OBM is limited in the cap shapes it can accommodate currently. It would be very helpful if we had the ability to draw cap shapes in the front elevation view and use those as templates, which OBM extrudes in the up/downstation direction. We would literally be able to do any cap shape we want if we had that ability.
The same issue occurs in the vertical direction. For example, I have a pier with an inspection hole at the top, but there is currently no way to position this hole at the top level of the pier.
