2. Auxiliary Drawing Upon completion of this assignment, you will be able to accurately and neatly construct an auxiliary drawing of a cylinder surface that is a true size and true shape (such as for a rocket). Copyright © Texas Education Agency, 2012. All rights reserved.

3. 3

4. 4 1. Lay out cylinder 2 x.5. 1A. CAD construct cylinder, cylinder command or extrude circle. Copyright © Texas Education Agency, 2012. All rights reserved.

5. 5 2. Construct a 45 degree angle from top left to right. 2A. CAD - slice a 456 Degree 50 or subtract area angle 2.5 x. 5. Copyright © Texas Education Agency, 2012. All rights reserved.

6. 6 3. Construct a three view drawing of the 45 degree angle. 3A. CAD- copy and past the 45 degree cylinder in to front view top view & right side position. Copyright © Texas Education Agency, 2012. All rights reserved.

7. 7 4. Place in cutting plane line in top & front view. 4A. CAD - same Note (line type cutting plane line ) P. Copyright © Texas Education Agency, 2012. All rights reserved.

8. 8 5. From reference plane line RP# 2, construct a parallel line 7 inches from RP# 2. Draw in extension lines 90 Degrees from top to bottom of RP# 2. Call parallel line from RP#2 (RP# 3). 5A. CAD - Same. Copyright © Texas Education Agency, 2012. All rights reserved.

9. 9 6. Divide up top view 8 times with triangle and project the lines through and to auxiliary view RP# 3. Label points. 6A. CAD – Same Label all points. Copyright © Texas Education Agency, 2012. All rights reserved.

10. 10 7. Divide up top view 8 times with triangle and t-square; then label the lines 1-8. Extend lines through and to auxiliary view RP# 3. Label points as shown in view RP# 3 – one in pencil, one in CAD. Measure from RPL (180) to point 2, then point 8 (should be same). Carry down and to auxiliary PR#3. Same in cad with line commands. This is a line command and Text. Carry all dimensions all the way around and back to finish. You are finding true width on to true height making true size true shape object out of RP#3 (as shown). 7. A. CAD the same. Label all points – one in pencil, one in CAD. That is where we are getting doubles. Copyright © Texas Education Agency, 2012. All rights reserved.

11. 11 8. Connect the dots as shown until you get a perfect oval, or match the dots. Copyright © Texas Education Agency, 2012. All rights reserved.

12. 12 9. Connect dots AS SHOWN. 9 A. CAD- connect dots and union, or align front view solid into oval or rotate front view into area to finish drawing as shown. Copyright © Texas Education Agency, 2012. All rights reserved.
