Why are you designing the assemblies from centerline out to the edge of the typical section? Isn't it best to build out to the edge of pavement and address all the variables with assemblies at the edges of pavement?
@@KyleEvansCivil Right but the super can be applied to the lane assembly. Just sharing a workflow that reduces the number of assemblies. If we build everything out from centerline there has be assemblies and regions for every place where the left and right edges differ from each other. If instead we model the lanes and add edges independently it becomes a much simpler model. I thought I saw ATG had a video about that technique.
@@KyleEvansCivil I can't find it offhand. It may have been by someone else. I can send an example if you like. If you have edge of travel way alignments or extracted featurelines, You can add them as baselines and apply assemblies to them for independent edge treatments. This is how it is done in Bentley software. The corridor then becomes a single assembly and region for the lanes and the edge baselines for the edges. Changing from curb to curb and sidewalk or ditch or a seamline for grading is simply a matter of splitting the edge regions and swapping the assemblies.

Most roads are based on a centerline kind of construction. Any SuperElevation is usually a rotation about the centerline.

@Neil Wilson Can you find that video and I can take a look at it? I cannot visualize how that would be easier.
