ORTHOGRAPHIC READING Analysis by Solids
BASIC IDEA Objects are decomposed into solid geometric primitives. Some of familiar solid objects Rectangular prism Cylinder Negative cylinder (Hole)
BASIC IDEA Objects are decomposed into solid geometric primitives. Some of familiar solid objects Cone Pyramid Sphere
READING STEPS 1. Orient yourself with the views given. (Choose the viewing direction. ) 2. Read the individual surfaces that appeared in each view and related to each other. 3. Create a proper solid geometric primitive from each reading. 4. Assembly all of solid geometric primitive according to orthographic views.
EXAMPLE A Given Composition Rectangular prism Hole Front View
EXAMPLE B Given Composition Rectangular prism Cylinder Front View
EXAMPLE C Given Composition Cylinder with a blind hole. L-shaped with round end Hole
EXAMPLE D Given Composition Wedge
EXAMPLE D Given Composition Wedge L-shaped block
ORTHOGRAPHIC READING Analysis by Surfaces
READING STEPS 1. Orient yourself with the views given. 2. Read the individual set of lines or surface that appeared in each view and related to each other. An understanding in orthographic projection, i. e. meaning of lines and surfaces are almost important.
READING STEPS 3. Mentally create and sketch a form of the surface that produce the same orthographic views as those at the beginning. 4. Repeat steps 2 and 3 until all surfaces are read. During this repeating process, the details of an object are added up until its completed shape is obtained.
GUIDANCE 1 Adjacent areas that are not in the same plane must be separated by lines. Different plane Same plane Line exists Edge view
EXAMPLE Top view B All surfaces A, B and A C are not in the same plane. C Some of possible objects’ shape. A A A C B B C
GUIDANCE 2 Areas that show a similar shape in more than one view is the same surface. Similar shape
