it was my understanding, look at the the single slice and does not produce a offset surface around the model. with 0 offset the support will be right up against the bead where the model. A 0.2 offset should be a 0.2 gap horizontally. One setting I did find messes with this a little is the dimensional compensation. so if you have compensation at -0.05 and support offset of 0.2 you then have 0.25 between the support and the printed outline.
this is offset a battle with what you are are showing.
My best way to control support is with two processes. I never like the whole layer skip but a way to control the gap.
One for supports and one for the model. then use the first layer height to control the gap. I can then have 0.15 gap with 0.2 layer height. the difference between the first layer heights controls the gap. something Cura can't do. also you can then control the width bead with this concept as well
Yes there are ways around most any issue, but this is about improving the software. Being able to use auto generation of supports, and not have to worry about non planar surfaces if you use a horizontal offset other than zero. This is just simple math for the computer, looking at each support and deciding whether or not it will stick to parts of the model due to a lack of space, or in areas of support, determining whether or not the requested layer gap is being achieved (regardless of the horizontal offset requested). As the software is now, you have to manually remove any supports that will get stuck to the model, and use a zero horizontal offset in the case of supporting non planar to the XY plane surfaces, otherwise those surfaces will not be supported properly. This defeats the point of autogeneration, since you have to manually remove a potentially large number of supports depending on the model.
