Leqad is an independent browser-extension prototype exploring contextual CAD lessons, starting with Onshape. The goal is to help learners understand their modeling decisions as they practice.
Guided CAD practice
Try an eight-step exercise: choose a plane, draw and dimension a rectangle, then preview a 3D extrusion.
Try the interactive demoInteractive browser simulation · Separate from live CAD
A first-sketch walkthrough makes the modeling decisions visible, one step at a time.
Practice a guided first-sketch exercise, one modeling action at a time.
Reveal a hint or highlight a supported tool when you need a pointer.
Learn why reference planes, dimensions, constraints, and modeling choices matter.
An early browser-extension learning-assistant prototype targets Onshape. The website demo is a separate eight-step simulation of sketching and extrusion, including the preview shown above.
The simulation offers guided first-sketch practice, contextual hints, tool highlighting, and explanations for key modeling decisions.
Live Onshape compatibility remains unverified. The extension does not verify CAD geometry, and the website demo is not connected to a live CAD document.
Generalized design understanding and learning improvements from real user studies have not been demonstrated.
Expanded exercises, improved feedback and contextual learning, and educator evaluations are planned. Delivery depends on technical validation and feedback.
Broader technical capabilities, including help with troubleshooting and reasoning about designs, are a longer-term goal.
Leqad grew from challenges encountered while learning and teaching CAD. Its founder has experience in high-school robotics and leads and helps train newer robotics students.
The mission is to make technical learning more approachable and effective, so students understand what they build and become more independent with engineering tools.
We welcome exploratory conversations with educators and CAD platform teams about technical fit and useful learning evaluations.
