| # Sketch and extrude the side disk | |
| Using only Autodesk Fusion's visible user interface, complete the CAD task below. Work in the root component and use millimetres. Do not use scripts, add-ins, the Fusion API, a terminal, or another CAD program. | |
| ## Required result | |
| Starting from the supplied body and existing construction plane Plane1, create a fully constrained sketch on Plane1. Draw exactly one Ø85 mm circle centered at the midpoint of the lower longitudinal edge of the original 100 mm housing section: global X = 50 mm, Y = −45 mm, Z = 37.5 mm. Finish the sketch, then extrude the circular profile symmetrically about Plane1 by 10.5 mm on each side, for 21 mm total thickness, with 0° taper and Join. The disk must span global Z = 27 mm to Z = 48 mm and remain part of the single body. Stop with exactly one new sketch and one new extrusion feature. | |
| ## Completion requirements | |
| Finish the sketch and feature operations, leave the completed design open in Fusion, and do not add geometry or features not requested above. | |
| Do not use Save or Save As. Do not open or import any external CAD file, including another task seed or answer. The environment exports the open design automatically; use the finish action when the task is complete. | |
