Three dimensions, one rectangle, zero agreement. This tee is the sketch-error pop-up every CAD user has stared down, complete with the only button anyone ever clicks: NO, I'M RIGHT. Tolerance Stack makes shirts for the people who live in sketches and feature trees: design engineers, drafters, students and the machinists who get the drawing afterward.

What you get

  • Front: Small left-chest TOLERANCE STACK wordmark under a reference dimension with a warning triangle and "Sketch error · over-defined" (about 4 in)
  • Back: OVER-CONSTRAINED in big mono type over a dimensioned sketch rectangle with constraint tags, conflicting reference dimensions and orange error triangles, a SKETCH ERROR dialog box with DELETE ONE and NO, I'M RIGHT buttons, and the line "Just like my schedule."
