The answer to your question is Dolphin will do this for you automatically and easily. You do it by using the area clear function in our CAM program. You will draw just the outside shape in DCAD and then use the DCAM to do an area clear and that is where you will tell it the step over you want to use and the tool information. I am going to make a simple video for you in the morning. Also feel free to go to our website (www.dolphincadcamusa.com) and check out the support page. You can call that phone number and I will be glad to help you out.
