Composite Curve
A Composite Curve feature defines a 2D curve object having several edges of different types. It has a sequence of subnodes (child features) of the Polygon, Circular Arc, Interpolation Curve, Quadratic Bézier, and Cubic Bézier types. The child features always form a connected curve chain (open or closed). You can create a Composite Curve feature node () in the following ways:
•
Draw a sequence of curve segments in the Graphics window using the Polygon, Circular Arc, Interpolation Curve, Quadratic, and Cubic toolbar buttons in the Sketch toolbar.
•
Select a number of edges in the Graphics window and click the Composite Curves toolbar button () in the Sketch toolbar.
•
Select a number of curve features in the model tree, right-click, and select Composite Curves from the context menu.
Object Type
By default, the Object type list is set to Curve. If you choose Solid from the Object type list, a closed composite curve will give a solid geometry object.
Selections of Resulting Entities
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 cone consists 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) list: All levels, Domain selection, Boundary selection, Edge 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.
Cumulative Selection
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).
Assigned Attributes
Select the Construction geometry check box to make the resulting objects available only in the feature’s geometry sequence. For more information, see Construction Geometry.
