The BeavCo Chain Pack features 13 styles of links for creating a variety of chain styles.  This set is great for use with Rhino 4.0 and Matrix design software.  If you are using Matrix 6.0 or higher, you will receive the added benefit of the Chain Pack Installer.  This installer will automatically populate the Matrix library for use with the Object Along Curve utility.  If you are not using Matrix 6.0, you will still achieve great results using Rhino's array commands.  The download will come with a video on how to install and use the BeavCo Chain Pack, the Matrix 6.0 Installer, and all of the .3dm files.

Here's an introduction video to the BeavCo Chain Pack.

Please see the images below for some samples of the chains styles included.
