Can't create fillet between two bodies.

I've created a pad and loft in FreeCAD 0.19 and combined the 2 bodies using the boolean function. I now want to fillet edges 13-15, but I just get "Failed to create fillet".

Fairly new to using FreeCAD and filleting is the thing that I'm struggling with most.

You don't need boolean to create your box.
Additive loft is simply the next feature in the box body.
As for fillets... all CAD systems are struggling with them.
You are asking for a lot

So FreeCAD can easily cope with what I have drawn, but whether it is what you need is another story...

Maybe someone who knows more than I do will come up with an answer. but somehow I doubt

Unfortunately the dimensions I made mine are the dimensions it needs to be.

you must all do in the same body
I don't understand why if I do 2 Pads, one on top of the other it doesn't work, the dividing line doesn't disappear after Refine = true, it annoys me

But if I take the opposite solution: a big box then remove the support leg, the result is perfect

but the loft is missing, so the walls are not tapered

Two things here, a pad is ok because one can use a draft.

A big loft is ok because the excess can be pocketed away after...

smiles all round

Good point, I have forgotten about it

but I am still left with the fillet that OP wanted (along selected edge) and it just doesn't work ... (at least for me)

Ho

I had not seen this detail
I propose an acceptable solution (I hope) by making a pocket high enough to make the fillet and the Draft on top

Well... it would be good enough for me

Draft is a vulnerable function as far as the topological naming is concerned - similar to the fillets.
