The features that are generated using the detect features step of scenProc are not simplified. Before these polygons would be a bit blocky because of the raster image that has been converted into the polygon. But with the simplification a more smooth polygon results. In the image below you can see an example without (left) and with (right) the simplification applied.
The simplification makes the polygons less complex and therefore also reduces the size of the AGN files. And with this simplification it also becomes possible to use the feature detect polygons for buildings. For the blocky polygons it was not possible to calculate the best fitting rectangle correctly, but for the simplified ones that no longer applies.

As you have most likely heard by now Microsoft has stopped supporting Windows XP as operating system. I know there are still many users using my tools on Windows XP as well and the decision of Microsoft doesn’t mean of course that my tools will stop working on Windows XP.
I have returned from my vacation yesterday. As usual I don’t bring a computer on vacation, so I haven’t done anything on FSDeveloper or my tools in the last 3 weeks. But of course that doesn’t stop my brain from coming up with new ideas. Luckily I had brought a notebook (you know, a paper one) to write those ideas down. So now I have returned full of interesting ideas to try again.
