## Parallel Line DevelopmentPresentation Transcript

•
• Step 1: Cylinder layout Draw the front elevation Using ‘d’ – diameter, ‘h’- height, ‘ a’- angle ‘A’ d= 3” h=3-1/2” a= 22-1/2” Establish a Center line to start
• Step 1: Cylinder layout Draw the front elevation Using ‘d’ – diameter, ‘h’- height, ‘ a’- angle ‘A’ d= 3” h=3-1/2” a= 22-1/2” Establish a Center line to start
• Draw a horizontal line perpendicular to the centre line, the length of a ‘d’ “3” long 3 .00 1.50
• Draw a vertical line parallel to the centre line, the length of h ‘3 ½ ‘ long 3 .00 3 .50
• 3 .00 3 .50 Using the protractor draw the angle at 22 ½” 22.5
• 3 .00 3 .50 22.5 Complete the elevation view by connecting the last line segment
• From Point A and using a compass draw an arc equal to the radius of the cylinder. A
• A 1 Draw an arc centered at point 1 using the same radius as before to intersect the semi circle.
• A 1 7 Witness the bisecting mark with a point and circle to identify.
• A 1 7 4 Label top intersection point 4 and construct and arc intersecting 2 points on the semi circle.
