These three drawings are Mechanical hand drawings in orthographic projection with dimensions.Orthographic projectino allows us to see the top,front,and right side view of an object,demensioning gives us the dimensions that we need to be able to draw it.
This was a classroom drawing that we had to perform.This was the biggest drawing we have ever constructed,and was a very teadious process to perform correctly.We did this drawing to push our Mechanical drawings to the max with all the desks,blackboards,cabinets and other what nots throughout the drawing.
The final Mechanical drawing we had to perform was an Isometric Exploded.This drawing was rather difficult for me,because we had to draw the object in 3D to get the full isometric view.
