I have been using the CNC for about a year now. Playing around with some simple signs. I'm interested in getting into doing some 3D modeling now. I have started off with free files from Design & Make. I've watched lots of their YouTube videos but one thing is still confusing me. I have the basic Retro Sign image. I've included a screen shot of the shape and base height. I'm not wrapping my mind around what these really are. So here are my two questions...

1) Is the base height what I can expect the thickness of the flat panel portion of this image?
2) With the settings I have... what should my start and cut depth be for my profile toolpath?

Any help would be great.
