“Make a lever-operated ball valve in the 30° open position as 6 separate solids (body, ball, 2 seat rings, stem, handle). Coordinate system: flow axis = X axis, ball center = origin, stem axis = Z axis. Direction d = (cos30°, sin30°, 0) = (0.86603, 0.5, 0) is the direction of the ball bore and the handle, and e = (-0.5, 0.86603, 0) is the horizontal direction perpendicular to it. (1) Body (one solid): block X=-40~40, Y=-30~30, Z=-30~30. A Ø20 flow hole runs through the full length in the X direction, with Ø26 pipe counterbores at both ends (X=30~40, X=-40~-30). Internal cavity: Ø48 cylinder on the X axis, X=-22~22 (enclosed space). A Ø12 stem hole on the Z axis runs from the cavity to the top face Z=30. (2) Ball: Ø40 sphere (centered at the origin). A Ø20 ball bore runs through along an axis in direction d. Stem tang slot on the top: long in direction d, width 6 (±3) in direction e, from Z=15 to the sphere surface (through the full length in direction d). (3) 2 seat rings: each an annular cylinder on the X axis, outer diameter Ø48, inner diameter Ø20, one at X=15~22 and the other at X=-22~-15. The side facing the ball is cut to the ball's spherical surface (Ø40) so that it seats against the ball. (4) Stem (one solid): tang = cuboid with length 16 (±8) in direction d, thickness 6 (±3) in direction e, Z=15~21 (inside the ball's slot). Ø12 shaft at Z=21~45. Top-end 10×10 square (sides parallel to directions d and e) at Z=45~55. (5) Handle (one solid): plate at Z=46~52. Measured from the stem axis, it runs from -20 to +100 in direction d, width 20 (±10) in direction e, with a 10×10 square hole that the stem square fits into (sides parallel to d and e). That is, the handle points in the same 30° direction as the ball bore.”

“Model a swivel caster as seven separate solids: top plate, thrust washer, kingpin bolt, nut, fork, wheel, axle. Frame: the kingpin (swivel) axis is the Z axis; the floor is Z=0 and the wheel touches it. Top plate: X=-40..40, Y=-40..40, Z=100..105 (edges parallel to X and Y), Ø12 hole on the Z axis and four Ø9 holes at (±30, ±30), all through along Z. Thrust washer: Ø40, bore Ø12, Z=92..100, on the Z axis. Kingpin bolt: shank Ø12 from Z=78 to Z=105 on the Z axis, head Ø20 from Z=105 to Z=110. Nut: Ø20 cylinder, bore Ø12, Z=78..84. Fork, one solid, described in a fork frame whose origin is on the Z axis: its x axis is the horizontal direction (cos35°, sin35°, 0), its y axis is (-sin35°, cos35°, 0), z = world Z. Crown plate: x=-42..15, y=-23..23, Z=84..92, with a Ø12 hole on the Z axis. Two legs, 5 thick, at y=18..23 and y=-23..-18; each leg (in the x-Z plane) is the rectangle x=-42..-18, Z=37.5..84 united with a disc R12 centred on the axle point (x=-30, Z=37.5), and has a Ø10 axle hole there. So the axle sits 30 behind the kingpin toward the 215° direction, at world (X, Y) = (-24.575, -17.207), Z=37.5. Wheel: axis along the fork y axis through the axle point. Tyre Ø75 over y=-15..15, hub Ø30 over y=-18..18 (the hub faces touch the legs), bore Ø10. Axle: Ø10 along the fork y axis from y=-26 to y=26 through the legs and wheel, with Ø16 heads over y=23..26 and y=-26..-23 bearing on the outer faces of the legs.”

