Dimensioning вђ Basic Blueprint Reading This is done to avoid confusion with other lines. never draw leader lines entirely horizontal or vertical. quiz. directions: complete as indicated. dimension this drawing. the dimensions are 3” long, 2 1 8” wide, 1 5 8” high with a 45 angle ½” deep. the angle begins as the midpoint of the 3” long dimension. Beginner’s guide to blueprint reading. may 5, 2022 by brandon fowler. learning to read blueprints can be hard. that’s why we’ve broken down the process into bite size chunks. all of the basic components of an engineering drawing are detailed below with links throughout to give you more info on each subject. now playing.
Basic Blueprint Reading Chapter 6 Dimensioning Part 2 Youtube Since technical drawings are made of lines, it is logical that the first step in learning to “read” a drawing is to learn the meaning of each kind of line. generally, there are 11 basic types of lines. each kind of line has a definite form and “weight”. weight refers to line thickness or width. Determine the view. with 2d blueprints, there are three common perspectives: plan, elevation, and section. understanding which one of these is being employed is an important first step to reading any drawing. plan: a bird’s eye view of planned work. usually this is done on a horizontal plane at 30″ above the floor. The dimensions are 3” long, 2 1 8” wide, 1 5 8” high with a 45 angle ½” deep. the angle begins as the midpoint of the 3” long dimension. dimension this drawing. the base is ½” x 1 ½” square. the cylinder is 1” ∅. x 1 1 8”. long. the drilled through hole is ∅5 8”. quiz. Usually, the dimension line meets the extension line at right angles. there should be a gap of about 1 16″ where the extension line would meet the outline of the object, and the extension line should go beyond the outermost arrowhead approximately 1 8″. also, there should be not gaps where extension lines cross.
