Parameters
- view View
- The view in which the dimension is to be visible.
- arc Arc
- The extension arc of the dimension.
- arcRef Reference
- Geometric reference of the arc to which the dimension is to be bound. This reference must be parallel to the extension arc.
- firstRef Reference
- The first geometric reference to which the dimension is to be bound. This reference must intersect the arcRef reference.
- secondRef Reference
- The second geometric reference to which the dimension is to be bound. This reference must intersect the arcRef reference.
