#### Connect.fuse\_face\_zonelets(part\_id, source\_face\_zonelet\_ids, target\_face\_zonelet\_ids, params)

Perform fuse between overlapping face zonelets within a single part. Surfaces that are fused can then be colocated, merged or removed as directed.

**Parameters:**

Id of the part.

**source\_face\_zonelet\_ids**

Ids of source face zonelets to be fused.

**target\_face\_zonelet\_ids**

Ids of target face zonelets to be fused.

**params**

Parameters for fuse operation.

**Returns:**

**[`FuseResults`](ansys.meshing.prime.FuseResults.md#ansys.meshing.prime.FuseResults)**

Returns the FuseResults.

**Return type:**

[`FuseResults`](ansys.meshing.prime.FuseResults.md#ansys.meshing.prime.FuseResults)
