Question about Reverse Engineering Methods

i am an undergraduate mechanical engineer student and on this semester i am working on my thesis. My work is to scan a part with a non contact 3d camera and then create a 3d model to evaluate its geometry.

I have already created a surface model and i choosed  to save it as a *.stp file. I tried to open it in solidworks but my model recognized as a feature and i can't sketch on it  but only on the plane i created based on the nodes or on curves the model has.

I tried to use feature evaluation but the program crashes and i think that is because of the type of the surfaces. I haven't got a geometry based on basic geometrical 3d shapes but i fitted surfaces based on the shape and form of the polygon curves by using a second program.

I would like to ask if there is any way on solidworks to make feature evaluation on free from shape 3d models? Could you please give some ideas to work on?
