1. Greenfaulds High School Cylinder Development

2. Development of Cylinder (1) Draw a base line for the Development. If possible make this line level with the base line of the Elevation and End Elevation. 1 12 11 10 2 Step off the distance from each of the points on the Plan onto the Development base line. Draw a line to indicate where the first generator of the Development will go.

3. Development of Cylinder (2) Draw generators through each of the points found. 1 12 11 10 9 8 7 6 5 4 3 2 9 10 8 11 7 12 6 1 5 2 4 3 6 7 5 8 4 9 3 10 2 11 1 12 Number each of the generators. Choose carefully where to cut the Cylinder. It is normal to choose to cut the Cylinder on the shortest generator. 9 8 7 65 4 3 21121110 3

4. Development of Cylinder (3) Transfer each of the points from the generators on the End Elevation onto the correct generators on the Development. 9 8 7 65 4 3 21121110 Indicate each of the points with a small dot. 3

5. Development of Cylinder (4) Draw a smooth curve through each of the points found on the Development. Darken the outlines of the rest of the Development 9 8 7 65 4 3 21121110 3
