Problem to close brep

Hello! :wave:
I’ve created solid (bridge joint) with section and there are some problems:
1 incorrectly solid;
2 Open Brep;
I tried to rebuild curve - created new points and this didn’t lead to a result.
I will be glad of any help (17.9 KB)

Scale up your curves. Tolerance problem.
