Questions
Box shape and lid
Pill, Polygon and Cylinder are Pro shapes; you can preview them on the Free plan.
Dimensions
All sizes are outside sizes, base and lid included. The corner radius matters most: the hinge has to bend round it, so a small radius needs a softer hinge. Bend Analysis checks it for you.
Hinge pattern
A living hinge is a field of parallel slits that lets a stiff sheet bend. Each bar between the slits twists a little, and hundreds of small twists add up to a curve.
Auto-fit picks the stiffest hinge that still reaches your corner radius with a 30% safety margin. Stiffer means fewer cuts, less charring and a stronger wall.
Bend Analysis
Bend Analysis works out the tightest radius the hinge can reach from the torsion-bar strain of your material, and compares it with your corners.
The minimum radius is an engineering estimate. Cut a bend test strip (Sheet section) in your own material before the whole box.
