I am still trying to learn ADT 2006. What is the best method for making a floor slab be thicker around the edges. In civil we called it a turned down slab. One of our architects calls it a thickened slab. Po-tay-toes Po-Tah-Toes. I just need to know how to make one in ADT 2006. If someone could point me in the right direction I would really appreciate it.
