Bridge Curves
(by Ali Torabi)
Connects a given set of curves together by creating bridges between them. The bridges are created along the shortest path.

When you take off elements from a laser or CNC machine after cutting process ,sometime you want the items to remain connected together rather than mixing them up and spend time on sorting later on. If that is what you struggle with in your workshop, then we have Bridge Curve plug-in for you! The plug-in connects the element together by making small bridge between each pair. The elements remain connected till you break those tiny connections.     

Shortest path problem

The program uses an evolutionary algorithm to find the best possible sequence of the curves in which by connecting them the shortest path is achieved. In the other words the total length of the bridges are always minimized. In order to keep the corners intact, the algorithm uses a safe distance and makes sure the bridges are not built exactly at the corners. This helps to prevent undesired results after breaking the connections.
