Question
How can two PSC Box Girders placed on either side of a bridge alignment, each with individual superelevation, be modeled in CIM?
Answer
In brief, this can be handled by either assigning the super elevation reference point offset during the curve library assignment stage (ref: Method 1 in video) or directly at the time of creating main constraint paths (ref: Method 3 in video). Both methods result in the same modeling outcome but differ in workflow convenience.
The key steps involve:
- Creating constraint paths at required offset positions.
- Assigning super elevation vertex groups in the section definition.
- Applying reference point offsets either during library assignment or path creation.
