Hi Clive, yes it was nice to put a face to a name after meeting you last year. Alphacam also allows you to put a box around a drawing to join and form a closed geometry, but if the break is too large it will not join them and lines/arcs need to be extended/trimmed before the join can be completed. That is what I meant when I said "cleaned up". I have never used Autocad, but suspect that most of these programs are basically very similar. For me tha advantage with Alphacam is that when a drawing is completed, the cutter paths can be put on in the same program and the G code is then automatically output and post processed to suit the machine. I like it nice and simple - I suppose that suits my mind!!! G.
