Sketch and extrude the lower support
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 Ø85 mm side disk, create a fully constrained sketch on its negative-Z planar face at global Z = 27 mm. Use the existing straight lower housing edge to close the top of one support profile. Place two vertical sketch lines at global X = 30 mm and X = 70 mm, start both on the housing edge at Y = −45 mm, and extend each 30 mm toward negative Y to Y = −75 mm. Connect their lower endpoints with a minor R30 mm arc bulging toward negative Y. Finish the sketch, then extrude that one closed profile 35 mm from Z = 27 mm toward negative Z, ending at Z = −8 mm, with 0° taper and Join. Stop with exactly one new sketch, one new extrusion feature, and one solid body.
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.
