Dimensioning

Size Dimensioning is something that shows how big the object itself really is. While on the other hand location dimensions show where something should be placed exactly.

Chain Dimensioning goes from one point to an end point then from that end point to another end point and continues from there. Datum Dimensioning is when you dimension out from the same start point to a different end point. I feel like chain dimensioning will create less deviation because it shows explicitly how much the part should be.

Written Description is much harder to understand then a dimensioned drawing. However they both still explain the process to which to create an object. The dimesioned drawing is much easier because it shows how the object should look
