Not sure why but it seems there is no way to insert a catchment table into Civil 3D. We are entering all this great information into the catchment objects to export for storm analysis but have no way of displaying it other than the catchment label. Having the ability to insert a dynamic table similar to parcel tables would save a lot of effort in having to recreate this information and would allow the engineer to only have to focus on making sure the objects were right in the drawing instead of having to remember er to update the spreaf sheet or table as well.
