Dimension Practices

Linear Dimensions Linear dimensions are divided into two categories: Size Dimensions Location Dimensions These two categories will be used in this PowerPoint and the rest of the lesson.

Size Dimensions Size dimensions describe the size of each geometric feature. With respect to linear dimensions, size dimensions are sometimes referred to as overall dimensions, and will tell the viewer the overall width, height, and depth of an object.

Size Dimensions

Location Dimensions Location dimensions show the location of each geometric feature within an object or view. Location dimensions tell the viewer where edges occur inside an object view.

Location Dimensions Linear Dimensions Introduction to Engineering DesignTM Unit 1 – Lesson 1.3 – Measurement and Statistics Location Dimensions The students should notice the location of the dimensions and how the largest are on the top or outside and they get gradually smaller as you get closer to the object.
