Let's say that you have a series of circles to cut out. CamBam allows you to set the start point of the series using the Start Point and clicking on the layout. But if all of the circles are in the same MOP, then CamBam will choose what it considers the best path for the rest which is not always the most efficient IMHO. The way around this is to put each circle in it's own MOP and set the start point for each. You can copy and paste the MOPs so this is pretty easy to do.
On the other hand, for $149, CamBam does a fine job. You could buy a seat of MasterCam for around $8500 and it still does stupid stuff.
