Hi

 

It looks like you use 2D plane stress.

 

See what the difference is between 2D (plane strain and stress option) and use as needed – so is your part very thin (plane stress) in the screen direction (z-axis) or is it very thick in that z-dir (plane strain).

 

Still even if the part (stl) is 3D (perhaps due to plane stress option) take it into SC and use the tools there to convert to 3D solid and then copy the face to get a 2D representation of the part. Or create a XY plane and use extract curves tool (Tool tab) and fill those curves to get a 2D surface of the body.

There are many videos on how to do that say one is:
