I'm fairely new to computer modeling and I've been experimenting with DimXpert and Tolanalyst. I'm confindent i'm using these features correctly but when I compare my tolanalyst max and min to doing it by hand, i'm getting a difference of around .100. I've tried different contraints but all are yielding similiar results. I'm using Geometric for DimXpert. Is this something to be expected or am I doing something wrong? My manual calculations have been checked by Professor and T.A. and they both agree it is correct.
