Boundary Patch
- Boundary
- Specifies the boundary of the patch. Select a chain of tangent continuous edges to specify a closed region. Once the boundary selection represents a closed region, you can select the next boundary.
- Condition
- Lists the name for the selected edge and the number of edges in the selection set. It also specifies the edge condition to apply to each edge of the boundary patch. Click the arrow to select an edge condition. Note: Because continuous edges must have the same edge condition, all selected surface edges that are tangent or continuous with the previous item are merged.
Contact (G0) 
Tangent (G1) 
Smooth (G2)
Note: You cannot apply tangent (G1) or smooth (G2) boundary conditions to selected sketches or edges that have two adjacent faces.
The selected edge in the following image is an example of geometry that does not support alternate boundary conditions.
