When I try to bevel the floor it does not make the curve, it's always completely straight.
Try pressing Z while you are beveling or after you confirm open the last operation panel(Bottom left of the 3D viewport) make sure that the profile is at 0.5 and that profile type is set to superellipse.
Hi Gabriell ZZeon ,
You actually have so-called 'double Vertices'; you can see that the Bevel only goes along one Face.
The Edge that you are trying to Bevel, are really 2 Edges 'on top of each other'. You have only one of them Selected and that's the one that gets Beveled. It can onmly go into one direction, because on the other side it is blocked by the second Edge.
So, Select everything (with A) and then, M > Merge > By Distance.
