torpid harbor
As shown in the first picture, when doing lay on face on this model I get this. The face it recognizes doesn't match any face in the model.
This survives a re-export in different formats, eg STEP, and the base model absolutely has a flat face in CAD, as it's derived from an extrusion of base sketch lines.

flat is not always flat, the surfaces of a ,stl are actualy lots of triangles, so if you have120 triangles that form 1 surface if only 2 or more points are a 1/10000th of a mm off, there wil be artifacts and a surface that is flat within the tolerances of the cad program , might be several surfaces in.stl files with less tolerance

flat in this case is flat, because it does it from a step too
(sorry for the delay, I didn't get notified)
like, It's from a design in CAD where it's flat, then it's imported as step where it's flat.
I get the step conversion in the slicer has tolerance, but it shouldn't mess a single face that much

it doesnt, if your layerheigth is 0.2, then a sloped surface will look like steps, i.e. look like the elevation map of an area. Just suppose you have 3 layers, and each layer is 0.2, the slicer has to decide if a point belongs to layer 2or 3 and does this by taking the actual coordinate, if that has a z value of lower than 0.1 above layer 1, it is supposed to belong to layer 1, if the z value is more than 0.1 above layer 1, it is supposed to belong to layer 3.
if on a flat horizontal surface there are points that are higher or lower than average, that surface is not flat.it will read as a flat surface with a mountain of for instance 0.0001 mm. just 1 of those will make the surface not flat
I looked into this and found that ever since the inception of Slic3r, all derivatives, (prusa slicer. bambu studio, OrcaSlicer, Creality Print 5.1 and higher) see certain flat surfaces as steps, but that only happens at 0.2 layerheight, change layerheight to 0.16 or 0.24 and the flat surfaces are flat again

it's not 0.2, this happens before slicing too

there... are no slopes
not here
the flat that is seen as angled is completely flat
... and now that I loaded it back up just to show you it worked fine
