It can easily be, although if the CNC part of the project is all there is, I can see why people might think not.
I design projects in sketchup (times move on) rather than pen and paper. I decide how each bit will be created as I go.
If a part of the project is best created with a hand tool, I use that. Same for power tool parts (times move on), same for CNC produced parts (again, times move on). Some parts need a combination of techniques.
I guess it depends which technique produced the biggest percentage of the project. If CNC parts augment a project rather than are the project, to me the project is still woodworking as without woodworking skills the product doesn’t come together.
