This plugin filter for Adobe Illustrator connects two or more selected paths into one continuous path. You choose how close the endpoints must be to combine the paths, how close to tangent the endpoints must be, and whether to average the endpoints and control handles. It’s especially useful for cleaning up CAD drawings, GIS map data, and other files that have been converted to Adobe Illustrator. It’s especially useful for tasks like connecting and filling state/country borders in vector map files.


The plugin also includes Assimilate, which will search out unselected paths that are within the distance and angle you specify, and concatenate them to a selected path.

Concatenate and Assimilate items are added to the Object > Paths menu giving two methods of calling the plugin, plus the option to assign a custom keyboard shortcut.

In addition, Concatenate and Assimilate functions can be recorded as Actions in Adobe Illustrator. When playing recorded Actions, Concatenate will use the settings at the time of the recording, but will not change your current panel settings.

This plugin is included in the Productivity Pack bundle. Requires either Adobe Illustrator CS3-CS5 or CS6-CC for either Mac or Windows.

Notarized for macOS 10.15 Catalina with Illustrator 2019-2021.
