Forum Post: RE: In Bentley Substation, is there a certain presentation style that will let me show my 3D objects (with hidden lines) that are referenced into my 2D plan drawing, while letting other line work show through the 3D elements as well?

Jeff, the suggestion is essentially to have the reference attached twice, one overlaid on top of the other, with different presentation styles set for each. The easiest way I thought to do that was to simply copy the reference so I could use a base point to make sure the copy was aligned with the original.
