Are you trying to extract the internal fluid which has the L shape pipe, that connects to the cone shape and big cylindrical shape? Do you have cavity in all other parts but the L-shape pipe? Could you try detach the two end circular faces of the L-shape, which will probably convert that solid L pipe into surface. Then you can stitch this surface to the rest of the structure, and do a volume extraction. If this doesn't work, you can probably grab all the interior surfaces, including the cylindrical faces on the L-shape pipe, copy and paste them into surface bodies, stitch, then patch the ends with missing face tool.n
