In this release the Coach Sweep envelope is not created correctly: the elevation offset is incorrectly applied.

Conversation here: https://communities.bentley.com/products/rail_design/f/openrail-forum/200842/coach-sweep

A possible workaround is described in this video:

1. create rails: don't use active profile but select the profile. It is to prevent rails to be updated when the active profile will change.
2. create a corridor to create track plane CL (3D rails used as point control)
   Don't use active profile but named profile. Same reason than above
3. project track plan CL profile on CL
4. set track plane CL as active profile for CL
5. calculate sweep path
6. copy sweep path to keep something with no rule
7. delete original sweep path
8. change back CL active profile to good one
