The Rocket Design Software for UKROC Teams
Design smarter, fly higher — with SpaceCAD. Visual design, instant flight simulations, 800+ real-world parts, and no subscriptions. Built for students. Trusted by teachers. Ready for competition.
Built for Education
Designed for the classroom. SpaceCAD is made with students and educators in mind — intuitive enough for beginners, powerful enough for advanced users. It helps teach rocketry concepts through hands-on, visual learning.
Accurate Physics, Trusted Results
Reliable simulations you can trust. SpaceCAD uses proven physics models to predict altitude, stability, and landing – helping teams design rockets that perform exactly as expected on launch day.
Faster to Learn, Easier to Use
No steep learning curve. With its visual interface and real-time feedback, most students are productive in minutes — no technical background required.
Experiment Freely
Try out variations, fast. Clone designs, swap engines, change fins — and instantly see the results. Perfect for testing different configurations before committing to a physical build.
Many Elements Supported
Add your own parts. Need a special payload bay or custom recovery system? SpaceCAD lets you define your own rocket elements for ultimate flexibility.
Trusted by UK Teams
Used in UKROC and beyond. SpaceCAD is already trusted by schools and competition teams across the UK. Built by a European developer, it’s ready for the needs of UK rocketry teams.Why choose SpaceCAD?
Design visually, not through menus. SpaceCAD lets you build rockets directly on screen using a powerful 2D designer. Just click and resize parts — no need to open complex dialogs like in Rocksim or OpenRocket.
Instant feedback, smarter design. See real-time updates to your rocket’s stability, altitude, and flight performance as you edit. This makes it faster and easier to find a design that flies safely and meets competition goals.
From design to flight in a single click. Unlike other tools where simulation feels like a separate process, SpaceCAD shows you flight results instantly — no setup, no switching views, no waiting.
Ready-to-use parts library. SpaceCAD includes over 800 real-world rocket parts — nose cones, body tubes, engines, and more — from trusted manufacturers like Estes, Quest, Centuri, and others. No guesswork, just accurate components.
Jumpstart your design. Get inspired with a collection of ready-to-fly rocket designs included for free — perfect for learning, exploring ideas, or getting started quickly.
