  "task": "Draft the front elevation of a multi-storey commercial tower with podium",
  "domain": "CAD",
  "application": "AutoCAD",
  "description": "Draft, in 2D at full size with drawing units set to inches, a single front elevation of a multi-storey commercial building, as shown on the supplied dimensioned diagram diagram_01.png. The overall extent is 1710.08 wide by 1813.9 high.\n\nHorizontal divisions along the base, left to right, are 448.23, 242.87, 700.8 and 318.18. Vertical divisions, bottom to top, are 451.9 (podium), then 288, 294, 258 and 264 (tower shaft), then 258 (rooftop crown).\n\nComposition, bottom to top:\n- A low podium on a continuous ground/plinth line.\n  - At left are two stepped, horizontally banded blocks with sloping parapets.\n  - Next is a fully glazed, gridded curtain-wall volume containing a double entrance door.\n  - The centre has a splayed wall with a second, larger double door.\n  - At right is a glazed block with curtain-wall grids.\n- A tower shaft above the podium:\n  - A canted (inclined) left frame enclosing six cantilevered horizontal balcony/slab bands, each with a small glazed corner panel at its left end.\n  - Six short floor projections down the left edge.\n  - A vertical brick-clad pier and a brick-clad top band.\n  - A tall vertical feature column at the right, with a square-box infill pattern.\n- A recessed rooftop crown: two gridded parapet tiers, then a smaller gridded plant enclosure, topped by a sloped mechanical penthouse.\n- A rectangular border frame around the whole drawing.\n\nNo dimensions or text are required in the drawing.\n\nCAD standards:\n- Create the following layers:\n  - A-ELEV (ACI 7, Continuous, 0.35 mm): all building outline, massing, banding, roof and border linework, using lines and polylines.\n  - A-GLAZ (ACI 4, Continuous, 0.18 mm): all curtain-wall and window mullion/transom grid lines.\n  - A-DOOR (ACI 3, Continuous, 0.25 mm): the entrance door leaves and frames.\n  - A-ELEV-PATT (ACI 8, Continuous, 0.13 mm): material hatches.\n- Use native hatches only:\n  - BOX pattern for the right feature column (3 hatch objects).\n  - AR-BRSTD for the brick pier and brick top band (2 hatch objects).\n- All objects take colour, linetype and lineweight ByLayer.\n- Nothing is drawn on layer 0.",
