I am considering buying BobCad Cam. I currently use MasterCam at work and have access to Inventor for modeling. I just completed building a CNC router and have been using cambam but I am looking for something with a little more power and that has a built in simulator.

I will be using the software for programming composite molds and other misc. RC airplane parts. so 2.5D and simple 3D machining.

I am not too concerned with efficiency of the toolpaths, I just want it to work. Is it worth the extra money to get v27? What is new that makes it worth it?

thanks in advance

Tim
