Chain and datum dimensioning
WebYou can dimension to edges, vertices, and arcs (centers and minimum and maximum points). You can also dimension to midpoints when you add ordinate dimensions. Ordinate dimensions are automatically grouped to maintain alignment. When you drag any member of the group, all the members move together. WebLinear Dimensioning The accuracy of the final product is determined by the dimensions on the drawing. If all the dimensions originate from a common corner of the part, the object will be more accurate. This is referred to as Datum Dimensioning. Datums insure the tolerance or errors in manufacturing do not accumulate.
