Stupid flat pack question

[Ramjet]

I'd like to get the flat pack files to the point where it shows the chamfers on every edge of the pieces to make a flat fit on the glued edges. This adds strength and reduces the need to reinforcing in the corners and filling edges, making them sharper.

I also want to design a light laser cut frame that sits inside and prevents any flexing.

   

Ignore the sheet formatting - the idea would be to have a number of large sheets with all the part drawings nested.
The solid lines inside the outline are the lines the bottom edge is chamfered to on the top face, while the dotted lines show where the bottom edge is to be chamfered to.
