The Lot Editor (LE) is a tool which allows users to edit or design lots for "SimCity 4" using available props. Because it was released several months before the BAT as a stand-alone version, users at the time were only capable of producing lots that consisted of built-in props from "SC4". The BAT provided users with an updated version of the LE, which rendered the original LE utility obsolete. However, the old version is still made available in the official site.
