First introduced in July 2002, the Business Class M2 Body Builder Resource CD from Freightliner has been upgraded in Version 3.0 to include improved graphics and an expanded viewing area, making dimensions and drawings easier to read and print. The extra room achieved by expanding the viewing area has also improved navigation. Scrolling through multiple pages has been minimized and it is no longer necessary to return to the main menu to start new dimensional designs on a different area of the vehicle. Additionally, a user can select a new base model through the top navigation bar.
