There's a space in the username.

I see a lot of condlines with bad control points.

And some surfaces that maybe should be flipped, from concave to convex.

To me, it looks like you somehow have flipped only the surfaces, and forgot to change also the condlines.

Missing condlines

Ususally LDPE does it all for you, when flipping triangles, it also flips the Cond-Line. I'll have a look , thanks
