Hi,
I have an urban type design project that has a lot variations in the cross section. I.e. parking lanes, turn lanes, through lanes, various width medians and footpaths etc.
I have started designing in 2D using the geometry tools, my next step is to take this model to 3D. Is there any training videos or wikis that go into the 3D non-corridor modelling in more detail?
I went away from the template model because I thought I would need to create too many different templates and transition between them, could I use templates for this instead of the geometry tools?
Any help appreciated.
Thanks
Nathan.
Hi Nathan, the answer comes a bit late but might be useful for others and for you in the future. There is a series of videos on the learn server on Non Corridor Modelling:

I understand. I have worked on several projects where I have switched back to the previously version. SS4 is difficult to work with at first, especially if you don't have the time.
I would like to add to the comment I originally wrote. I have been working on a fairly complicated project with multiple interchange ramp connections, walls, barriers etc... and using multiple corridors per alignment has made modeling much easier. Like I said in the previous post, setting up several corridors takes a little more effort at first , but after they are setup modifications are a lot simpler. For example, I have my end conditions in a separate corridor , so if I need to push the a wall back few hundred feet I can just modify that one corridor. Also seems to improve processing having the end condition corridors in a separate file from the pavement corridors. My pavement corridors don't need to target existing terrain, which saves processing time. If you were to advise someone on using this method, I would recommend breaking the corridors up into at least a pavement left & right and end condition left & right. I not saying this is the best or only way to model a project, but it is worth looking into.
Hi Zane, thanks for the reply, thought I would follow up, I ran out of time and ended up going back to MX Road input files for the final design model. But I did end up using corridors with point controls, and linear templates like you suggested for my paths etc. Seems to work fine, just need to think it all out beforehand, I ended up having to recreate multiple corridors etc.
I will continue to build the model in openroads when I get more time, I thnik my next step will involve creating and using civil cells for the intersections. I just didn't have the time to learn on the fly for this project.
Nathan,
There are several ways to handle a complex urban design. With SS2 I have always defaulted to using 3d breaklines for the final surfaces. Using corridors and InRoads surface design tools to create the 3d features , then creating the different surface models from these features. Corridors could do all this, but it can become very complicated when you are dealing with medians, approaches, pathways, walls etc....
Using OpenRoads geometry to create 3d features then surface templates may be an option. At least for the pavement areas. The workflow with the current tools we have can get very time consuming though. You have to create individual vertical geometry elements for every cross slope change, plus after complexing the elements together modifications can become difficult. I have stated in a few posts that it would be great to have an offset alignment tool like Civil 3d were we can control the station, offset and cross slope of a geometry feature along the whole alignment. Maybe someday :-)
One solution is using multiple corridors. The current project I am working on involves an interchange with multiple lanes, cross slopes, ramps, etc.. We are modeling the lanes and shoulders in separate corridors. The end conditions are also in separate corridors (or linear templates). It may seem like a lot of work but it actually works pretty well once you have everything built. We are using point controls linking the corridors together , so for example a change in the centerline profile will update all corridors. If you choose to use this method the best advice I can give you is separating the corridors into individual files then reference them together for the final model. Something to think about.
