calculation per beam. Rectangular and T-beams with a compression flange, two reinforcement layers; cracking, deflection, anchorage, laps and bar curtailment; a search for a workable bar layout. Produces the beam reinforcement drawing (elevation and bar schedule) and keeps it linked to the calculation.
Structural ▸ Structural projectHelp chapter 21One standard layer per electrical or plumbing system. Wall-mounted devices follow their wall when it is edited, space evenly along a wall face, copy to other rooms and take mounting heights in bulk. Draw wiring runs, LED cove lights and pipes; dimension and annotate devices; split one plan into ceiling, switch and socket sheets with a legend of the real symbols.
MEPWIREMEPPIPEMEPELEVMEPROOMCOPYMEPSHEETMEPLEGENDWalls, slabs and finishes are measured by material straight from the drawing; wall heights follow the storey levels; cabinets, shelving and beds take area and sheet count from the panel-cutting job.

ESTIMATEESTIMATETABLEESTIMATEXLSXESTIMATEPDFExtract parts from furniture drawings, nest grained and rectangular panels, V-carve and relief-carve. Toolpaths follow the measured board thickness; machine profiles carry feed limits and Z origin; operators get a Vietnamese setup sheet and edge-banding labels; approved programs go straight to the folder the machine reads. A cabinet that is a dynamic block is cut at the size you stretched it to.

BSTATIC flattens safely before you send a file, BSYNC merges duplicates, and BSEARCH finds rotated and rescaled copies.

The point of MCAD is not to pile commands into an Architecture menu. It is to always show you what you are working on, what the sensible next step is, and what a change is about to affect.
When you already have site dimensions, a structural grid, or target clear spans.
AXISGRID and COLUMNGRID.When a client's drawing arrives, or plain CAD has to become objects with meaning.
WALLCONVERT; redraw anything ambiguous as a wall.When a partition moves, a room resizes, a door changes, or the stair core shifts.
MOVE, WALLLENGTH, WALLTHICKNESS, OPENINGRESIZE, DOORFLIP…ROOMUPDATE.MCAD does not try to recognise a whole floor plan with AI, and it will not silently turn every line into a wall. Anything uncertain is handed back to you to decide — the software never invents architecture on your behalf.
MCAD's own format. Keeps the full meaning of walls, doors, rooms and stairs, along with styles, catalogues and schema version history. Saved by write-temp → verify → back up → atomic replace, with an autosave every 2 minutes.
Exchange with any other CAD. Semantic objects are flattened to standard geometry with a clear report of the meaning that could not travel with them.
Open, edit and save AutoCAD 2010/2018. Layouts, tab order, page setups, viewports, paper rotation and Paper Space objects are checked across DWG → MCD → DWG conversion.
Sharp vector PDF with correct lineweights and plot styles, straight from a layout with its page setup, and Publish for multi-sheet sets in the saved order.
An interpreter for a working subset of AutoLISP: defun, setq, while, foreach, cond, wcmatch, plus geometry and string functions. A C:name function becomes a command for the session; load a .lsp file or type straight at the command line. Numbers, angles and options supplied from Lisp go through the same command pipeline as typed input.
.maplugin packages are signed with ECDSA P-256, installed per user, and run in a fault-isolated host with time and memory limits. The API registers commands, reads a drawing snapshot, and writes batched edits that are validated and then committed as one transaction. A faulty plugin is contained; it cannot take MCAD down.
Claude and other MCP clients can read drawings and Block/Room/Opening/Finish schedules, then create or edit geometry, layers, walls, openings, page setups and viewports. Every write batch is validated and committed atomically with Undo/Redo; the bridge can be switched on or off in Options.
TOWNHOUSEPLAN builds a complete 14,200 × 10,300 mm townhouse plan — 18 walls, 19 openings, columns, stairs, rooms, dimensions and furniture — using the very commands you use by hand. It is also the drawing at the top of this page.

The latest verified gate runs the full suite, produces warning-free Release builds, passes 11/11 health checks and completes clean transitive vulnerability scans before packaging.
Snapshots are written through exactly the same verification pipeline as a real save. After a crash MCAD offers Recover / Discard / Later, and the recovered file is marked unsaved so it can never be mistaken for the original.
Your drawings stay on your machine: activation sends only the licence key and a machine ID. A support bundle from the Diagnostics Center contains metadata only. Safe Mode disables plugins and hardware acceleration when needed, and updates are SHA-256 verified before they install.
Not everywhere — MCAD concentrates on 2D architectural drawings and does that part well for a one-off price. The table states the limits as plainly as the strengths.

Yes. MCAD opens DWG through an isolated worker and supports blocks, hatches, MTEXT, dimensions, layers, linetypes, layouts and Paper Space; you can save AutoCAD 2010/2018, read and write DXF, or export vector PDF. MCD remains the native format for full architectural semantics and controlled compatibility history.
When the .mcd format grows (for example to hold dynamic blocks or links to structural calculations), an older MCad says clearly that the file is newer and declines to open it — nothing is damaged or lost. New versions always open every older .mcd. Offices with several machines should update together; to send a file to a machine that has not updated, save it as DWG.
No. MCAD keeps the same command names and aliases (L, PL, TR, EX, O, F…), the command line, Dynamic Input, OSNAP/Ortho/Polar and F3/F6–F12. The only new material is the architectural commands such as WALL, DOOR and ROOM, each with its own guide.
With PayPal, using the button shown after you choose a plan — you can pay by Visa or Mastercard there without a PayPal account. We confirm during business hours (GMT+7) and the key appears in your account and your inbox. Companies needing an invoice should enter the company name and tax ID under Profile, or contact support.
Because a full-featured trial is available first, paid plans are not refundable once the key has been activated. If it has not been activated within 7 days of payment, we refund in full. See the refund policy.
MCAD checks at startup and shows a small status-bar alert when a new build is available; you choose when to download and install it. Updates are free for the whole term of a 3-month, 1-year or 3-year plan. Customers who bought a lifetime licence earlier keep their lifetime updates.
No. MCAD runs entirely on your machine; only licence activation contacts the server, sending the key and a machine ID. A diagnostic bundle, if you choose to export one, contains metadata only — never drawing content.
MCAD checks for a newer version after startup and shows a small status-bar alert only when one exists — no dialog and no stolen focus. You choose when to download and install it. Updates are free for the whole term of your licence.
