I have created a brep by using railrevolve. It has a negative volume.
Does it mean that the surface vectors are in a wrong ditection? How can I fix this?

Try to relocate your geometry near the origin point and calculate the volume again.

Does location of the geometry matters for the calculation of volume ?
Negative volume usually means the surface normals point into the volume.
Usually only if the object is a very large distance fromt the world origin. Your object does not appear to be that far away.

Depending on the direction of the curves, the volume might be negative.
