The prompt
Create a detailed 3D assembly model of a bolted flange pipe connection. All dimensions are in millimeters. Use the following exact specifications: 1. Bolt (M16): - Shank diameter (d): 16 mm, length of threaded part = 60 mm (total bolt length l = 60 mm). - Hex head: width across flats (e) = 32 mm, height (k) = 11.2 mm. - Chamfer on head: 2x45°. 2. Flanges (two identical, steel): - Outer diameter (D): 145 mm. - Thickness (b1 = b2): 20 mm each. - Raised face (D2): diameter 86 mm, height 5 mm. - Bolt hole diameter (d0): 18 mm. - Number of bolt holes (n): 4, arranged on a bolt circle diameter D1 = 110 mm. 3. Gasket (between flanges): - Outer diameter (Dpr): 86 mm. - Inner diameter (dpr): 45 mm. - Thickness (Spr): 2 mm. 4. Washer: - Outer diameter (dsh): 35.2 mm. - Thickness (Ssh): 2.4 mm. 5. Nut (M16): - Width across flats (S): 27.2 mm. - Height (m): 12.8 mm. - Chamfer: 2x45°. Assembly order (left to right): Bolt head -> Flange 1 -> Gasket -> Flange 2 -> Washer -> Nut -> Bolt end protrusion (a = 4.8 mm). Ensure the bolt passes through the center hole and the nut is fully seated on the washer.
