Activity 7.1

Size dimension is different from location dimension because size dimension describes the size of each geometric feature while location dimension describes a point on a geometric figure. Datum dimension is where a single point is used as a reference point for all other figures while chain dimension is connecting points to make a figure. Chain dimension usually results in smaller parts. Dimension drawings and a written description are similar because they both show the general idea, however they are different because dimension drawings show specific detail and a picture in front of you while the written description only gives you an idea.
