The prompt
Generate a formal 2D mechanical engineering drawing for a miniature machined brass bolt. Render in a standard front cross-sectional view with dimension lines and extension lines using metric units (mm). Material: Brass. Total Axial Length: 10.8mm. Component Breakdowns from Head to Tip: 1. Head: Rounded, slotted head. Diameter = 3.9mm, Length = 1.55mm. Include a standard straight screwdriver slot centered on the face. 2. Shoulder/Collar: Smooth unthreaded cylinder immediately following the head. Diameter = 2.7mm, Length = 2.8mm. 3. Shank: Threaded section. Major Diameter = 1.75mm, Length = 6.45mm. Use standard schematic thread symbols (dashed hidden lines for minor diameter). Ensure all extension lines are clear, text labels are crisp, and dimensions sum perfectly to 10.8mm.
