Yes, this is correct...but if you have enough of an overhang with too much space below then several layers drop down like spaghetti resulting in no solid foundation for the subsequent layers which leads to collapse. That is like saying as an architect designing a house on a hill to tell the construction foreman to just drop the bricks that would normally be used for the ground floor of a high-rise to "just let them pile up on the side of the hill there and hope that bunch of rubble is enough to hold up the rest of the building".

Your results are less of an "as designed" depositing of extra material and more of a "happy accident" because there space underneath was so small that the incorrectly deposited strands just so happened to fill it up. Try that with a much taller build and on a steeper slope. Things will come a-tumbling down!

Re: My supports need supports!

Exactly how wide are you trying to make your supports on these models with difficult places to adhere supports to?

Re: My supports need supports!

Well there is a gap there so the support doesnt bond directly to the model. This distance is all adjustable. On models with steep surfaces you need to play with the lower seperation layers and the offset from the part. I keep my offset usually at .5mm but you can adjust that closer. .3-.1 might work better for you.
