This is likely to be another 'how many ways can we skin this cat' type of thing. I'm making a small frame that will have another piece inserted into it during the print process. Simplified, it looks like this:
And a closeup of the inset part:
When I'm making this, I break it up into three "layers", the bottom part, a center (which is smaller dor the inset) and then the top, like this:
The bottom and top get an inner chamfer and all three together get the outside rounded with a fillet. For the most part, this works. Especially when the bottom layer has other stuff, like sometimes instead of it being a six sided frame, I will fill the hole with some sort of design, then the center one and the top one which are just a six sided frame.
However, the one thing that annoys me is if I forget to do something on that bottom layer, or if I need to change it a bit, many times it affects the next two layers to the point where I need to completely delete them and redraw. So my question is, is there a better way to do this? Or what I'm doing the right way to go about it, keeping in mind that the bottom layer can be different in the middle, but the outline is the same as the rest.
