PCB Dimensions are incorrect

[wleismer]

Hello,

I recently defined a 2D PCB board outline by creating a 3D PCB to fit my enclosure.  I was able to route and place components just fine on this 2D PCB, however when I went to generate the CAM Preview, I realized that Fusion 360 thinks the board size is different from the actual.

Actual board dimensions are something like 79x100mm, while Fusion 360 reports it as 196x570mm.  CAM preview is way way zoomed out. I thought maybe something far out like a component or "Dimension" line was causing Fusion 360 to calculate a huge board size, but I cannot select anything when I click and drag in that empty space.

Is there any way that I can figure out how/why Fusion 360 is calculating such a large and incorrect board dimension?  It makes it impossible to confirm the CAM preview, because zooming in results in an extremely blurry image, and I'm concerned that the Gerber output will be incorrect or have some error.

Hi @wleismer ,

I hope you're doing well. Turn on all of your layers, my gut feel is that there is some item on the board that extends past the limits of the board. The ultimate source of truth for your board is in the manufacturing data, so I always encourage users to check their gerbers in a gerber viewer.

Let me know if you continue to run into problems.

Best Regards,

Ah, you know what, I had to turn on all layers and found some things in the "Value" layer sitting really far out in no man's land.  Thanks Jorge!
