3.16 Curves in Isometric
You can draw curves in isometric using a series of offset measurements similar to those discussed in Section 3.12. Select any desired number of points at random along the curve in the given top view, such as points A, B, and C in Figure 3.48. Choose enough points to accurately locate the path of the curve (the more points, the greater the accuracy). Draw offset grid lines from each point parallel to the isometric axes and use them to locate each point in the isometric drawing as in the example shown in Figure 3.48.
