Result Topology of Face Blend

The Face Blend operation can be stored in the model structure in several topological variations. The choice of a topological solution is combined with the walls-trimming. Following result topology options are available:

Separate Body
Neither wall will be trimmed and the blend surface will stay as a standalone surface body. The objects selected for the walls to blend will remain in the model structure in the original state. The blend operation will be represented by a separate surface body – the blend surface.

Trim Walls
Both walls will be trimmed along the line of contact without attaching the blend to any wall. This solution has a practical meaning only for surface bodies. The model structure will reflect the face-face blend operation alone at the top level. The operations whose faces were selected as walls will be written in the model history one level deeper. Meanwhile, the blend operation will be represented by three surface bodies. This means that if, for instance, the operation Divide Solid is applied to the blend then three separate surface bodies will be created, the two trimmed walls and one blend surface.

In Left Walls
Both walls will be trimmed and the blend surface will be united with the walls. If blending was done between two different surface bodies then these bodies are united into one by the blend. The operation used as the left wall will further be used as the reference in the model structure.

Create New Body
Both walls will be trimmed and the blend surface will be united with the walls in a single solid body if possible. This solution can only be used together with the Faces to Wall trimming option. This option is similar to the previous. The specific of this option is the system attempting to create a solid body. This is done if a check is satisfied for the resulting geometry to form a closed volume.
