Combine

Combine two or more surface objects, that share at least one coincident edge, into a single surface object.

1. Combine has three distinct use cases:
   • Combine two or more different objects such as a curve and a surface into a single object. This case is purely for the convenience of grouping objects. However, this differs from the traditional operation of creating a group (ALT+G) in that, the combine object is a single entity, not a folder containing objects.
   • Combine two or more similar objects such two curves or two surfaces into a single object. This case is useful when you want to perform a single operation on a set of curves or surfaces.
   • Combine surfaces that share coincident edges, thereby effectively stitching them into a solid.
     Note: This is a rare case where the input surfaces must be at least position continuous forming a closed geometry. To verify if combine created a solid, use the Tolerance checktool under Analysis.
