I import all my parts files into Vector as .dxf files. In Vector I add the Z depth and do "connect at Z" and then creat the .sbp file. I started to use, for the first time, an Onsrud "O spiral" single flute bit. They do not plunge straight down very well. My question is: is there a way to get Vector to create a ramped plunge when I do the connect at Z?
