Part Union

Description
The tool unites (fuses) selected Part objects into one. This operation is fully parametric and the components can be modified and the result recomputed.

This command allows you to perform quickly this Boolean operation.

Usage

 * 1) Select two or more shapes
 * 2) Press the  button.

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 tools 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 the fusion, by dragging them in or out of the fusion feature in the tree view with the mouse. A manual recompute (press F5 key or click on the recompute icon) is required to see the results.

After this operation it may be necessary to clean the shape with RefineShape.
