__________ make it possible for Civil 3D objects and designs to be linked and shared between drawings.

• A. External References
• B. Data Shortcuts
• C. Worksets
• D. Shared Blocks

Answer: (B)

Data Shortcuts let Civil 3D objects live in one drawing and be referenced in others, so design data can be linked and reused across multiple drawings. By creating a data shortcut for an object (such as a surface, alignment, corridor, or point) you publish a pointer to that object rather than duplicating it. In other drawings, you can insert that shortcut to bring in the Civil 3D data while keeping the original object intact. This setup keeps objects consistent across drawings—updates to the source object propagate to all drawings that reference it without recreating geometry.

External References link entire drawings, not specific Civil 3D objects. Shared Blocks pertain to symbol reuse and don’t provide live ties to Civil 3D design data. Data Shortcuts are specifically designed for cross-drawing Civil 3D object sharing, which is why they’re the best fit here.
