The prompt
Generate a 2D CAD engineering layout for a matching inner and outer pair of 5-point aggressive chainsaw felling dogs tailored for a Stihl MS461 chassis. Material thickness is exactly 3.175mm (1/8 inch) flat stock alloy steel. The overall vertical height is 165mm, extending 35mm below the standard bar line to serve as a deep-bark pivot. Implement a 5-point geometric spike configuration where the middle (center) spike is elongated by 12mm relative to the other spikes to align perfectly with the chain kerf and act as the primary articulation pivot. All spikes must feature sharp, forward-raked 20-degree triangular teeth with deep, radius-cleared gullets to prevent wood packing. The inner plate must feature a standardized Stihl 2-bolt crankcase mounting pattern: two 5.5mm diameter mounting holes positioned horizontally aligned with a center-to-center distance of exactly 51.5mm, including a 10mm deep radius clearance cutout to clear the chain catcher and bar-pad glide plates. The outer plate must reflect the exact same footprint but mirror the structural profile to mount flat against the sprocket/clutch cover assembly.
