I was wondering about that as well - everything was designed by the time I ‘arranged’ the sides. I had actually noticed the tiny discrepancy in the design but thought that it was related to some joints to bring the walls in. I figured that the walls were selected individually for the arrange and there is no relation to the individual components when ‘arranging’ so it makes no sense … but hey, this isn’t the first time that Fusion did something that made no sense.
Since the design will be my standard from which all future drawer boxes will be made (highly parameterized) , I will make a fourth file to fix things right in the design stage so this doesn’t catch me off guard sometime in the future.
@Jens Understood. Tks. A couple of minor things that you can consider, too. First, a downcut end mill will likely give better results than an upcut. Second, since the actual dimensions are quite critical for a good fit, verify that your end mill is actually its advertised size. (Now that I think of it, in your case, it may not be important since all the cuts would be off by the same amount.) However, it won’t hurt to check. I found out the hard way that one set of my “1/8” bits was actually .118, not .125.
Since it appears that the issue and solution are related to Fusion, I’ve moved your topic to the Fusion category. Future advice seekers may be able to find it here more easily.
Nice find @NeilFerreri
@Jens, keep us updated on your progress!

I am happy (maybe even ecstatic) that the mill run this morning was successful. I have glued up my test box and will post a picture once it has set.
It isn’t perfect but I am 99.9% sure that this can be fixed with some double sided tape to make sure the stock is sitting flat against the spoil board. Even with the small error, it is quite usable.
I think I will be looking into some sort of vacuum hold down for the future to avoid issues since it is hard to make sure a 4ft * 4 ft sheet of stock is totally flat against the spoil board.
I must say, I am floored by the fact that a 0.4 mm error would lead to the mess of a box I had earlier. When I was cutting things the old fashioned way, I was aiming for a tolerance of 0.5 mm and I have several cabinets that came out OK with those tolerances (and even the possibility of stacking of those tolerances).
I am using a 1/4" SPE Tools down cut mill - a quality tool. I will verify the dimension later but I expect it to be right on as SPE makes nice tooling (at reasonable prices, especially in their 5 packs).
