Rectangle Primitive dialog box (SST)

Common options

Option	Description
Element Type	Lists the supported 2D element types.
Destination Collector
Mesh Collector	Lets you select an existing collector. Click New Collector to use the Mesh Collector dialog box to create additional mesh collectors. See Mesh collectors for more information.
Definition
By	Controls the definition method:Parameters: Lets you define the rectangle by assigning values to parameters in relation to the coordinate system you specify.Points: Lets you define the rectangle by locating points in space in terms of 3D coordinates.
Mesh Density
Along X	Defines the number of elements along the edge of the rectangle defined by Origin and X extent. The element sequence starts from Origin. When the software finishes meshing that edge, it moves along the edge between Origin and Y extent and generates the next layer of elements.
Along Y	Defines the number of elements along the edge of the rectangle defined by Origin (1) and Y extent (1). The number of elements you specify here define the number of layers in the mesh.
Top side points towards – Z	Select the check box to reverse the direction of the surface normals of the 2D elements so that they point towards the – Z direction.

Rectangle primitive defined by parameters

Option	Description
Definition
Coordinate System	Lets you create or select a coordinate system. The software uses the origin of the coordinate system as the origin of the primitive.See CSYS dialog box for more information.
Minimum X	Defines the starting position for the rectangle primitive along the X-axis as a distance measured from the origin of the specified Coordinate System.
Maximum X	Defines the terminating position for the rectangle primitive along the X-axis as a distance measured from the origin of the specified Coordinate System.
Minimum Y	Defines the starting position for the rectangle primitive along the Y-axis as a distance measured from the origin of the specified Coordinate System.
Maximum Y	Defines the terminating position for the rectangle primitive along the Y-axis as a distance measured from the origin of the specified Coordinate System.
Offset in Z	Defines an offset for the rectangle primitive along the Z-axis as a distance from the origin. The base section of the rectangle is always parallel to the X-Y plane.

Parameter	Definition
	Minimum X
	Maximum X
	Minimum Y
	Maximum Y
	Offset in Z (not pictured)

Rectangle primitive defined by points

Option	Description
Definition
Origin	Lets you select or create a point to define as the first point for the rectangle.Click Point Constructor to use the Point dialog box to create a new point. See Point dialog box for more information.
X extent	Lets you select or create a point to orient the X-axis and specify the length of the rectangle along the X-axis.Note: The order in which you select the points influences the order in which the software creates and orients the elements. The elements' front side is determined by the right hand rule.
Y extent	Lets you select or create a point to orient the Y-axis and specify the length of the rectangle along the Y-axis.Note: The order in which you select the points influences the order in which the software creates and orients the elements.

Parameter	Definition
	Origin
	X extent
	Y extent
