Hello,

i have a problem with importing coordinates of a blade into TG.
The Blade has 5 Profiles. I defined the Profiles like usaual with:
# Profile 1 at 0.0% (hub) ....
But i get the error: Trim oepration failed to produce any surfaces...
This Error was discussed before here. The solution was, to define TE and LE in the file.
And I tried to do this like explained. But it doesn't work. So I wanted to check, if I defined te TE and LE right.

In the picture you can see the profile at 75% Span. On the others, I marked whicht points I defined in the .txt-File as TE (TE2) and LE (LE2).

Is this right ? Or do I need to set the defintions at other points ?

Thank you for your help!!

Fixed it by myself.
Don't know why, but the 100% Span Points weren't in Order.
Now it works
