The Partition Edges node () provides an operation that partitions selected edges at specified locations. You can specify the positions by entering parameters based on the arc length or by selecting existing vertices whose orthogonal projections on the edges specify the positions. A Partition Edges node can occur at any position in the geometry sequence; it works with output geometries before the Form Union/Assembly node, assembly geometries, and virtual geometries. To add it to a 2D or 3D geometry, on the Geometry toolbar Boolean and Partitions () menu, select Partition Edges. You can also right-click the Geometry node to add this from the Boolean and Partitions submenu.

In the Edges to partition list, add the edges that you want to partition. If you select multiple edges and multiple vertices, then the number of edges and the number of vertices must be the same.

Specify the positions of the vertices used to project for the edge partitioning. From the Type of specification list, choose Arc length (the default) to add one or more parameters for the edge partitioning in the Relative arc length parameters list. The relative arc length parameters are scalar values between 0 and 1, providing relative arc length values of each edge that define the location of the partitioning vertices. Alternatively, choose Vertex projection to add vertices to the Vertices to project list. Then each edge for which the orthogonal projection of the vertex occurs in the interior is partitioned at the projection.

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).

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 if in a work plane’s plane geometry) 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.
