I do a lot of boundary polylines to get the areas in CADian 2011 using boundary command & I""m happy with the result but I find there is a difference polyline boundary created in CADian 2012 when applied at the same drawing. I will send the file ec_1003-1 after hide.dwg to help@cadian.com. Please try on LIVING room area(Cadian 2011-created inner polyline boundary but Cadian 2012 created Outer polyline boundary). Is there a way to get the same created polyline boundary in CADian 2011 by using CADian 2012?
