I have run into several cases where it would be useful to have a delta elevation option for a vertical type in linestring.
Example: - Building Footprint
- The front of the building is at an elevation that is to be determined
- The back of the building is 8 ft different because it is a walkout basement
This would allow the user to adjust the front elevation and have the rest of the line updated dynamically
There is also need for an inline delta elevation rule in the vertical design tool.
