Description
The 
Part Fuse command fuses (unites) selected Part objects into one. This operation is fully parametric and the components can be modified and the result recomputed.
This command is an automated form of the 
Boolean Operation.
Usage
- Select two or more shapes
- There are several ways to invoke the command:
- Press the Fuse button.
- Select the Part → Boolean → Fuse option from the menu.
- Press the
Supported inputs
Input objects must be OpenCASCADE shapes. Examples: stuff made with Part, PartDesign, Sketcher workbenches. Not meshes (unless those were converted to shapes) - for meshes, there are specific Boolean commands in MeshDesign workbench.
- Solid + Solid: the result is a solid that occupies all the volume covered by the inputs
- Shell + Shell, Shell + Face, Face + Face: the result is a shell. Where faces intersect, they are split. Shells can be non-manifold. After fusion, faces can be united by Refining the result.
- Wire + Wire, Edge + Wire, Edge + Edge: the result is a wire. Edges are split where they intersect.
Compounds are supported; however, it is assumed that shapes packed into a compound do not touch or intersect. If they actually do, Fusion will likely fail, or produce an incorrect result.
Options
Items can be added and removed from a fusion, by dragging them in or out of the fusion feature in the Tree View with the mouse. To drag items out of a fusion you have to drop them onto the document node (the filename) of your model. A manual recompute (press F5 key or click on the 
Recompute icon) is required to see the results.
