In Offset Chain, the user interface logic is enhanced in several ways for better reference handling and feature workflows:
1. When changing the offset chain/curve, the reference surface collector is auto-populated. If the previously selected surface reference is still valid, it takes priority and will no longer be overwritten. This applies to the 
Along Surface and 
Normal to Surface options and is also enabled for external references chains in assemblies.

◦ The selected chain does not lie on the quilt or body containing the surface (when the Along Surface offset option is used)
Along Surface offset option is used)◦ The selected curve does not lie on the reference surface (when the Normal to Surface offset option is used)
Normal to Surface offset option is used)The reference surface status is indicated more visibly with a red or yellow dot in the collector and in a What's wrong message.

Previously, surface references might have gotten overwritten inadvertently when selecting new chain references.
Benefits
Increased usability through better reference handling, and guidance in the user interface
