When the Propagation property is set to Yes, the selected entities of a Named Selection are tracked through all modeling operations and the Named Selection feature is updated to reflect the modeling changes. For instance, when the selected entity is split, the Named selection feature will be updated to contain the new split entities. Some examples shown below explain the propagation behavior for different modeling operations.
Consider the following three scenarios:
Consider two frozen bodies as shown below for Cases 1, 2 and 3. Named Selection A is created for the upper box face and Named Selection B for the cylindrical face.
 |  |
Case 1
After Boolean Unite between box and the cylinder, Named Selection A contains the face which are created by splitting of parent face. Named Selection B retains remaining portion of the cylindrical face after Boolean unite operation. The results are shown below.
 |  |
Case 2
After Boolean subtract with box as the target body, Named Selection A contains the face entities which are created by splitting of parent face. Named Selection B tracks the newly created cylindrical face after Boolean subtract operation which is derived from original cylindrical tool body.
 |  |
Case 3
After slicing both box and cylinder with the upper face surface of the box, Named selection A will have three faces getting tracked, which are created by splitting the parent face. Named Selection B will have two cylindrical faces tracked as shown in the figure below.
 |  |
Named Selection A is created for upper box face (left side). If box is copied using Pattern or Body Operation feature, Named Selection propagates to copied bodies.
Named Selection A is created for the middle upper face of the box (left). When the upper middle face of the box is merged with the two adjacent faces, Named Selection A will have the entire top face of the box.
Usage with features — Named Selection Propagation is not be available for the following Ansys DesignModeler features:
Simplify (DesignModeler Electronics-related)
Slice (when Slice Off Edges option is selected)
Named Selection Propagation is not supported for Line Bodies in Ansys DesignModeler.
