I am trying to shell out a simple part and it soesnt seem to be working right. It is basicly a box with a 3 degree draft and a .5 in fillet on the edges and base. I shell it out with the walls measuring .06 in. When i do this and use the measuing tool i find that my wall width is 0.06008234 in and will contiune on to longer decimals. It is not an exact number. But if i remove the draft and then shell it out it comes out to be right. What am i doing wrong? Why would the draft change the way that is shells? Thanks.
