OpenSCAD is just a generator. You cannot query generated or imported geometry in any way. Not even calculate bounding box which can come handy if you want to place something on top of your model etc.. Equally big problem is schizma between modules and functions. Functions can't draw anything but can return values. Modules can draw but can't return anything. So you cannot even calculate the bounding box (or anything similar) yourself even without STL import. CadQuery on the other can do queries.. give me bounding box. give me a second face parallel with XY from this point in direction of +Z. Btw. FreeCAD bugginess realy varies. I have had a much better experience with a package built from master on Gentoo and Nix than with the stable appimage.
