Bridges and overhanging perimeters

[nocturne compass]

Why are bridges in ORCA defined as overhanging perimeters and dependent on the number of walls in the model?
5wall

2wall

Superslicer does this beautifully with 5 walls too.

The problem above can be temporarily solved by setting this parameter.

But I don't know what to do here. It's not an overhang, it's a bridge. The setting that's really missing is a minimum bridge length, above which Orca would consider all overhangs to be bridges.

What wall generator do you use? Try classic

orca defines bridges and overhanging walls a little differently

bridge, when it covers over walls

overhanging walls

Can I have the model? I want to check my settings.

[nocturne compass]

Both classic and arachne, equally.

We have found just recently (<12hrs ago) that this is really just a rendering error in most cases. If you check the speed color preview you will see that the "overhang" bridge is actually printing with bridge settings and not overhang settings.

I had something similar where bridges seen as overhang as well and switching to classic and removing extra perimeters fixed it

[nocturne compass]

You are right, but it really becomes a bridge if you increase the detail x2.

Cura has had a setting for a long time - minimum bridge length, maybe it would be useful here too?

I have made a request for such a feature.

Yeah, it seems to be a bug in how the preview decides what is what, but apparently doesn't affect the actual printing in this case.

i think this may be a rendering issue
