I agree, some are an issue as you have described and each takes that on in there own way. I see many parallels in our thinking as well as many that are not. This is also mindful of a few things that dictate one's situation. Such as machine capability, ones ultimate end task of what % is machine and hand work, There are many variables that must be addressed all at the same time.
I still see so many that think CNC is plug and play. We know better. Bizman62 is understanding the complexity of it now, as are many others as well..
As far as work holding for instance I use a flanged ear approach using location pins and screws for the body. Like I said we each use and choose directions in CNC that make sense and apply to our application. I prefer to model in full 3d where I can and not worry as much about the 2d parts of that. It is the approach that I use. The 2d parts are my map for the 3d model. Again this is something we could discuss for a long time with most likely no end to a proven or best method. Learning from each other though does at least open doors for more intense review of a process.
Looking good Carl..

A sample of my holding of a body. This allows me to continue until I am ready for final profile cutout. When I removed the back to open this I then after have to go back and adjust the ears once a new removable back was made. This is an extreme that I normally do not have to focus on.
