cadi
Grade CAD assignments with a single answer model
CADI compares each student CAD model with the answer, scores it, and shows the differences in 3D. You review and release the final score.

Still opening student CAD files one by one to grade?
Time
Opening files one at a time leaves less room to prepare the next class.
Consistency
The same mistake can look different from student to student, which makes the rubric hard to explain.
Feedback you can point to
If a deduction is only described in words, students cannot see what to fix.
Scene 1
From assignment to released score, in one flow
Once the professor opens an assignment with the answer model, students submit right away. Each submission is graded automatically, and students see the score after the professor reviews and releases it. Professors can also bulk upload student files.
