This is my first post here, so hi.
We have just switched (or rather supplemented) MX with C3D. And I am just getting my head around it. We have had a 3 day training course and it was a lot to take in, so I am just trying out a few things. I will probably end up posting quite a lot in the near future, so I do apologise
Anyway, first question:
I designed a very straight forward piece of road consisting of a centreline, 2 channels and a footway either side. I played around with superelevation, assemblies and created a corridor. This all works fine.
Now when I add a taper to my offset alignments (for instance to widen the carriageway at a junction approach in order to add a splitter island), I noticed that the corridor stays perpendicular to the centreline. So this means the 2m wide footway I specified is not actually 2m wide, measured perpendicular from the curb. (See attached)
I have figured out that I can achieve this by attaching an offset assembly to the curb and attach the footway sub-assembly to the offset assembly. (So the curb acts a bit like a subsidiary string in MX). However, in order to make this work, I need to assign the horizontal alignment and Profile of the offset alignment to the Offset in the Corridor Properties Parameters (see attached). So far I have only managed to do this by creating a temporary surface which is wider than the curbs, so I can apply a profile to the offset alignment.
This seems a bit of a silly work around for such a standard simple highway design principle. Is there an easier way to create footways that are not perpendicular to the centreline?
A few questions or suggestions:
Any help or suggestions are highly appreciated. Many thanks.....

Hi, I´m from Sweden.
Can you explain better how to solve the problem with perpendicular "offset". By using the alignment offset and not the assembley offset. Maybe you can post any pictures?
I have a road with a bus stop on the side. How can i solve it so the ditch is perpendicular to the widening?
I´m not familiar to the term "footway".
Thanks / Per
