I hvae something that I have been struggling for years. Always trying to work around it but I supose I am not the only one. On a typical porch I have an 8" boxed out column. I have a beam above that sits on outside portion of the 4x4 inside. Once you add the 1x column wrap and any skirt board and base mould the colum will typically be 1"-2" outside of the beam. In order to get a lip around the column so that the column itself does not overhang the patio we pour our slab 6" outside of the beam. However when I try to put in a slab it autimatically snaps to the beam. I have tried turning off the clean up on the slab, drawing the adjustment point off the beam, etc. but it keeps going back. There has to be a way to not allow that but I can't figure out where it is.
