The prompt
Create a symmetric parametric mechanical truss frame. Units: mm Overall height: 280 Overall width: 50 Top head radius: 40 Straight lower section height: 200 Central vertical member width: 10 Number of truss sections: 4 Section height: 50 Place the vertical centerline at X=0. Create a rounded circular head of R40 at the top. Transition the head into two vertical outer side members. Create a 50 mm wide lower frame. Inside the frame, create a 10 mm wide central vertical member. Divide the lower 200 mm into four 50 mm sections. In each section create symmetric diamond/triangular diagonal bracing between the outer side members and the central member. Repeat the same bracing pattern in all four sections. Keep the entire design symmetric about X=0. Create a closed bottom member. Generate editable parametric B-Rep solid CAD geometry. Do not generate a mesh. Make the final model suitable for export to STEP and import into Siemens NX.
