Short on time? Here's the quick answer
We've tested both tools. Here's who should pick what:
OpenSCAD
The programmer's solid 3D CAD modeller for creating precise 3D objects.
Best for you if:
- • Creates solid 3D CAD models using a script-based approach.
- • Focuses on technical design for machine parts, not artistic modeling.
BRL-CAD
Open-source solid modeling system for unambiguous 3D geometry and high-performance ray-tracing.
Best for you if:
- • Open-source, cross-platform solid modeling system.
- • Features hybrid CSG/B-REP kernel and high-performance ray-tracing.
