To thicken 2D curve objects or edges in the normal direction and thereby convert them to 2D solid objects, in the Geometry toolbar (Work Plane toolbar when working in the plane geometry sequence of a work plane in 3D), Conversions menu click Thicken (). Then enter the properties of the thicken operation using the following sections:

From the Geometric entity level list, choose the level of the entities to thicken: Object or Boundary (that is, edges in 2D). Then select the objects or entities that you want to thicken in the Graphics window. The curve objects or edges appear in the Input entities list. If the geometry sequence includes user-defined selections above the Thicken node, choose Manual to select objects or entities, or choose one of the selection nodes from the list next to Input entities.

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

Select the Keep input objects check box to use the selected geometry objects for further geometry operations.

Select an Offset — Symmetric (the default) or Asymmetric.

If Symmetric is selected enter a Total thickness.

If Asymmetric is selected enter an Upside thickness and a Downside thickness.

For symmetric thickening of open ended curves select how the line segments at the ends of the thickened object are generated. From the Ends list choose Straight (default) to generate straight edges in the normal direction to the input edge, or choose Circular to generate circular arcs tangent to the offset edges.

When offsetting edges of convex corners the operation can create new edges by several methods to close the gap that would result otherwise. From the Convex corner handling list, choose Fillet (default) to add circular arcs that are tangent to both offset edges of convex corners, or choose one of the other available options:

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).

If you have Named Selections that include entities on the input objects, select the Propagate selections to resulting objects (selected by default) check box to update the selections to corresponding entities on the output objects, when possible. Clear the check box to not propagate the selection to the resulting objects. This can be useful in combination with selecting the Keep input objects check box so that the selections refer only to the input objects.

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.
