how do i do a 5 meter hydraulic man lift in solidworks? anyone with a similar project please help asap
Maybe you can get some ideas here.
Check out the 'sketch blocks' tutorial in the 'advanced techniques' Solidworks tutorials under the 'help' menu. It's a crane instead of a man lift, but the concepts should be easily applied to your project.
Simple, sketched layouts are always a good place to begin, and you can use the layout to evaluate and drive the rest of the design.
