The document contains instructions forsection view exercises and a tutorial with The course Engineering Drawing is extremely important as it is the language of engineers, technicians, designers and sanitarians. The basic idea of Descriptive Geometry is to use two projection planes, a horizontal one, de ̄ned by the axes x and y; and a frontal one de ̄ned by the axes x and z: We note the horizontal plane by Development of a right circular cylinder. This figure is a 3D representation of the part after it is sectioned. The direction of the arrow can also be thought of as pointing toward the half of the object being kept. The corners of the section view are numbered so that they can be compared with the orthographic Findi.) type of fit and (ii) tolerances of amm diameter shaft rotating at a normal speedFix the limits of tolerance and allowance for amm diameter shaft and hole pair ENGINEERING DRAWING PRACTICE MANUAL I Table Dimensioning: Drawing of a component, in addition to providing complete shape description, must also furnish Information regarding the size description. This handbook is devoted to provide general sectional view to complete the drawing. Half of the object is removed to reveal the interior features of the part. These are provided through the distances betwee n the Surfaces, location of holes, nature of surface finish, type of material, etc The direction the cutting plane arrows points represents the direction of sight for producing a section view. The second shows up well on complicated drawings. At each end of this line, construct vertical lines equal in length to the height of the cylinder. Draw the arrows at right angles to the line Seasoned engineers can interpret orthogonal drawings without needing an isometric drawing, but this takes a bit of practice ASME specifi es two forms for cutting-plane lines, as shown in Figure The fi rst form is more commonly used. The document discusses sectional view drawings, Project the section view exerciseIn first angle orthographic projection, complete a sectional: Front elevation on the cutting plane Z-Z. If you have difficulty placing the Project the section view exerciseIn first angle orthographic projection, complete a sectional: End elevation on the cutting plane X-X. If you have difficulty placing the Section Orthographic Projection explained with following timestamp: – Engineering Drawing lecture series – Significance of sectional orthographic p s a point P and a system of cartesian coordinates. Copy View to Be Cross Sectioned Start the process by copying the front view (third angle projection) of the object. The line of sight for the section view is perpendicular This cross-sectional view (section A-A, figure), one that is orthogonal to the viewing direction, shows the relationships of lengths and diameters better. These drawings are easier to make than isometric drawings. This section view more clearly shows the interior features of the part. StepIn the front view, draw the stretch-out line aligned with the base of the cylinder and equal in length to the circumference of the base circle. Step 2A section view is created by passing an imaginary cutting plane vertically through the center of the part.

At each end of the line, draw a short line with an arrow to show the direction for looking at the section.
