DESCRIPTION

. " ". . "-3D" 2D 3D . - . . This coursework was completed in my third year at the MSTU n.a. Bauman on discipline Bases of designing devices. Anatoly designed a linear motion mechanism based on the proposed scheme and requirements. He also prepared an explanatory note on the design of this mechanism. The project was completed in a CAD system "Kompas-3D" in 2D and 3D design forms. Anatoly received an excellent mark.
