Sharing a new tool that I made for 3ds max. Enjoy 
[ul]
[li]Creating Continuous threads, (for exmaple tanks, escalators,…)[/li][li]Easy To Use! Select your track Items and the spline, click on “Build track” and Ready![/li][li]Live editing and friendly-Rigged so that you can use it in expanding your vehicles/models.[/li][li]Another cool thing is that you can create amzing looking complex meshes in no time with perfect control.[/li][li]These quick examples are made with trackMaker (aprox, 2min for each model)[/li][li]The tool is still in Beta. Ideas so bug-reports more than welcome![/li][/ul]
