identical sketches
and you can see it worked fine for those other shapes
app version 5.480.0.5860 #ebbee53e
ipad air 5th gen ios 16.6
it’s not letting me loft these identical shapes either 
wait suddenly the airfoil is lofting fine. once it gave me the error about vertices, so then i made the trailing edge a little less pointy and then lofting it gave me an error about being an invalid body, and then i tried doing the exact same thing again to take a picture of the new warning, but then it worked fine
i don’t need any help here just passing this along. feels like a bug but cant reproduce now
everything is lofting for me perfectly now. still confused as to why that first shape didn’t work ^^^^
Hello @stuartc23,
We are here to check what could be the cause here and in your other topic, just send us the Shapr3D designs in a support ticket by following the link below:
@KPeter thanks for the quick response. i’ve since deleted those projects. no support needed, just wanted to share the behaviors
earlier i was wondering if there was something inherently wrong with trying to loft this shape in your system:
but i’ve since been able to loft nearly identical shapes just fine so i think it was just a temporary glitch
