Creating Spiral Objects
Power Duplicate technique

The Power Duplicate feature of FreeHand™ is a great way to create interesting objects or to repeat certain graphics in specified layouts (business card layouts for example). The below tip is one way to use this technique in creating a great looking object that would otherwise be a tedious process.

1) In a new document, create some guides similar to the above example. Here I created two horizontal guides, the lower one 1.5" from the top one. The vertical guide can be anywhere.

 

2) Now draw a line from the bottom intersecting guides to slightly above the top intersecting guides like above at left.

Now with the Rotate tool, Option (Alt) + Click on the bottom point of the line. In the Transform palette enter 20°. It should look like the example above at right.

 

3) While the line is still selected, click on the Guides layer in the Layer palette. This will turn the line into a guide.

 

4) Now using the new guides, draw a triangle shape like shown above. Make the upper left point a curve point and extrude the handles a little. The left slope of the triangle shape should extend beyond the guide so it will overlap correctly later.

 

5) Next Clone the shape.

Special Note

It is extremely important that you leave the clone selected for the next series of transformations. This makes FreeHand remember them for the power duplicate step coming up.

Now with the Rotate tool, Option (Alt) + Click on the bottom point of the triangle shape. In the Transform palette enter -20°. This is the opposite angle amount that we used earlier.

 

6) While the shape is still selected, choose the Scale tool and scale the object from the bottom point. Make sure that the top of the clone is still slightly overlapping the top of the original like shown in the zoomed example above at right.

 

7) Now start duplicating the shape with the Duplicate command (Use the keyboard command to do this very quickly). This will Power Duplicate the Rotate and Scale transformations you applied to the Clone.

 

8) Continue to Duplicate until you get your desired amount of shapes. In this example, continue to finish off the spiral. Almost looks like a shell eh?

Select all the shapes and Group them together. It's now safe to hide the Guides layer.

 

9) While the group is still selected, remove the line. Then give the group a Radial fill with colors of your choice. By giving the whole group the Radial fill, this ensures that the "light source" is consistent for all the shapes.

As you can see in this very nice illustration provided by Judy Arndt, you can use the Power Duplicate operation to create all kinds of great and interesting shapes. As an exercise, see if you can recreate some of the objects above using this powerful technique.
