At KYTC we like to show the vaults of drainage structures, in order to do that S&S drew them for us. ORD does that in 3D, however, we turn the 3D off when producing plans.

It would help in the case that we could point to two cells (one that matched the regular structure and the vault 2D version) instead of remaking hundreds of cells.

It's not dire that they be on different levels, but that would be a bonus.
