I have such memory too :)

It would, also need Visibility Envelopes too and ability to use Envelope in Design

I remember Bentley colleagues at an Australian Bentley Civil conference a few years ago mentioning the ultimate goal was "object" based sight visibility calcs that scanned all objects in the model the same way as earthworks quantities are now calculated.

That would be very powerful and a game changer if/when it happens...

Mark - the limitation of the way SSD tool work is that it allows to pick only one design surface so when you model barriers as separate corridors, you need to combine them with the proposed road surface. I would like to see SSD tool honoring all meshes that are in Default-3D model.

John - we model barriers as separate corridors rather than part of the road tempplate. Our barrier template contains a component for the working width which is used for clash detection but also to create the top mesh out of barrier corridor. Then, we combine the road top mesh and the barrier top mesh using the microstation stitch mesh tool and that forms the combined surface we use to run SSD. Hope it helps.

Other than modelling them fully in 3d, no I don't. Sorry.

I understand, thank you for you reply, do you know of any other methodologies to incorporate barriers into clash detection?

3D linestyles are just that - a line style. If you turn of the LineStyle View Attribute - the line will be shown as a line. 3D linestyles cannot be used for clash detection for the same reason.
