🛠️ Design, Visualize, and Analyze

1. Design your rockets using a rich selection of built-in components:

2. Visualize your masterpiece in 3D:

3. Plot & Analyze your simulation results for precision and improvements:

🌟 Features

• Six-degree-of-freedom flight simulation
• Automatic design optimization
• Realtime simulated altitude, velocity, and acceleration display
• Staging and clustering support
• Export to other simulation programs (RockSim, RASAero II)
• Export component(s) to OBJ file for 3D printing
• Cross-platform (Java-based)

... plus many more
