About Chains in Style
You can use one-by-one or rule-based edge chains as references in the
Surface and
Curve from Datum tools.
• For the Surface tool, the chain segments require tangent continuity or greater. They can be part of the current Style feature, or they can be external Style curve segments.
• For the Curve from Datum tool, the chain segments require position continuity or greater.
When you create a surface, or when you align two surfaces using the Surface Edit tool, you can adjust the edge chain length in the following ways:
• Drag the drag handles.
• Snap to a reference.
• Specify a measurement.
You can also reorder the chains in a surface without deselecting them.
