I am in the process of modeling curb ramps with 3D linework. I am generating horizontal alignments to define the general geometry of the ramps in 2D and then adding profiles to these lines to generate 3D linework. In my 2D view, the 3D and 2D linework do not correspond. At first I thought this was to be expected due to what was described here: https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/9991/3d-alignment-location-different-than-2d-alignment. However I've noticed the offsets getting larger and it is resulting in my terrain models I'm generating having a lot of issues of overlaps. I've attached my dgn for reference. I've noticed that the linework is "fixed" if I change the linear stroking tolerance value of the linear element to something different (higher or lower) than the original value. I'm hesitant to accept this as a fix because there are a lot of lines I would manual need to change with this approach and I'm not confident it is a long term fix to the issue I'm experiencing.

I cannot reproduce. In this file I've drawn horizontal geometry, created profile and set as active, then tentative snapped on the beginning and ends of alignment in both views. The coordinates matched up. How are you determining this is an issue? Screen shots with description would help.

Marcus,
I just reproduced the issue in the dgn file I provided. I made a simple horizontal line 2' long and added a simple vertical profile 1' long from sta 0+00 and this is the result. I agree with you that the coordinates match up exactly across the 2D and 3D models, but there is a distinct graphic misrepresentation occurring in my 2D view when displaying 3D model reference. The first screen shot shows the 2D model view (view 1) with the 2D horizontal alignment in blue and the 3D model reference in white and view 4 shows the analysis tool relationship of the linework with respect to the active profile. As you can see there is an graphical offset occurring that I would not expect to see. The blue and white line should correspond along the length of the profile.
A similar issue is occurring in my 3D view with respect to my terrain model I created and the 3D linework that defines this boundary. Also you can see in my 3D model view my cursor is hovering over the 3D line, and the selected linework highlight this line in a similar distance offset from where it is shown in the view. Also the 3D linework and terrain model breakline/triangle don't correspond.
I notice that the 3D referenced model has an offset value. This is the reason for the discrepency.
Can you create a new dgn from seed with the same results?
I tried to reproduce the result with a seed without any luck so it seems to be a local issue to this file at this point. I think you are on to something with respect to the 3D referenced model having an offset value, however why would changing the stroking value for the properties of the feature line cause the 2D model and 3D model linework to line up for that individual line despite the offset value with respect to the 3D reference model?
