Section fill oddity

[simoncbevans]

Can anyone help me understand what is happening here?

Here is a section showing one floor of the 2 storey house:

And here is one showing the other floor:

The thicker outer walls are in one group and the thinner internal ones in another. On one floor, the section fill correctly fills the walls both internal and external. In the other, there is no fill to the internal walls but two enclosed areas are filled instead.

Whatever I do to try to correct the infill has failed so far. Bet it’s something really silly!

I attach the SKP file:

Fix the stuff indicated by Solid Inpsector2.

Once you’ve done that the section fill will be displayed.

There’s a few errors with the geometry on your internals walls. Fix that and it should be ok

Dave beat me to it!

Thank you both. That sorted it!
