: It features a new "Fast" dynamic shape fill mode that can be up to 100 times faster than the "Smooth" mode found in older releases. Interactive 3D Engine

One of the most valuable uses of the viewer is to of a board that you only have in .brd format. The viewer preserves the original stack‑up, netlist, and rule definitions. By carefully inspecting the layer stack and differential‑pair definitions, you can deduce the target impedance, the intended routing strategy, and even the signal‑integrity philosophy of the original designer.
