Have a read of this thread: viewtopic.php?f=23&t=3471
This must be the most discussed subject on the forum....and its about time Simplify3D took notice and did something to satisfy its users!!!!

Re: Slicer losing thin walls/details - NOT A BUG
Hello.
As far as I know, the path solver approach is quite conservative.
That means, if the extruded filament path goes out of the model bounds, it won't be calculated/extruded.
But fortunately there's a workaround.
In the "Extruder" tab, we've got 3 important values:
1. Nozzle Diameter
2. Extrusion Multiplier
3. Extrusion Width (Auto - Manual)
We'll focus on the last one, the "Extrusion Width".
Despite his name, it's just a value that tells to the solver how to behave.
While the first two values could change the extrusion in real world, the third set the virtual space between two paths.
So, putting an Extrusion Width at 0,10 with the Nozzle Diameter at 0,40 and the Extrusion Multiplier at 1,00, will not change the extrusion size in real world, neither change the real volume of the extruded material.
What changes is the solution of the path. In this case u can put 3 shells in a 0,4mm wall using a nozzle of 0,40.
BUT YOU SHOULD BE AWARE THAT THIS WILL LEAD TO THE OVEREXTRUSION, POSSIBLE NOZZLE CLOGS, BAD PRINTS.
I found it not a bug, but instead a solution for small holes and wrong external dimensions due to overextrusion (read Slic3r).

Io non credo in un Dio personale, non l'ho mai negato e anzi l'ho espresso chiaramente. Se c'è qualcosa in me che può essere definito religioso, quella è la sconfinata ammirazione per la struttura del mondo così come la scienza può rivelarcela.

Re: Slicer losing thin walls/details
Just wanted to add a quick note to this old topic to make sure that everyone was aware that Version 4.0 included many changes to how thin walls are handled in the software. There are now quite a few new options so that you can customize exactly how thin walls are printed. For example, if you wanted to print a 0.3mm thin wall using a 0.4mm nozzle, you can now do that and you even have options to pick the exact width that the extruder tries to use.
I will provide a few useful links below that explain the new features

Thanks for reporting the issue!
