This technical drawing depicts a detailed profile of a guitar neck with precise dimensional specifications in millimeters. This blueprint features multiple radius measurements including R35.98, R21.4, R18.43, and R10.58 that define the ergonomic contours of the neck. The overall length spans approximately 124.22mm with a width profile varying between 54.3mm and 72.73mm at different measurement points. Notable are the carefully designed transitions between the front and back profiles with several smaller radii (R3.14, R3.44, R5.25) creating smooth edge transitions. The drawing employs numerous arc entities to accurately represent the complex ergonomic curves, which allow for comfortable hand positioning and playability. The thickness varies from approximately 17.91mm to 23.83mm, reflecting a modern neck profile that balances comfort and structural integrity.
