A line segment is a line between a starting point or vertex and endpoint or vertex in 2D and 3D. In 2D, add a Line Segment node (
) by right-clicking the
Geometry node and select it from the context menu in 2D or from the
More Primitives submenu in 3D., In the
Geometry ribbon, you can choose
Line Segment from the
Primitives menu in 2D and the
More Primitives menu in 3D.
Define the starting point for the line segment. From the Specify list, choose
Vertex (the default) to specify a start vertex by selecting a vertex from the geometry or using an applicable selection in the
Start vertex list. Click the
Active button to toggle between turning ON and OFF the start vertex selection. Alternatively, select
Coordinates to specify the
x,
y, and (3D only)
z coordinates for the starting point.
Define the endpoint for the line segment. From the Specify list, choose
Vertex (the default) to specify an end vertex by selecting a vertex from the geometry or using an applicable selection in the
End vertex list. Click the
Active button to toggle between turning ON and OFF the end vertex selection. Alternatively, select
Coordinates to specify the
x,
y, and (3D only)
z coordinates for the endpoint.
The coordinate system in which the coordinates above are interpreted (in 3D only, and if at least one of the Specify lists is set to
Coordinates). From the
Work plane list, select
xy-plane (the default, for a standard global Cartesian coordinate system) or select any work plane defined above this node in the geometry sequence. If you choose a work plane, the work plane and its coordinate system appear in the Graphics window, using an extra coordinate triad with the directions
xw,
yw, and
zw (which are then used to specify the line’s position).
Select the Resulting objects selection check box to create predefined selections (for all levels — objects, domains, and boundaries — that are applicable) in subsequent nodes in the geometry sequence. To also make all or one of the types of resulting entities (domains and boundaries) that the interval 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,
Boundary selection (2D or
Edge selection (3D), or
Point selection. The default is
Boundary selection (2D) or
Edge selection (3D). 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.
