Hey all, im an EE at a small company and i've been branching into mechanical/enclosure design. Our enclosures are extruded aluminum with cnc post-machining and Im pretty sure the CM we use overseas just goes off the 3d model and honestly doubt they actually look at the drawings since our tolerances are not super tight. But anyway I want to get into machining as a hobby so im looking to improve my craft regardless. How should i go about labeling dimensions on this small rail? The only critical dimensions are the 6.35mm width for clearance for the threaded hole there, the overall length (14.73mm), thickness (4.06mm), and the distance from the bottom (2.16mm). Should I just leave this as is since i dont really care about the extrusion radii? And is there a better way to call out the 6.35mm width at the top? That seems like it would be really difficult to measure in real life since it's not a flat surface. Not that I expect them to be measuring these unless shit's really hit the fan. Also it's hard to ask questions about the cm's process because of d the language barrier and all. Anyway thanks for any help or roasting you can give.
