Draft a plummer block (saddle bearing housing) in millimetres at full scale (1:1) as three orthographic views. Add no title or text notes. Use the supplied dimensioned diagrams diagram_01.png, diagram_01_detail01.png, diagram_01_detail02.png and diagram_01_detail03.png as the geometry reference.

Top view (upper left): the overall outline is 80 long by 40 deep, with R10 rounded corners on the front edge. There are two lugs, each 25 wide, one at each end. Draw two Ø8 holes, one in each lug, with centre lines. A 10-deep band along the rear edge is shown sectioned at the lugs, with hatching between the hidden-line projections of the holes.

Front view (lower left, aligned under the top view): 80 wide and 40 tall overall, on a 10-thick base. Cut a central half-round saddle of R20 into the top, with a 41.95 opening between the lug faces. Draw two side lugs with R8 rounded top corners, each pierced by a Ø8 hole. Show the holes' drill paths as hidden lines and the sectioned base portions under the lugs as hatched areas. Add a vertical centre line through the saddle.

Side view (lower right): 28.86 wide and 29 tall overall, with a 9-thick base step, and small fillets and internal edge lines as shown.

Dimensions: use native dimension objects on M-DIMS, 20 in total (11 linear, 5 radial, 4 diameter).

Linear: 80, 25, 25, 40 and 10 in the top view; 41.95, 40 and 10 in the front view; 28.86, 29 and 9 in the side view.
Radial: R10 ×2, R8 ×2 and R20.
Diameter: Ø8 ×4.

CAD standards: use exactly these layers.

M-OUTL: visible outlines, arcs and hole circles; ACI 7, Continuous, 0.5 mm.
M-HIDN: hidden edges; ACI 4, HIDDEN, 0.25 mm.
M-CNTR: centre lines and the four hole centre marks, which are placed as block references; ACI 1, CENTER, 0.18 mm.
M-HATC: section hatching; ACI 8, Continuous, 0.18 mm.
M-DIMS: dimensions; ACI 2, Continuous, 0.25 mm.

Fill the three sectioned regions with native ANSI31 hatch objects, not exploded lines. All objects must take colour, linetype and lineweight ByLayer. Leave nothing on layer 0.
