to make curves at this stage though, unless you’re an experienced user. Just click out a rough, angular shape and make sure you close it by placing the last point over the first and clicking. Figure 7 by drag direction, distance or position. Spherical gives a flatter, rounder looking surface than angular or dimpled (which produces a sharp topographic surface). You can see examples of the different shapeburst Shapeburst gradients.
