1 Cylinders

2 Cut Cylinder The views show the Front Elevation and part Plan of a cut Cylinder

3 Finding position of End Elevation Draw the outline of the End Elevation. The dimensions for the End Elevation should be projected from the Elevation and Plan.

4 Finding Generators on Plan Divide the Plan into 12 areas by using 30 o and 60 o lines Number each of the points found

5 Drawing Generators onto Elevation Project each of the points from the Plan onto the Elevation base Number each of the points on the Elevation making sure that the numbers correspond with those on the Plan.

6 Drawing Generators onto End Elevation Repeat the previous process for the End Elevation Make sure that the numbers used are correct and that they correspond to the numbers used on the Elevation and the Plan.

7 Finding points for cut surface on End Elevation Project where the generators on the Elevation cross the cut line of the Cylinder over to the correct lines on the End Elevation Indicate each of the found points with a small dot

8 Drawing cut surface on End Elevation Draw a smooth curve through each of the 12 points found Darken the outlines of the End Elevation

9 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 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

10 Development of Cylinder (2) Draw generators through each of the points found Number each of the generators. Choose carefully where to cut the Cylinder. It is normal to choose to cut the Cylinder on either the longest or the shortest generator.

11 Development of Cylinder (3) Transfer each of the points from the generators on the End Elevation onto the correct generators on the Development Indicate each of the points with a small dot

12 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
