The software automatically assigns fold lines based on the dihedral angle of the 3D mesh. Version 603 introduces a smarter default threshold for what constitutes a mountain fold (convex) vs. a valley fold (concave). Users can now adjust this threshold in real-time via the Settings > Fold Angle menu, reducing the manual cleanup required after unfolding.

Installing Pepakura Designer 603 is straightforward, but there is a crucial distinction between the free version and the licensed version.
