Make SURE you really want to do automatic nesting before you dump a bunch of money. It will pay for itself if you do lots of small brackets/shapes but different designs (they are never the same) . If it's all the same (production) the time you save won't justify the cost. You can lay out a step & repeat sheet in a few minutes. It has to be able to take a DXF file, nest and add-in the leadins or you will just have to edit and move everything anyway. Job shops that do full sheets of changing production can benefit from nesting but for doing decorative or repeat cutting it will spend most of the time idle. Most nesting programs I have seen still need editing and cleanup. It's not as simple as just hitting a button and everything comes out perfect.
