Réponse:
Yes, this is possible. Silos/tanks are usually made up of one curved 2D surface. This 2D surface needs to be split into two separate 2D surfaces for the cylinder to be exported into Revit. If it is only made up of one surface, then only half of the cylinder will be exported.
To do this, create a cylinder with one single surface. Then draw a line exactly adjacent to the original line that was created perpendicular to the top and bottom of the cylinder.

Next, delete the surface and recreate two surfaces using the quadrangle tool.
This process is also demonstrated in the attached video.
