Features

From text to real CAD — with a Feature Tree

Mecasty turns engineering intent into structured parametric geometry (IGS v2), previews it in 3D, and exports a SolidWorks-native macro you can edit.

The workflow

Prompt → Parametric → Production

A consistent pipeline that’s fast to iterate and designed for engineering edits.

01 — Describe

Write dimensions, features, constraints, and intent in plain English. Mecasty extracts what matters for CAD.

02 — Generate

The AI outputs a versioned, structured IGS document. It’s not a mesh — it’s editable intent.

03 — Preview

Validate geometry in-browser before exporting. Catch obvious issues in seconds.

04 — Export

Download a SolidWorks VBA macro that builds a real Feature Tree you can edit like normal CAD.

What you get

Built for real CAD workflows

Not a demo. A pipeline that’s designed for editing and export.

AI GENERATION

Describe. The AI builds.

Write engineering intent in plain English — dimensions, features, tolerances — and Mecasty generates editable parametric CAD.

  • Engineering-language understanding
  • Unit conversion + dimensional accuracy
  • Feature inference (holes, fillets, patterns)
  • Material/tolerance-aware generation

PARAMETRIC

Real parameters. Not pixels.

Models are built from a structured schema (IGS v2). Every dimension is a parameter; edits propagate through features.

  • IGS v2: structured CAD intent
  • Constraints + relationships
  • Feature-level operations
  • Predictable production outputs

3D PREVIEW

Inspect before export.

Validate in-browser with a real-time viewer. Rotate, zoom, and catch issues early.

  • Instant WebGL rendering
  • Wireframe + solid modes
  • Review without downloads
  • Fast iteration loops

SOLIDWORKS

Native macros. No plugins.

Export a SolidWorks VBA macro that builds a real Feature Tree — sketches, extrusions, fillets — all editable.

  • Native .SWP macro output
  • Editable Feature Tree
  • No add-ins required
  • Stable API calls

Comparison

Mecasty vs. manual CAD

The goal is the same: production-ready parts. The path is radically different.

Mecasty

Automated, parametric, export-ready

  • Prompt-first workflow designed for iteration
  • Parametric outputs built for editing
  • Browser preview before export
  • Native SolidWorks macro generation

Manual process

Slow, repetitive, hard to standardize

  • Sketch, constrain, and dimension by hand
  • Context switching across menus and dialogs
  • Long setup for repetitive parts
  • Harder to standardize across teams
