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, in the
Geometry toolbar, from the
Boolean and Partitions (
) menu, select
Partition Edges. You can also right-click the
Geometry node to add this from the
Boolean and Partitions submenu. Then enter the properties of the partitioning operation using the following sections:
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.
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. From the
Color list, choose a color for highlighting the resulting objects selection. See
Selection Colors.
From the Construction geometry list choose
On to make the resulting objects available only in the feature’s geometry sequence. The default option
Inherit means that the resulting objects become construction geometry if all input objects are construction geometry. Choose
Off to never output construction geometry objects. For more information, see
Construction Geometry.
