something i stumbled across some time ago but deemed to be less important at first but encountered recently again: when i have a surface which overlaps visually either self intersecting or overlayering and use the Silhouette command i get nothing more than just a plain dupBoarder instead of an outline.
the same is for simple boxes or other rectangular or multisided extrusions. meshoutline does what would be needed but its not usable for curves because it creates polylines.
can this be improved? i have no idea if this works on windows but i believe it might be helpful to have it working as an actual silhouette and not as a dupboarder. i know there are work arounds but sometimes it can get more complex to intervene manually.
