Convert 2D engineering drawings to 3D CAD

Aibuild OS reads a 2D engineering drawing, reconstructs the 3D geometry inside your existing CAD software, including CATIA 5, Autodesk Fusion, Solidworks, Rhino, and exports as a STEP file or other formats. Your engineer reviews and approves the result.

Which CAD software does Aibuild OS work with?

Aibuild OS operates multiple engineering softwares, including Blender, Autodesk Fusion, Rhino, FreeCAD and MeshLab, with the list expanding continuously.

What output formats does Aibuild OS produce?

Aibuild OS operates your CAD software directly so it can also save in that application's native format, the model stays editable in the tool your team already uses.

STEP

The default for CAD output. Most CAM, CMM and inspection software uses.

2D / drawing formats

DXF, DWG, SVG, PDF. Including orthographic views, sections, dimensioned drawings.

STL

Binary or ASCII.

PLY

Used for point clouds.

BREP

OpenCASCADE native

3DM

Rhino native

FCStd

FreeCAD native.

Mesh / polygon formats

3D printing, visualisation, and downstream mesh tools.

OBJ

+ .mtl materials.

3MF

Printing with units, colour, and metadata.

G-code

Machine-specific toolpath files from slicing and use in Aibuild CAM.

Watch a 2D drawing turn into a STEP file with Aibuild OS.

Aibuild OS has the choice of the latest AI models from Anthropic, OpenAI, Google and other providers.

What an Aibuild OS pilot looks like.

Enterprise teams typically start with a scoped pilot supported by the Aibuild OS team.

Is Aibuild OS secure?

Aibuild Limited is ISO 27001 certified and available as an on-premise deployment for enterprise manufacturing environments. Drawings and derived geometry and all IP stay inside your own infrastructure.

FAQ

Can Aibuild OS convert a PDF drawing to a 3D model?

Yes.

You attach the PDF, and Aibuild OS read the drawing directly (views, dimensions, hole positions, features, title block info). From there you have two routes:

1. Parametric CAD model - Aibuild OS interpret the actual dimensions from the drawing and build real solid geometry, exported as a STEP file (or STL/other formats on request). This is dimensionally accurate and editable, and is the right choice for manufacturing.

2. AI 3D model - Aibuild OS generates a mesh (GLB) that visually resembles the drawing. This is good for a quick visual, but it's not dimensionally accurate.

Is Aibuild OS generated CAD accurate enough for manufacturing?

For clean drawings and standard features, the geometry is generally accurate. Tolerances, GD&T and material specifications require engineering review before use in production, which is why Aibuild OS routes every output through an approval step rather than sending it straight to a machine.

Does the model come out parametric or editable?

Yes, but the format you choose determines what you get. STEP and IGES export finished geometry, editable with direct-modelling tools.

The underlying model Aibuild OS builds is parametric, driven by named variables, so it stays editable through Aibuild OS indefinitely.

You can also ask for your CAD application's native format instead, which preserves the sketches and parametric history.

Do other Aibuild OS users have access to my drawings and CAD data?

No, your data and IP stay within your organisation and is never shared with or made accessible to other organisations.

Can Aibuild OS convert PDF, DWG or DXF drawings?

Yes. Vector PDFs exported from CAD, DWG and DXF all convert reliably where the views and dimensions are legible.

DWG and DXF are 2D vector formats, so the geometry is reconstructed rather than translated — Aibuild OS interprets the views and builds a solid model from them.

Scanned raster PDFs work, but accuracy depends on line quality and annotation legibility. Faded, hand-annotated or heavily revision-marked drawings are where results degrade.
