Need help I'm baffled this part won't thicken, it's all a combination of lofted surfaces, one small filled surface (triangle) and a ruled surface on the bottom. I need to thicken this to 3mm and don't understand why it won't work. Anyone can shine a little light on this? The surfaces were properly knitted with no gaps whatsoever.
When using the check function I get an "open surface" on the top left corner but I've no idea why.
