NIYA, I don't think there's a way to display dimensions. Hello, CSI! Please add this capability to SAP. Even ETABS' klutzy dimensioning would be welcome. You might try exporting your model to DXF to view dimensions, but that would be extra effort.
You can draw a "None" null frame element with snap to joint activated in order to view distances between any two point, but again, that's a little lame. A "distance calculator" tool between two points is needed.
