Design of metal structures in Autodesk Inventor

I designed a durable and practical metal staircase made of steel tubes and coated with electrostatic powder paint. The structure consists of longitudinal and transverse elements made from 40x25x2 mm tube, while the steps are made from 30x20x3 mm tube.
Along with the 3D model, 2D technical documentation for external production was provided. The staircase was made strictly according to the client's dimensions and requirements and was successfully delivered on time.
Results for the client:
3D model developed according to the client's specifications.
2D drawing with dimensions for production.

Assembly and installation drawings.
Complete list of materials (BOM).
Installation guide and technical recommendations for assembly and maintenance.
Complete documentation package provided in digital format (PDF/DWG/STEP).
