This was a short term project, lasting approximately 2 days in hours. A school had commissioned my associate to model, as they wanted to invest in new foldaway seating for the students.
This was a task performed in AutoCAD and Inventor, using a combination of PDFs and photos for reference.
Technical drawings for the seating were imported into AutoCAD, traced, and then the drawing was imported into Inventor, where the outline could be extruded into the shape you see here.
The building itself was modeled from photos that my associate took of the internals, and using basic interior design knowledge and numbers, I was able to produce a relatively accurate representation of the building shape.
Each asset was modeled inside of an assembly file, rather than separate .ipt files, so as to insure visual accuracy.
