How is in the name of Ritchie and Kernighan this bridging supposed to work?
Is anyone even looking at these bug reports? The bridging bugs are starting to really prevent Simplify3D from being usable
The whole point is to not use support and to do this as a bridge (Slic3r manages to do this properly, Simplify3D was doing it just fine on previous 10 versions of the object, this version is slightly different dimensions, same shape, and then the bug hits and the wrong bridging is calculated, when I change dimensions again Simplify3D again works ok, problem is this is the dimensions I need). Support works with Simplify3D, bridging is riddled with bugs. This time I need bridging, not support.horst.w wrote:use support

I help myself using Slic3r and I try to help us all by posting a "reproducible test case". Fixing a bug when you have a reproducible test case is usually simple; always lot simpler then when you don't have a reproducible test case.horst.w wrote: Bridging is one of the poorest function of S3D and improvement thousend times requested.
Live with it or help yourself.
If you look at the code produced by the slic3r you see that it can be done. Also I can snap a picture of the printed part that came out perfectly (and it's ABS so not a material as easy to bridge as PLA) so you can see no loose wires at all - perfect strong bridge.brian442 wrote:Looking more closely at your STL file, I think the issue is that there actually isn't anything to even bridge between!
That's the point of bridging - bridging a gap - no support underneath. There are 2 parallel walls between whom you can print a proper bridge. It would be better if those walls are thicker then 1.8mm but it is enough. It was enough for the same part for Simplify3D with slightly changed object (the bridging part was not touched) and it's enough for Slic3r. Bridging is a real thing, it works, and it's often required for a proper print. Support is good to have, also often required, but in this case bridging is a better option. Adding support underneath it to solve Simplify3D bug is just not solution.brian442 wrote: If you look at the top-down view, the region where you are doing the infill has absolutely zero support below it.
?! there is a wall on one side, and wall on other side. A classic bridge, you anchor line on one side, run a line from one side to the other and anchor line on other side. Just like Slic3r did, just like Simplify3D did for that same object if you change things "a bit". What "foundations" are you talking about. This is a clear bug in Simplify3D, nothing else.brian442 wrote: There's no foundation to even bridge between.
How can it succeed ?! you go from edge to "nowhere" and back and except filament to? levitate?brian442 wrote: With that being the case, I would actually PREFER that it goes in this shorter direction, since that is much more likely to succeed if there is absolutely nothing below it to support it.
what is it grabbing on to when doing short extrusion?brian442 wrote: So I for one prefer the way it works in your original screenshot, and I'm honestly not sure why the software would ever choose to go the direction you are showing, since again, there's nothing below it for those long extrusions to grab onto.
