About the Boundary Blend Tool in Sheetmetal Design
Use the Boundary Blend tool to create a sheet metal wall or surface with boundary blend geometry. Create or reference an entity to define the surface or wall in one or two directions. The first and last entity in each direction define the surface or wall boundaries. You can define more fully the shape of the boundary blend geometry by adding more reference entities, such as control points and boundary conditions.
You can redefine a boundary blend wall as a surface, or a boundary blend surface as a wall, if the wall is not the first one in a design. You must specify thickness for a first wall. Keep in mind the following points when creating boundary blend geometry:
Curves, wall edges, datum points, and ends of curves or edges can be used as reference entities.
Reference entities must be selected in consecutive order but can be reordered.
For boundary blend surfaces defined in two directions, the outer boundaries must intersect to form a closed loop. Any excess segments are automatically trimmed.
