The two red dimensions added are the right dimensions since the one in the book was wrong. Three sheet of paper will need to be submitted. One assembly drawing with part list, and two detail drawings for the nonstandard parts (linkage and support block). It is not required to draw the thread and head of the screw and nut detailly (standard parts). Drawing sheet must follow the engineering standard as working drawing. Three sheets can be placed seperate .dwg files.
