About:
CAD Assistant is an open-source 3D viewer and converter designed for handling complex CAD and mesh file formats. It leverages the Open CASCADE Technology kernel to provide robust visualization and translation capabilities without requiring a full CAD system. The tool enables users to inspect, measure, and convert models between various industry-standard formats efficiently.

Key Features:

Supports numerous CAD and mesh formats (STEP, IGES, STL, OBJ, BREP, XCAF)
Integrated 3D visualization with measurement tools
Batch conversion capabilities for automation
Cross-platform GUI built on Qt
Powered by the robust Open CASCADE kernel

Use Cases:

Converting legacy CAD models to modern formats for interoperability
Quickly viewing and inspecting large 3D models without launching heavy CAD software
Extracting geometry data for simulation or 3D printing workflows

Alternatives:

FreeCAD – Full parametric CAD suite; heavier and more complex than CAD Assistant's focused viewer/converter role
MeshLab – Specialized for mesh processing; less focused on native CAD format support
