The prompt
[SYSTEM COMMAND: GENERATE 2D PROFILE DXF] [UNITS: INCHES] [ORIGIN (0,0): INTERSECTION OF RECEIVER FRONT FACE AND BORE CENTERLINE] --- MASTER BOUNDARY PROFILE POINTS --- 1. BORE CENTERLINE: - Infinite Horizontal Construction Axis along Y = 0. 2. RECEIVER BLOCK (RECTANGULAR ENVELOPE): - X-Interval: From X = -11.125 to X = 0.000 - Y-Interval: From Y = -1.875 to Y = +1.250 - Total Box Dimensions: Length = 11.125, Height = 3.125 - Align front-right vertical edge exactly to X = 0. 3. MAIN BARREL STEP-DOWNS (COAXIAL CYLINDERS ALONG Y = 0): - Chamber Section: From X = 0.000 to X = 4.000 | Diameter = 1.250 (Y = +0.625 to Y = -0.625) - Mid-Barrel Section: From X = 4.000 to X = 15.000 | Diameter = 0.9375 (Y = +0.4688 to Y = -0.4688) - Muzzle Section: From X = 15.000 to X = 24.000 | Diameter = 0.6875 (Y = +0.3438 to Y = -0.3438) - Total Barrel Length: 24.000 inches extending along positive X-axis. 4. LOWER GAS TUBE CYLINDER: - Horizontal Centerline parallel to Bore Axis at Y = -1.125 - Outer Tube Diameter: 0.750 (Limits from Y = -0.750 to Y = -1.500) - X-Interval: From X = 0.000 to X = 19.500 5. WOODEN FOREARM GRIP (LOWER PROFILE): - X-Interval: From X = 0.000 to X = 10.500 - Max Depth Point: Y = -2.125 at X = 0.000, tapering gently upward to meet the gas tube profile at X = 10.500. 6. REMOVABLE BOX MAGAZINE PROFILE: - Top Interface Anchor: X = -3.500 at bottom of receiver (Y = -1.875) - Magazine Width (Fore-to-Aft): 3.1875 - Projection Depth: Extending downward to Y = -6.375 - Angular Tilt: Rotate entire magazine profile exactly 6.0 degrees clockwise relative to absolute vertical. 7. REAR BUTTSTOCK PROFILE: - X-Interval: From X = -11.125 (Receiver back face) to X = -22.625 (Buttplate surface) - Total Longitudinal Length: 11.500 - Upper Comb Drop Line: Linear path from Point (-11.125, +1.250) sloping down at 14.0 degrees to Point (-22.625, -1.500) - Lower Belly Line: Linear path from Point (-11.125, -1.875) sloping down at 9.0 degrees to Point (-22.625, -3.375) - Rear Buttplate Height: Vertical line bounding the rear envelope from Y = -1.500 to Y = -3.375. --- GEOMETRIC CONSTRAINTS --- - Apply H (Horizontal) constraint to all barrel segments and the receiver top edge. - Apply V (Vertical) constraint to the receiver front face (X=0) and receiver back face (X=-11.125). - Apply Tangent arcs at all step-down intersection corners to avoid sharp non-manifold edges. - Ensure all closed sketch loops are cleanly isolated for extrusion selection.
