Wall base moulding is applied around the perimeter of a room along a finished floor. It is also called baseboard, mop board or skirting. It can be used in combination with shoe moulding to form a two-member base.
The numbers in these Revit family profiles indicate the cutter number used by the mill in creating the millwork. For wall bases, the first three digits indicate the approximate height of the base. For example, a number beginning in 350 indicates the baseboard is about 3.50 inches high.
