I always have lots of fun with family tables ( 
). I have any assembly cut of a tube that has holes stamped in the tube. There are two standard lengths of tube with two different numbers of holes (hence the family table).
Now I am performing a cut on one end of the tube. I have offset a plate (Bottom) from a plane on the assembly (Top). I am then using this plane to set up a cut to remove material from the assembly. The problem I am experiencing is that the cut dosn't always happen and I, for the life of me, cannot figure out why. The assembly cut is made on the generic of the family table. One instance comes out correctly (first picture).
The second instance does not.
I have tried several different cuts - using the front, right or bottom plane for the primary plane of the cut. I do through all to make sure that I get all the material. Any thoughts on this?
Thanks, Dale
