In 2015, you have Pro Platinum and Pro Basic. Basic was a scaled down edition of Platinum, but still had ACIS Solid objects.
In 2017, they discontinued Pro Basic and replaced it with Expert. This is basically Deluxe with some extra tool sets. The 3D objects are TC Surface, not ACIS, so they will be faceted. You won't have all the nice extra tools that were part of the ACIS toolset.
