http://www.bikechecker.com/. it is a CAD for bike suspension but the realy cool thing is that you cn compare the axel path of different bikes and suspension designs. You will be surprised at how far off vertical some suspension designs are. Make sure you go to the online catalogue of bikes though because the standard ones are mostly pretty old bikes but the online ones are largley late models.
LoL thats pretty cool but weird when you said can i thought you meant AutoCAD oh well my bad i have a pic of a bike that i drew in autocad 2007 i will find somewhere to post it. it took me 6 months to draw it(the rotor took 8 days alone)
Cad stands for Computer Aided Design. (or something like that) so the term cad is used for all design programs

yeah i know that mate. i got this years version of AutoCAD for free instead of $8000 (i stole it from school). i wonder how much Linkage v2.5 costs. it would have taken them a fair while to make all the drawings
