Software/DraftCore Mechanical
Parametric mechanical CAD for parts, assemblies and drawings — with sheet metal, frames and welds, mesh repair, machining and rendering built in. Runs fully offline on your Windows PC — and it’s free.

What’s inside
DraftCore Mechanical covers the everyday mechanical design workflow — and the work around it — in a single application.
Extrude, revolve, sweep, loft, fillets, chamfers, shell, draft, rib, holes, patterns and more. Reorder, roll back or insert features in the tree, or use Pull to drag a face, edge or sketch with a live preview.
Lines, arcs, splines, slots, polygons, text and blocks, with geometric constraints and driving dimensions that preview live as you place them.
Base flange, hem, jog, line bend and forming tools, with gauge and K-factor tables and a flat-pattern DXF that carries bend lines.
A standard profile catalogue — tube, pipe, angle, channel and beams — plus fillet welds, a weld table, gussets, end caps and a cut list.
Standard, cam, gear and slot mates, fasteners, exploded views, interference and clearance checks, motion simulation, and a lightweight mode for large assemblies.
Section, detail, auxiliary and broken-out views, GD&T, BOM, hole and weld tables, revision clouds, and an editable title block on A0–A4 and ANSI sheets.
Open STL, OBJ and PLY scans; check, repair, fill holes, remesh and sculpt; run mesh booleans; and convert fitted regions into an editable solid.
Milling, turning and wire-cutting toolpaths with material-removal simulation, cycle time and post-processed G-code. Check and simulate every program before cutting.
Physically based materials, studio lighting and soft shadows, image decals, PNG export up to 4×, and turntable video.
Finite-element studies of parts and assemblies — static, nonlinear, buckling, fatigue, vibration, impact, thermal and sheet-metal forming — plus live flow simulation. Results are a guide.
JavaScript macros with parameter forms, shareable add-on packages, and a local, key-protected REST API you can call from any language.
Version history, check-out / check-in, and a release flow from In Work to In Review to Released, with revision letters and notes per document.
Latest release
Version 1.0.5 brought bug fixes and a better offline AI assistant. Update to the latest from Help → Check for Updates.
Added in 1.0.3
Version 1.0.3 added a lot to the stress, vibration and flow tools, and tightened up sketching. Installed copies update from the Help menu in one click.
Choose what you want to find out — static, nonlinear, buckling, fatigue, creep, modal, harmonic, random vibration, transient, drop impact, thermal — and each simulation is saved with the part under its own name, with its set-up and last results. Export CSV, JSON, an HTML report or a video.
Hinge, slider, ball, planar, bushing and fixed joints between bodies, remote displacement, cyclic symmetry for one-sector models, and submodels that re-mesh a detail finer inside the whole-part result.
Split the stress through a wall into membrane, bending and peak, and assess a surface or through-wall crack with a failure assessment diagram and fatigue crack growth — the handbook method used in fitness-for-service work.
Simulate a punch, die and blank holder on a sheet: springback, thinning, strains and a forming limit diagram, with the punch force at full stroke.
Flow now starts with a smooth ramp, so a pipe no longer sloshes back and forth before settling. Rotating agitators and rotors work with two-phase and non-Newtonian liquids, and a new calculator and saved HTML report summarise flow, pressure drop and loads.
A full audit of the sketcher: trim, extend, mirror and drag now keep geometry joined, and relations work on several objects at once. Combine gains “split into regions”, there is a Ruled Surface, and you can hide the ribbon tabs you do not use.
From model to picture
The drill on this page was built as a revolved blank, a helix and swept flute cuts, then rendered in the same application — no export to a separate rendering tool.
Requirements
Get started
Get the 1.7 GB installer package (.zip) from the downloads page and extract it.
Run DraftCore-Mechanical-Setup-1.0.6.exe from the extracted folder. About 2 GB of free disk space is needed.
The app and its analysis tools install together. Add the offline AI assistant any time from the Assistant tab, and update in one click from the Help menu.
Questions
Yes. DraftCore Mechanical is free to use. Download it from the downloads page — there is no sign-up.
No. It runs on your own computer. Internet is used only to download the optional AI model once, and to fetch updates.
The installer is not code-signed yet, so Windows SmartScreen shows that warning. Choose More info → Run anyway. You can confirm the download is intact by comparing its SHA-256 on the downloads page.
Use Help → Check for Updates in the application. It also checks quietly when it starts and offers a new version when one is available. Your files are not touched.
The Assistant tab runs offline once you have added a model. The first time you open it you choose a model size to suit your computer, and the size is shown before you download.
Machining (CAM) and the simulation tools (stress, heat and flow) are marked Beta in the application. Treat their results as a guide and check them before relying on them.
Parts and assemblies export to STEP, IGES, STL, OBJ, PLY and glTF. Drawings export to PDF, SVG, DXF and PNG.
