Problems with "phantom" Pressure Pipe in IFC file

[marcelo.wanderley]

Hi everyone,

I have a problema in the IFC file exported from C3D 2024.

It's a Pressure Network that's look perfect into de C3D, otherwise, on IFC File, there're a "phantom" pipe togheter my pipes. This problem only is showed when I have curves in the network.

The same curve into C3D.

I really apreciate some help.

Thank you so much!

I cannot tell from your first screenshot, but it almost looks like what happens when you have a surface that needs a boundary applied to cut off the internal triangles.  It is possible that IFC does not support curved pipes, so this is how it copes with the data.
