Your surfaces are imported mesh files and will not play nice with the surfacing/modeling tools. They also have holes in them shown here. You will have to recreate the surfaces using the mesh mesh as a guide for onshape tools. Or you could edit the mesh in another software. Not the easiest to learn surfacing on that particular set of surfaces. learn.onshape.com has some great tutorials to get you started
I was feeling ambitious and fixed your STL file. It is now a watertight model that can be 3D printed as is or edited with onshape tools like extrude cut/add. but not tools like thicken.
Not going to happen in most mechanical CAD software. Plus, the stl is pretty bad. Besides the missing surfaces as MDesign mentioned above, it's very coarse, and will look bad after printing. Best bet IMO is to try to find the original author and see if they have a STEP file they can share. Or, one of the mesh softwares might be able to do it (I've never used any, so can't recommend one).
That looks like the motorcycle front fender excercise I've seen in CAD training courses. There should be real surface models of this out there. Else, it is still a good exercise for surface modeling, also for Onshape users.
(BTW.: The scale of the model appears to be all wrong.)
