# Iterate

Show/Hide Hidden Text

This Transform menu command has three forms: Iterate, Iterate to Depth, and Terminal Point.

| Iterate and Iterate to Depth Commands

Selection prerequisites: Some combination of one or more pre-image “seed” objects: •Independent points or points on a path. These points must define other points in your sketch. •Parameters or independent calculations. These values must define other values in your sketch.

To enable the Iterate to Depth command, you must also select a single value that determines the depth of iteration. This value must be the last object selected, and you must hold the Shift key when choosing the command.

Geometric Iteration: Midpoint Triangles | Numeric Iteration: The Fibonacci Sequence | Combined Iteration: A Fractal Fern

When you choose either Iterate or Iterate to Depth, the Iterate dialog box appears so that you can specify the mapping that defines the iteration.

When you choose Iterate to Depth, the last value selected dynamically controls the depth of the iteration.

Suggestion

Sometimes you may want to create an iteration that begins with a constructed point or a calculated value, even though the Iterate command does not allow you to use such points or values as its prerequisites. You can often get around this limitation. First construct the iteration separately, creating independent points and parameters to serve as the seed objects. After you’ve created the iteration, merge the independent points to your desired constructed points, and edit your parameters to change them into calculations based on other values in the sketch.

| Terminal Point Command

Selection prerequisites: A single iterated point image This command constructs a point at the position corresponding to the very last step of the iteration. If the depth of the iteration changes, the terminal point moves accordingly. |
