Great, thanks. I've been quietly following this thread and was going to suggest this.Quote

I'm open to testing the change in the upcoming experimental release.
As a software developer, I understand this problem, often things are affected by multiple elements, but this still means it is worth fixing everything we can.Quote

So, luckily this change won't raise too many complaints since it will change very little. But unluckily, it's not the definitive solution for getting exact dimensions… and probably not the main cause to blame either.

Thanks for doing this. I am sure you are right, but often the easiest way to stop the debate on a point is to prove it by doing what people say and proving your point.Quote

Okay, I confirm I have now extended the usage of the rectangle model with semicircles even in those cases that were previously handled by very similar yet different formulas. The main reason I did this hypothetical "fix" is to stop discussing on a secondary factor that has very limited impact on dimensional issues, but was still attracting too much attention giving users the feeling that flow math was the main thing to blame. Release 1.2.0 will include this minor change (and will also include the XY Size Compensation option which is way more important for handling dimensions).
I've just re-read my post in case I got the tone wrong, I don't think I did. I didn't say you were not producing equally good stuff, or that their quality was only caused by flow math. I worked very hard to make sure I worded things evenly as I didn't want to offend either of you. This is why I said:Quote

CraigRK, I bought parts from nophead as well in 2010 or 2011, and I confirm they were quite good. (Oh, my prints from these days are very good and precise as well, do you want to check? I can mail you one :-)). Saying that their quality was only caused by flow math is unfair, since nophead as a knowledgeable person has always been able to build very good machines, tune them, use good quality filament etc. Even in 2014, the average user can't do all of those. Nophead even invented the polyhole OpenSCAD function that addresses one of the main factors for hole errors lying at the CAD stage. I'm not sure all Slic3r users are aware of polyhole.

I value the contributions both you and Nophead make to the community.

The "outside perimeters first" option was introduced in Slic3r about two years ago or something.
I keep saying that even with this hypothetical -0.05mm compensation, the OP issues are not fixed at all given the numbers he reported. So, my best effort for helping OP is this answer: [manual.slic3r.org]

well, I think you have by far too big ambitions about accuracy with 3d printers. Think about again.
You have a nozzle that can make a line that is 0,40 wide or larger, never smaller. in layer height direction you can select a layer height smaller than nozzle width and by that get better resolution, but in x,y plane, accuracy is never better than extrusion width or at least half of it.

Extrusion width does affect the corner radius in XY plane, so you could say that you can get better resolution in that sense with smaller extrusion width.
