I've been trying to build it using the dimensions, however, if I specify the angle wall x and y values, chief refuses to build the walls at my exact values. If I specify 7'10", the program will only do 7'-9 7/8" for example. If I do 4'4" for the x value, chief goes to 4'-4 1/2". I'm thinking chief doesn't like odd angles and is snapping to the nearest whole angle? This is very frustrating for such a simple operation.
