// Core Features

Everything you need
to design professionally.

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.

Live 2D/3D Canvas

Draw, extrude, and visualize your models in real-time. Switch instantly between orthographic and perspective views with a single keystroke.

[F-01]

Parametric Design

Change one dimension and watch your entire model update automatically. Build designs that are smart, flexible, and always accurate.

[F-02]

Real-Time Collaboration

Work on group projects with classmates simultaneously. Comment, annotate, and iterate together — no matter where everyone is.

[F-03]

Stress & Load Analysis

Run basic FEA simulations directly in the browser. Visualize force distribution and weak points in your structural designs before physical build.

[F-04]

Multi-Format Export

Export to DXF, STL, SVG, PDF, and more. Your designs are ready for 3D printing, laser cutting, CNC, or submission in one click.

[F-05]

Built-In Curriculum

150+ guided exercises aligned to STEM and engineering syllabi. Students learn by doing, with hints and auto-grading built right into the platform.

// Workflow

From zero to design
in four steps.

01

Sign Up Free

Create your student account in under 60 seconds. Use your school email for instant access to all curriculum packs.

02

Choose a Template

Pick from 200+ project templates — bridges, mechanical parts, architectural floor plans, circuit boards, and more.

03

Design & Iterate

Use the full CAD toolkit to build your design. The guided hints system helps when you're stuck — never leaving you stranded.

04

Export & Share

Submit to your teacher, download for fabrication, or share your portfolio link — all in one click from the dashboard.

  • Constraint-based sketching keeps geometry accurate — dimensions drive the design, not the other way around.
  • Snapping & alignment guides make it easy to draw precisely without needing to type every coordinate manually.
  • Part library with 10,000+ components including standard bolts, motors, gear profiles, and architectural elements.
  • Version history & auto-save means students never lose work, and teachers can review every iteration of a project.
  • Keyboard shortcut system designed to mirror industry-standard CAD tools, preparing students for the real workplace.
  • Accessibility mode with high-contrast UI, screen reader support, and adjustable canvas zoom for all learners.

Trusted by students
and educators worldwide.

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.
