+1 toggle for thin detail/wall support for me
This is frustrating, I end up using other slicers even though I paid for this!!! I don't do engineering, but model trains (in several scales hence some models are scaled down with thin walls), its the likeness that is important over the dimensional accuracy in many cases, so the argument comes down to the market segment Simplify3D are targeting.
If they don't implement a solution to this then they loose this market. I've already warned off several people from buying this software for this reason (two sales for sure... this is costing you money now Simplify3D).
I get "better" prints (for representation of thin details) off my old Cube3D ver2. with Cubify slicer, and I know my FFCP is capable of so much more with the 0.3mm nozzle all metal hot end I have.
If you do fix this I will tell more people to buy your software for sure!
Reading this string I can see although this software is supposed to be user friendly it isn't if it can cope with a fudge factor when necessary. Even if there was an adjustable drop down toggle like "slice thin walls under (select eg. 0.1, 0.2, 0.3, 0.4mm) and print at minimum wall thickness", then people could dial in the dimensional accuracy.
