Parametric Depth

When you define an iteration, you can use a measurement, parameter, or calculation in your sketch to determine the depth of the iteration. After you select the points or parameters that define the pre-image, but before you choose the Iterate command, also select the value to be used in defining the iteration depth. Hold down the Shift key while you pull down the Transform menu, and the Iterate command becomes Iterate To Depth. Choose this command and use the Iterate dialog box to define the iteration normally. Once the iteration is defined, the integer part of the value of the selected measurement, parameter, or calculation is used to determine the iteration depth. (If the value is negative, the depth is set to zero. If the value is too large to display all the iterated images, Sketchpad uses the maximum depth at which the images can be displayed.)

If an iteration’s depth is determined by the value of a parameter or calculation, you can’t use Properties to change the depth.
