In a recent OBM video I see an option to have the abutment "BackWall" conform to the top of the deck. I think it would be more common to have the backwall under the deck. Is there an option or method to have the deck extend out over the top of the backwall?
You are right Mike, currently this option is not available in OBM. We will implement this in a future release in the short term.
Along with this, it would be helpful to be able to specify a minimum offset/gap between the top of backwall and bottom of deck.
Yes an offset can be provided.
if you have a drawing / sketch of the detail, it would be helpful.
