Acceptable face and edge stress

[Jamie]

hey there i am designing a small 3m planing hull with delftship free. i am planning to construct using aluminum. when i unpack my drawings to a 2d file there are parameters on the side about edge and face stress. i have around 2 and 1 percent respectively. is this acceptable? im new to this program so im learning alot. any help would be appreciated. i plan to cut my aluminum using a cnc plasma. will this method work using the dxf files? i have attached my plans here. it is just the bottom and chines so far im still drawing the rest.
thanks in advance
Jamie
