Build the double end flange with raised inset
Complete the CAD task below in Autodesk Fusion. You may build the geometry with the normal Fusion user interface, or by writing Fusion 360 Python API (adsk) code and executing it in Fusion's Text Commands palette (open it from the View menu if hidden, and make sure the input mode toggle at the bottom right of the palette is set to Py, not Txt), or any combination of both. Work in the root component and use millimetres. Do not use a terminal outside Fusion and do not open or import any external CAD file.
This is a multi-stage build with 3 stages completed in one episode. Work strictly in the document that is already open: do not create a new document and do not open or import any file—work done in a different document scores zero. Complete the stages in order; each stage builds on the result of the previous one. Do not add solid features beyond those specified.
Required result
Stage 1 of 3
Starting from the supplied 100 mm keyed shaft, create a fully constrained sketch on its exposed terminal face. Draw exactly one Ø62 mm circle concentric with the main X axis and coincident with the sketch origin. Finish the sketch. Select both face regions inside the Ø62 mm boundary—the keyed central region and its surrounding region—and extrude them together 10 mm outward in the positive X direction, one-sided, with 0° taper and Join. The result must be one complete Ø62 mm circular flange, one new sketch, one new extrusion feature, and one solid body.
Stage 2 of 3
On the Ø62 mm flange from the previous stage, create a new fully constrained sketch on the flange's exposed terminal face. Offset the Ø62 mm circular perimeter inward by 1 mm using a −1 mm sketch offset, producing exactly one centered Ø60 mm profile. Finish the sketch, then extrude the central Ø60 mm disk—not the surrounding annulus—1 mm outward in the positive X direction with a one-sided 0° Join extrusion. The result must be a solid raised Ø60 mm disk with no enclosed cavity, exactly one new sketch, one new extrusion feature, and one solid body.
Stage 3 of 3
On the raised Ø60 mm end face from the previous stage, create a fully constrained sketch on that face. Draw exactly one Ø62 mm circle concentric with the main X axis and coincident with the sketch origin. Finish the sketch. Select both regions inside the Ø62 mm boundary—the central Ø60 mm face and the surrounding Ø60-to-Ø62 mm annulus—and extrude them together 10 mm outward in the positive X direction, one-sided, with 0° taper and Join. The result must be a complete Ø62 mm circular end flange, exactly one new sketch, one new extrusion feature, and one solid body.
End state across all stages: exactly 3 new sketches, 3 new extrusion or cut features, 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.