“Model a meshing spur gear pair as two separate solids. Frame: both gear axes are parallel to the X axis. The pinion axis passes through Y=20, Z=-10; the wheel axis passes through Y=99.674, Z=36, so the line of centres runs 30° from +Y toward +Z (centre distance 92). Angular positions about each axis are measured in the YZ plane from +Y toward +Z. Tooth form for both: involute, module 4, pressure angle 20°, no profile shift, addendum 1.0m, root diameter = pitch diameter - 2.5m, root fillets free. Backlash: circular tooth thickness on the pitch circle = pi*m/2 - 0.15 = 6.133, symmetric about the tooth centre line. Both toothed widths span X=0..30. Pinion (a gear shaft, one solid): 17 teeth, pitch Ø68, outside Ø76, root Ø58. Shaft Ø30 from X=-50 to X=0 and from X=30 to X=75. The X=30..75 end has a square-ended keyway 8 wide from X=48 to X=75 on the 90° side (+Z side of the shaft), floor 11 from the pinion axis. Phase: the pinion has a tooth SPACE centred on the 30° direction (toward the wheel). Wheel: 29 teeth, pitch Ø116, outside Ø124, root Ø106. Both side faces are recessed: an annular pocket from Ø56 out to Ø88, 9 deep, is cut into the X=0 face (X=0..9) and into the X=30 face (X=21..30), leaving a web X=9..21. Hub Ø56 from X=-10 to X=30 (it sticks out 10 on the -X side). Ø32 bore through X=-10..30 with a 10 wide keyway on the 90° side over the full length, keyway floor 20.3 from the wheel axis. A radial Ø6.8 set-screw hole at X=-5 runs from the hub surface into the bore on the 0° side (+Y side). Phase: the wheel has a TOOTH centred on the 210° direction from its own axis (toward the pinion), which sits in the pinion's tooth space.”

“Make a bench vise in the assembled state as 6 separate solids (body, movable jaw, fixed jaw plate, movable jaw plate, screw, handle). Coordinate system: the jaw moves in the X direction, and the screw axis is the line (Y=0, Z=45) parallel to the X axis. Bottom face Z=0. (1) Body (one solid): base plate X=-60~100, Y=-40~40, Z=0~12. Fixed jaw block X=-60~-40, Y=-40~40, Z=12~60. Guide bar X=-40~90, Y=-15~15, Z=12~30. End plate X=90~100, Y=-25~25, Z=12~60, with a Ø14 hole through in the X direction on the screw axis. (2) Fixed jaw plate: X=-40~-36, Y=-38~38, Z=40~60 (attached to the +X face of the fixed jaw block). (3) Movable jaw (one solid): block X=5.5~35.5, Y=-40~40, Z=12~60 with a channel Y=-15~15, Z=12~30 that wraps around the guide removed over the full length in X (the channel top face contacts the guide top face Z=30, and its side faces contact the guide side faces). A Ø14 blind hole on the screw axis from the +X face (X=35.5), depth 12 (X=23.5~35.5, flat bottom). (4) Movable jaw plate: X=1.5~5.5, Y=-38~38, Z=40~60 (attached to the -X face of the movable jaw). Therefore the opening between the two jaw plates (X=-36~1.5) is 37.5. (5) Screw (one solid, a cylinder with the thread omitted): Ø14 at X=23.5~110 (its end touches the bottom of the movable jaw's blind hole and it passes through the end plate hole), head Ø24 at X=110~122. A Ø8 hole through the head in the Z direction at X=116. (6) Handle (one solid): Ø8 rod passing through the head hole in the Z direction, axis (X=116, Y=0), Z=0~90. Ø14 knobs at both ends: Z=-6~0 and Z=90~96.”

“Make a twisted blade lofted through 3 NACA symmetric airfoil sections, together with a root block, as a single solid. Coordinate system: blade span direction = +Z, twist axis = Z axis (the 1/4-chord point of each section lies on the Z axis). Section definition (local coordinates x, y within the section plane Z=z): the chord line lies on the local x axis, leading edge (LE) at x = -c/4, trailing edge (TE) at x = 3c/4. The thickness distribution follows the NACA 4-digit symmetric formula y = ±5·t·c·(0.2969·√ξ - 0.1260·ξ - 0.3516·ξ² + 0.2843·ξ³ - 0.1036·ξ⁴), ξ = (x + c/4)/c (0~1), and the trailing edge closes to a sharp point. The local coordinates are rotated counterclockwise by the twist angle, as seen looking down from +Z, and then placed in the world (local x axis = (cosθ, sinθ, 0)). - Section 1: Z=0, chord c=60, thickness ratio t=0.15 (NACA 0015), twist θ=0°. - Section 2: Z=60, c=48, t=0.12 (NACA 0012), θ=15°. - Section 3: Z=120, c=36, t=0.10 (NACA 0010), θ=30°. Blade = smooth loft passing through the three sections in order (Z=0~120, flat ends). Root block: cuboid X=-20~50, Y=-14~14, Z=-20~0 (the blade root face attaches to its top face), with a Ø10 hole through in the Y direction, axis at (X=15, Z=-10).”
