And still.. I'm VERY confused about setting up tool offsets. I have a simple piece.. a circle with smaller circles cut into it. OBVIOUSLY the tool must travel the OUTSIDE of the bigger circle, but INSIDE the smaller circles... this simple task seems all but impossible. DO I have to create my CAD drawings compensating for the tools myself? If I want a one inch circle, do I have draw a 3/4 circle to compensate for the tool? That doesn't seem right!
Unfortunately you do have to purchase LazyCam to use Offsets and pocketing so you are correct in saying that you can not try out those features until you purchase the license for it. If you did indeed watch the videos, it's no wonder you're a bit confused on how they work because they don't with the free version. I can assure you though that it does work but keep in mind this is still a BETA program with not a lot of "written" instruction so it may not be for you.
Unfortunately CAM programs do cost money and sometimes quite a lot of money but for the time they save, they can ne worth it to some depending on what's being fabricated. To give you some comfort in LazyCam, I was in the same boat as you about 6 months ago and had no idea what I was doing with any of this software, especially learning any CAM program, but I'm easily making parts now from all the help from the fine folks here. Maybe do some searches in the LazyCam forum about the questions you're having as I assure you that they've bveen asked before -
