S.A.T.D.I.S is the professional-grade CAD platform built specifically for students — powerful enough for real engineering, simple enough for day one.
From first sketches to final exports — S.A.T.D.I.S gives students the same toolset used in real engineering environments, without the overwhelming complexity.
Draw, extrude, and visualize your models in real-time. Switch instantly between orthographic and perspective views with a single keystroke.
Change one dimension and watch your entire model update automatically. Build designs that are smart, flexible, and always accurate.
Work on group projects with classmates simultaneously. Comment, annotate, and iterate together — no matter where everyone is.
Run basic FEA simulations directly in the browser. Visualize force distribution and weak points in your structural designs before physical build.
Export to DXF, STL, SVG, PDF, and more. Your designs are ready for 3D printing, laser cutting, CNC, or submission in one click.
150+ guided exercises aligned to STEM and engineering syllabi. Students learn by doing, with hints and auto-grading built right into the platform.
Create your student account in under 60 seconds. Use your school email for instant access to all curriculum packs.
Pick from 200+ project templates — bridges, mechanical parts, architectural floor plans, circuit boards, and more.
Use the full CAD toolkit to build your design. The guided hints system helps when you're stuck — never leaving you stranded.
Submit to your teacher, download for fabrication, or share your portfolio link — all in one click from the dashboard.
Every tool a working engineer uses — refined and documented for learners at every level. No steep learning curve required.
No hidden fees. No credit card required. Upgrade whenever your projects demand more power.
Everything you need to start learning CAD design from scratch.
The full platform for serious students and engineering courses.
For teachers and institutions. Manage your whole class from one dashboard.
I went from knowing nothing about CAD to designing a fully functional gear assembly in three weeks. The built-in exercises actually make sense — they feel like real engineering problems, not just abstract drills.
My whole class uses S.A.T.D.I.S now. The teacher dashboard is genuinely the best thing I've found — I can see every student's progress, leave comments directly on their designs, and set deadlines automatically.
The simulation tools are incredible for the price. I used the stress analysis feature for my final year bridge design project and got an A+. My professor was shocked I used a free student platform.
Join 47,000 students already using S.A.T.D.I.S to build their engineering future. No credit card. No commitment. Just great CAD.
