S3D is great for adding supports manually. This feature request/bugfix is about it's 'automatic' support system, and how it's completely failing to catch unsupported features like previously described and illustrated.
If it encounters a shape like a floating " V ", as long as those angles are within the defined overhang tolerance it creates no support, which is correct. I don't want it to create supports where it shouldn't based on the overhang tolerance. But what it fails to do is support of the base of the V, that's floating in space. Which then causes the entire V print to fail as it extrudes into unsupported space on the base. It appears to have no concept for items like that, which cause print failures on complex shapes without thorough manual inspection... completely defeating the purpose of "automatic" supports.
