Task

Build a complete 3D model and a two-sheet drawing of a steel access staircase with two landings, handrails and grating steps. Work in millimetres and follow the supplied dimensioned diagrams diagram_01.png, diagram_01_detail01.png, diagram_01_detail02.png, diagram_01_sheet2.png, diagram_01_detail03.png and diagram_01_detail04.png.

Structure layout:

Lower landing: 1600 x 2250 mm in plan. Its deck sits 3360 mm above ground (1680 + 1680), with an intermediate bracing level. It stands on four columns.
Upper landing: 700 x 1100 mm in plan. Its deck sits 7000 mm above ground on a four-column tower braced at 2350, 2350 and 2300 mm intervals. The tower columns are 700 mm apart in the front view.
Front-view spacing: 1600 mm between the lower-landing columns and 4000 mm from the lower landing to the tower, for an overall length of 7100 mm.
Lower flight: 900 mm clear width (1000 mm overall). It runs from the ground to the lower landing with a 5100 mm sloped length and a 3800 mm horizontal projection.
Upper flight: 1100 mm wide, with a 5250 mm sloped length. It rises from the lower landing to the upper landing.

Detail parts:

Every column ends in an MS stub base: a column stub welded to a base plate, with bolt holes (Detail A).
Each step is a grating tread on L-angle supports. Steps are spaced 310 mm along the stringer and 200 mm apart vertically, with a 38 mm grating depth.
Handrails with posts, mid-rails and toe plates run along both flights and around the landings. The landing guardrails are 1200 mm high.

Model each member type as its own part. Use names such as GRETING, STEP/STEPS, L_ANGLE, MS_STUB, TOE, OMEGA and SQ for the grating, steps, angles, base stubs, toe plates, handrail/omega sections and square columns. Assemble all parts in one product.

Produce an A3 drawing with two sheets:

Sheet 1: front, right and top views with the overall and level dimensions listed above. Add Detail A (MS stub), an isometric view of a single step (L angle, L angle for support) and an isometric of the step details with the 310, 200 and 38 mm dimensions. Label all views.
Sheet 2: an isometric view of the whole staircase.

Use the title "STEEL ACCESS STAIRCASE WITH TWO LANDINGS, HANDRAILS AND GRATING STEPS".
