Scissor lift using inventor

I need to make something like the picture that i have attached

What have you made so far using Inventor or is this your first project?

Yes, I know how.

Attach your assembly here of what you have attempted so far.

This type of model can be done with little experience, basically you can do it by extruding the sketch or each part and a few mate constraints and a tangent constraint for the rollers. Once we see what you have done we can advise

Thanks a lot for the replies, i really appreciate it

This is my first project in inventor.

I cannot understand how to start making it.

I donot have any part, i have to make all the parts and then assemble them to make it like a scissor lift.

And what we have learned in our school is very basic use of inventor, and now the professor wants us to make something so complex on our own.

That is actually a trivially simple design.

Start creating rectangles, Extrude and attach your file(s) here.

Post some examples of the basic Inventor files that you have already created so that we can get an idea of your experience level.

I found a great tutorial for you, more or less the same type of model is CadGrab, sign up and download it, it was modelled in Inventor so use the history to learn from.
