Create a professional 2D AutoCAD engineering drawing of a water reservoir for a civil engineering graduation project. Generate a detailed cross-section (Section A-A) of a rectangular reservoir measuring 4.0 m long, 3.0 m wide, and 1.10 m deep, including 1.00 m water depth and 0.10 m freeboard. Show reinforced concrete edge beam (200 × 200 mm), 100 mm sand bedding, 1.5 mm HDPE liner, compacted soil, groundwater level, PVC inlet pipe Ø50 mm, overflow pipe Ø75 mm, outlet pipe Ø50 mm with ball valve, and a water level gauge. Include professional ISO dimensioning, elevation levels, annotations, hatch patterns for concrete, soil, sand, water and HDPE liner, centerlines, hidden lines where required, correct line weights, layers, engineering symbols, and a title block. Use a clean black-and-white AutoCAD plotting style with technical drafting standards. The drawing must look exactly like a professional AutoCAD PDF exported by a civil engineering company. Output both DWG and high-resolution PDF.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
