This change applies to the Surfaces > Rolled Edge > Tubular Offset tool, Surfaces > Surface Fillet tool, and Surfaces > Fillet Flange tool when Surface Type is set to Multiple Surfaces.
When Surface Type is set to Multiple Surfaces, the offset curves-on-surface are now segmented to correspond to the multiple tube surface boundaries. (When Bezier Surfaces is off, these also correspond to the input curves-on-surface, or surface edges.)
Fillet Surface and Fillet Flange
When Surface Type is set to Multiple surfaces (with Trim Type set to Curves on Surface for Fillet Surface and Auto Trim turned off for Fillet Flange) the curves-on-surface created at the edges of the fillets are now segmented to correspond to the multiple fillet surfaces. (When Bezier Surfaces is off, these also correspond to the boundaries of the input surfaces.)
