These filters all operate on the selected ( or partially selected ) art to produce new artwork. Partial selections refer to the process of selecting only part of a path using the Direct Selection Tool.

Simple examples of all are shown : refer to the documentation for more info or options : additionally you can double-click on the tool for the appropriate dialog box.


This is an alternative to Illustrator's native Roughen tool with the advantages that it is reproducible, has identical effects on coincident paths, works on partially selected art and has different modes of operation.

Here's an example with an ellipse that has been split with the knife tool. The common boundary has been roughened using a fixed angle of 0 degrees. It can be seen that the common boundary is treated in the same way for both path segments.

Roughen example

Here's another example using the 'centre' option

The crenellate filter "adds" an open path to the existing path in a repetitive way. For example using a square crenellation on a circle results in a gear.

A variety of pre-computed open paths are supplied : in addition the user may select an existing unclosed path as a crenellation.

The roulette filter generates "spirograph" type art. Example : Roulette example

Other filters (Simplify, Straighten, Smooth & Reverse path)

The other filters operate in the expected way.

Simplify provides a way of thinning paths in AI7 or 8 ;
Smooth and Straighten do what you might expect ;
and Reverse Path is a utility filter that reverses the direction of a path (only noticeable if its brushed or part of a compound path).
