I'm new to CAD software, need help busy designing a trailer

Hi Guys,

I am totally new to using CAD software, im building a camper trailer as a project but i need help with actually creating it on onshape,

i kinda know how to use beams and the sketch part i do get (a bit) 

what i want to know is if a create a sketch lets say on the top plane of a square how do i create another plane for the rest of the sides?

    What i would like to do is to design only the Tube frame for the trailer with 50x50x2 sq tube, 

    any help would be greatly appreciated,

    I think it's better starting watching a few tutorial video's, like this one
    You can find more of these video's next to the help menu
    Good luck

    Thank you dick, i will have a look at them, have looked at a lot of youtube videos but none of them helped so far

    And a second tip is to use the Beam Featurescript, that's perfect for creating a tube frame.
    Take a look at this one,

    It may be helpful to go through the first few courses on our learning center:

    To create new planes to sketch on, you can se the Plane feature:

    About learning cad in general, IMHO

    You shouldn't begin with busy project, I would rather take some old work project or hobby project to learn with - too much pressure might make you frustrate. It is possible to learn 3D modeling just using web and asking questions on forum, but if guys&gals in engineering school take courses of few hours a week for couple years or so to learn basics - you can't expect to pull out professional projects after few videos on youtube.

    Of course it depends on person and even more on background but I suggest give it at least few months of intensive night training before putting any pressure on schedule. After ~20 years of 3D cad I would say learning never ends and that's what makes this so interesting.

    Well said! Personally, I like to go around my house and try to model certain objects in it: furniture, tools, etc.. Once you have the ability to replicate something making sonethsom novel will come more natural.
