Can UPnreal Engine 4 import custom Bulder Brush (BSP) primitives like Ue2.x could (.dxf)

you don’t quite understand, it’s for reference as a brush, upon importing a SM you cannot easily edit vertices to fit Landscapes. Al;so, if i wanted to make Home-model with unknown metrics, it would assist that as well, i haven’t tied down what game i will be building for atm.
