Do you watch OCC (Orange County Chopper)? If yes, then you should know they’re using SolidWorks and MasterCAM. I like chopper too!~
Next question: do you know how to design/model a chopper in SolidWorks? Okay, Jan-Willem Zuyderduyn launch a website named SolidWorksmodel.com and the intention of the website is to share with you guys technic to draw a chopper with SolidWorks. It come with tutorials which you can download and self learn the steps to create part by part and end with a devil looking chopper.
