Engineering models are created by AutoCAD and final Architectural Model Created and presented by 3Ds Max. Sometime our students are feel interested to learn 3Ds Max skipping AutoCAD 3D. AutoCAD models are engineered and consultation related, where consultants can changing their mind after view a first look of AutoCAD 3D Model. AutoCAD 3D models are highly précised and accurate but 3Ds Max model are not similar to that. So, we suggest specially Civil and Mechanical engineering students not to avoid to learn AutoCAD 3D.
