Hi All,
Have anyone tried GC Connect Edition to develop parametric 3D model for roads, Tunnels and Segment Bridge structures. If possible, please share some info.
Thanks,
Anjum
Anjum,
you need to be specific about what you want GC to do for you as we have Road and Bridge tools that are highly parametric already.

Hi Brenden,
Thanks for the reply.
As you know precast segments in tunnel and bridge structures are typical and follows a fixed pattern.
So, we want to use GC to model such precast segment components and later these elements can be placed in sequence to make tunnel or bridge by linking with the given alignment drawings or details.
after modelling the Tunnel or bridge model we want to automatically generate all the original coordinates of individual precast segments (which is normally done manually). These coordinates information would be useful to accurately cast the precast segment.
following similar study has been performed earlier using other tools

Please advice.
Thanks and Regards,
Hi Anjum,
In principle, this is very well possible in GC. The approach would entail the following:
(1) define the components that you want to place along an alignment; these could be Generated Node Types within GC, especially if specific behaviors are expected; AECOsim Building Designer's user-defined building components ("Objects"); or attributed cells;
(2) use the ReferenceAttachment node type to reference the road or rail alignment as generated in OpenRail, OpenRoads, or similar applications;
(3) move the ReferenceAttachment so that it is within the solids area of the active design file (GC's operation depends on that);
(4) set up a GC Range node around the alignment data in relation to which you want to place components;
(5) use an appropriate GC node type (e.g. PolyLine) to create GC nodes based on the alignment data;
(6) use an appropriate technique to place CoordinateSystem nodes along the alignment for placement of the components from (1);
(7) place the components.
Caveats:
Beyond that, your concrete work cases will provide better opportunity to provide help. If those work cases are confidential, please send them to Volker.Mueller (at) Bentley.com.

Hi Volker,
Thank you very much for highlighting us the approach and steps. We shall be following this approach to try first.
If on nearly similar approach, any on demand video has been uploaded ever on Bentley learn server, please share the links.
