To fillet (round) corners in 2D geometry objects, in the Geometry toolbar, click Fillet (). You can also right-click the Geometry node and add this node from the context menu. Then enter the properties of the fillet operation using the following sections:

Select the points (vertices) that you want to fillet in the Graphics window. They then appear in the Vertices to fillet list. If the geometry sequence includes user-defined selections above the Fillet node, choose Manual to select points, or choose one of the selection nodes from the list next to Vertices to fillet.

Click the Active button to toggle between turning ON and OFF the Vertices to fillet selections.

Enter the Radius of the circular fillet arc.

Select the Resulting objects selection check box to create predefined selections (for all levels — objects, domains, boundaries, edges, and points — that are applicable) in subsequent nodes in the geometry sequence. To also make all or one of the types of resulting entities (domains, boundaries, edges, and points) that the resulting objects consist of available as selections in all applicable selection lists (in physics and materials settings, for example), choose an option from the Show in physics (Show in instances if in a geometry part; Show in 3D in a plane geometry under a work plane in a 3D component) list: All levels, Domain selection, Boundary selection, or Point selection. The default is Domain selection, which is suitable for use with materials and physics defined in domains. For use with a boundary condition, for example, choose Boundary selection. These selections do not appear as separate selection nodes in the model tree. Select Off to not make any selection available outside of the geometry sequence. From the Color list, choose a color for highlighting the resulting objects selection. See Selection Colors.

If you want to make the resulting entities contribute to a cumulative selection, select a cumulative selection from the Contribute to list (the default, None, gives no contribution), or click the New button to create a new cumulative selection (see Cumulative Selections).
