Hello
I have attached an image, in which you will (hopefully) be able to see some wireframe cross sections of some timber floor joists.
(it's a 2D wireframe referenced in to a 3D model). As you can see, each cross section through the joists is indicated/emphasised with a 'cross'.
How does this get dealt with in BA, when generating a 2D cross section with a DV. As far as I know this type of 'graphic symbol/representation' is pretty much standard (certainly here in the UK IMHO)
It would not seem possible to set/create this 'effect' via the Dataset.
