Calculate rounding

[nikolajholdt]

Hi All

I'm new to Fusion 360 and modeling in general, so please bear with me...

My "issue" is, I want to make the model below, but I cannot figure out, how I make the correct rounding for the object to fit. I do have the measures for how wide and tall it is, but there needs to be some kind of angle calculation or measurement, but this I cannot figure out - hope someone can help.

This is the model, please notice the "inner" rectangle, it's these roundings I need to get right:Model

 This is the measurements:

This is my model so far in fusion 360 (I've tried numerous kind of things):

It would be easier to help you if you attach your Fusion 360 model to the thread: File|Export|Archive file *.f3d

If you have a scanner, then you should be able to get an accurate image which you can import into Fusion 360 as a decal.

If not, draw, then print, a set of arcs that are close to the size. If you print them on tracing paper,  you'll be able to match the printed arc with the actual arc.
