Use the Edit Object () feature to adjust the edges and vertices for a 2D geometry object or to add or delete edges and vertices in the object. To edit a 2D object using the Settings window, in the Model Builder, right-click the Geometry node and select Edit Object from the context menu. To edit a 2D object using the Graphics window, select the object and click the Edit Object button. See Editing 2D Geometry Objects.

Select the Input object to edit in the Graphics window (any applicable geometry object or selection). When selected, a copy is made of the input object, and changes then operate on this copy. Changes made in the Input object after the copy has been made has no effect on the Edit Object feature. For this reason, it is not possible to change the Input object after it has been selected.

Click the Active button to toggle between turning ON and OFF the Input object selections.

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

In the Graphics window, select and add the Edge to edit (or use The Selection List Window). The parameters for the current edge are displayed in the table for x (m), y (m), (xw (m), yw (m) in work planes) — where the m in parentheses indicates the current geometry length unit; in this case the default unit: meter — and Weights, and under the table for the Degree list and the Start vertex and End vertex fields.

If required, click New to create a new edge. The new edge is linear, not connected to any other edges or vertices, and has both the start and the end coordinates set to 0. Click Delete to delete the current edge. Deleting an edge also deletes its adjacent vertices, if these vertices are not connected to other edges.

Click in the table cells to edit the x (m), y (m), (xw (m), yw (m) in work planes) and Weights and modify the control points of the edge. If the x or y value for the first or last control point is modified, any adjacent edges and vertices are automatically updated with the same value.

Select the Degree — Linear, Quadratic, or Cubic — to change the degree of the edge. When decreasing the degree, the control points are recalculated so as to approximate the old shape of the edge.

Under Start vertex, click the Active button to move the starting point of the edge to a different vertex. In the Graphics window, select and add the Edge. Under End vertex, click the Active button to move the endpoint of the edge to a different vertex. In the Graphics window, select and add the Edge. If required, click Disconnect to disconnect the start or end vertex of an edge from the rest of the object. A new vertex is created with coordinates matching the start or endpoint of the edge. This vertex can be moved without affecting the other edges that were previously connected to this edge.

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

In the Graphics window, select and add the Vertex (node) to edit (or use The Selection List Window). The parameters for the current vertex are displayed in the x and y fields under Coordinates, and the vertex is highlighted in the Graphics window.

Under Coordinates edit the x and y fields as needed.

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).

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.
