This simple add-on automates the non-destructive cutting of procedural panel lines, making it a game-changer for hard-surface models like cars, ships, and aircraft. It allows you to dynamically assign panel cuts without permanently altering the model's topology.
It's also very easy to use: choose the set of edges where you want to create panel lines, right-click to open the menu, and select the Panel Cutter tool. By default, this tool will create basic panel cuts without support loops for subD.
To add them, you can either increase the bevel segments or enable the subdivision checkbox. To add more edges to the panel lines, simply select the additional edges and run the tool again.
