Creates a named user parameter in the active Fusion 360 design. Use this before f360_set_parameter when a design does not already define the parameter. The value is numeric and unit defaults to mm.

Opens a new sketch on a construction plane in the active Fusion 360 design. MUST be called before any 2D drawing operation (draw_rectangle, draw_circle). XY = top view (most common for flat parts). XZ = front view. YZ = right-side view.

Draws a circle centered at the origin (0, 0) in the active sketch. f360_create_sketch must be called first. Use for cylindrical shafts, bosses, through-holes, or circular pads. Diameter in millimeters.

Draws a 2-point rectangle originating from (0, 0) in the active sketch. f360_create_sketch must be called first. Dimensions are in millimeters. For a 50×30 mm rectangle: width_mm=50, height_mm=30.

Exports the active Fusion 360 design as a STEP file (.step). STEP is the universal interchange format for CAD — use for supplier quotes, CNC machining, or importing into other CAD tools. Provide an absolute file path including filename and .step extension.

Exports the active Fusion 360 design as an STL file (.stl). STL is the standard format for 3D printing (FDM, SLA, SLS). mesh_refinement controls triangle density: 'low' = fast/coarse (prototypes), 'medium' = default, 'high' = fine (visual/SLA).

Extrudes the most recently created closed sketch profile into a 3D solid body. Call after f360_draw_rectangle or f360_draw_circle. Distance is in millimeters, positive = away from sketch plane. Creates a new body by default (not a cut).

Applies a constant-radius fillet to all edges of the most recently created solid body. Use to remove sharp edges for DFM (manufacturing) or aesthetic purposes. Radius in millimeters. This tool currently fillets every edge on the latest body.

Creates a hole on the top face of the most recently created solid body. Requires an existing solid body (call f360_extrude or f360_revolve first). Position is measured from the body origin in mm. hole_type: 'through' = passes all the way through the body; 'blind' = stops at depth_mm from the top face. Use for mounting holes and clearance holes. Threaded holes are not yet supported.

Creates multiple equally-spaced holes in a circular bolt-circle pattern on the top face of the most recently created solid body. Used for flanges, covers, and bolt-pattern connections. bolt_circle_dia_mm is the diameter of the circle on which hole centers sit. All holes are the same diameter and type.

Returns all user parameters in the active Fusion 360 design with their current values and units. Call this first to see what parameters are available before calling f360_set_parameter.

Checks if the Fusion 360 add-in TCP bridge is running and responsive. Returns connectivity status, version, and whether an active design is open. Use this tool first to diagnose bridge readiness before issuing modeling commands.

Revolves the most recently created sketch profile around a construction axis to create a solid body of revolution (shaft, flange, boss, cup, etc.). Call after f360_draw_rectangle or any closed sketch profile. axis: X = lathe-style rotation around X-axis (most common for symmetric parts), Y = rotation around Y-axis. angle_deg: 360 = full solid of revolution, less = partial arc. Sketch profile must be on one side of the chosen axis.

Updates a named user parameter in the active Fusion 360 design. The parameter must already exist (created manually in Fusion or via f360_create_parameter). Changing a parameter automatically rebuilds all features that reference it. Use this for batch variant generation: call once per variant, then export.

Hollows out the most recently created solid body by removing one face and creating a uniform wall thickness. Use for enclosures, housings, or injection-molded parts. Thickness in millimeters.
