Not sure if anyone will find this useful but I needed something that would make sure my level blocks I was making in 3ds max were convex so I could take them into wed.
http://www.melax.com/3dsmax/ this is the website to download the plugins
and this page explains basically what it does
http://www.melax.com/3dsmax/hull/index.html It creates a hull for any object thus making it convex, and so far its the closest plugin for 3ds max without spending money that I found.
I should add the plugin is for 3ds max 7
