You can use `slicer.util.loadSegmentation` for loading a segmentation from file.

Note that in recent nightly versions of Slicer, you can export segmentation directly to stl or obj files. See [Save segmentation directly to STL or OBJ files](https://discourse.slicer.org/t/save-segmentation-directly-to-stl-or-obj-files/2428) post for details and [API documentation](http://apidocs.slicer.org/master/classvtkSlicerSegmentationsModuleLogic.html#a9578121589a3b5e20a05aa8dce33c642) for description how it can be used from script.
