Side slope not matching up

Where is the mismatch? If it is the junction area, does the civil cell used (assuming a civil cell) have the same slope conditions as the main template? Does the main road have superelevation that could amend the hard shoulder slope, which in turn is not followed by the civil cell?

Do the templates match up? If there is a narrower shoulder (for example) in one of the templates, the slope to the existing ground will be closer to the road.

There are so many variations that could account for a mismatched side slope - all I would say is that if the templates are the same, there would / should not be any mismatch.

Please take a look at attach .dgn.  I use the same template to create a basic T civil cell.  Looks like it match the transition slope but not where it intersect.

I think the problem is that along the main road, your template drop is (say) every 20m - so the main road finds the ground at points 20m apart, and joins them with a striaght line.

Your junction template is finding a point almost halfway between the two points found by the main road template. The existing ground could have a small hill at this position - which will be missed by the main road templates - which is picked up by the civil cell.

The simplest method to get the two to match up more accurately is to make your main road template drops a smaller value - say 5m. Another option would be to add a special chainage (key station) drop at the end of the junction arc to the main road to get a template added at that position to see the effect.

Good job sir. Thank you.
