I can design my own mech from the chasis up?

A friend of mine just asked this question on a local group and I thought I could field it.

It's from Classic Battle Tech.

Yes you can build your own Mech but it's kinda hard to do with pen and paper. You could save hours of your life and just buy a program called "heavy metal pro". In fact if you are going to play CBT it's almost must have. It lets you do up custom mech sheets for all of your mechs and in minutes.

One other very nice activities you can do with it is share files on weapons, mechs and etc. between you and your friends.
