STL export only visible shape? Does shape location matter?

I am pretty new to Shapr3D. I have created a lot of sketches and shapes in a single workspace. I have separated several shapes into groups. When it comes to STL export, Does it only export the visible shape and not the sketches and shapes that are hide? Secondly, does it matter where my shape is located in the workspace for the STL export? Since I have created a lot of sketches and shapes, I have moved things around quite a bit which is away from the initial XYZ axis point. Thanks.
