Create separate faces

The Fluid Volume tool automatically merges tangent or smooth faces, so the surface cap for a hole can become part of the surrounding face.

The Split Result option creates separate faces in the volume for each surface in the model. A typical use for split faces is to simplify geometry in a hydraulic manifold.

In the image below, a cylindrical extrusion covers the holes where each port intersects the main passage. A work plane at the end of manifold removes the fitting from the interior volume. By default, the interior volume is a simple cylinder. Split Result creates a separate face for each intersection of a port and the main passage.
