I need a clean, professional 2-D CAD drawing of a simple wall sleeve used to form an opening through freshly poured concrete. I will supply a hand-sketch and a reference photo; the sketch shows all the features while the photo illustrates the overall look (it just happens to miss the tabs and end plate). Key geometry to capture: • Straight pipe section with a welded collar on one end • Four equally spaced tabs welded to the opposite end (90° apart) • Optional steel plate that can be shown as “add if required” on the collar side For now I only need a general view—no final dimensions or detailed material notes yet—so layout the sleeve at an indicative scale and leave space for me to add specific sizes later. Clarity and clean layer organisation are more important than precision at this stage. Please deliver an editable DWG (or DXF) along with a PDF for quick reference.
