DCC Tool Plugin Interface

Autodesk Maya Plugin

Import IGES / STEP files directly from the Maya menu. Converted polygon models are loaded into the scene as tessellated meshes, ready for animation and rendering workflows.

Unity Plugin

Install as a Unity package and add CAD data directly as assets. Tessellated models are immediately available in scenes, accelerating XR and real-time content production workflows.

Blender Add-on

Adds “IGES/STEP (CADChum)” to the File → Import menu. Import CAD data instantly with a single click, achieving high-precision conversion even in open-source environments.

Unreal Engine Plugin

Import CAD data directly within Unreal Editor. Use tessellated models as static meshes, ideal for architectural visualization and virtual production.

Batch Interface

CADChum Console	Supports batch export in OBJ format

Use Cases

3D Content Creation

Convert CAD data into high-quality polygon models for use in video, games, XR, and other 3D content production within DCC tools.

Real-Time Visualization

Enable real-time visualization, product reviews, and presentations through seamless integration with game engines.

Simulation & DX

Ideal for digital twin and simulation workflows. Supports efficient data conversion and optimization for DX initiatives.

System Requirements

CADChum Core	.NET Framework 4.7.2
CADChum Console	.NET 8.0 Runtime
