Here are two videos that nicely illustrate how traditional timber framing (and even panelized light-framing) has evolved from the chisel to the CNC cutter and the nailing gantry. The first one is a more hands-on approach where power-tools are used to do individual cuts. The second one is a fully CNC-based process, where every single member is designed in the computer (using the Cadwork software in this case) and then sent to a milling or nailing machine for fabrication.

Level 2: Computer design and CNC cutting
