To understand this, try switching planes to see how the image changes. The isocircle you see depends on the isoplane you are in. If you have drawn your object with the suggested dimensions, the center point will be over 2 units and back 2 units from the top front corner of the bracket.ĪutoCAD gives you an isocircle to drag, as in the CIRCLE command. ✓ Use the Snap Mode and Grid Mode tools to pick the center of the surface, as shown in Figure 11-12. If you could not locate the center point, you would have to exit the command now and start over. ✓ Select Isocircle from the command line.ĪutoCAD prompts: Specify center of isocircle:
There is an Ellipse tool on the ribbon and an Ellipse selection on the Draw menu, but these automate an initial option and do not give you access to the Isocircle option.ĪutoCAD prompts: Specify axis endpoint of ellipse or : In our case, it is easy because the center point is on a snap point. You must be sure that you can locate the center point before entering the ELLIPSE command. Often, it is necessary to locate this point carefully using temporary lines, object snap tracking, or point filters. To draw an isocircle you need a center point. ✓ To begin this task you should have the bracket shown in Figure 11-11 on your screen. Isocircle: The elliptical representation of a circle in an isometric drawing. In this task, we use the latter capability to construct a hole in the bracket. The ELLIPSE command can be used to draw true ellipses in orthographic views or ellipses that appear to be circles in isometric views (called isocircles in AutoCAD).
