# PlotExternalRegion3D

The PlotExternalRegion3D function allows you to draw a Region3D structure by referencing an existing 3D region such as a Region3D, Box3D, Cylinder3D,Plane3D, or MultiBoxRegion3D configured in another spreadsheet cell.

The PlotExternalRegion3D function returns a Plot structure containing the settings of the drawn Region3D.

# PlotExternalRegion3D Inputs

The PlotExternalRegion3D function has the following syntax:

PlotExternalRegion3D(PointCloud,ExternalRegion,Color,Transparency,ShowAxisIndicator,ShowDirectionIndicator,DirectionIndicatorAxis,ModelMode,LineDrawingThickness,Show)

Parameter | Description
PointCloud | Reference to a cell containing a point cloud. The default value is $A$0.
External Region | Specifies a reference to a 3D region defined in another cell of the spreadsheet to be used for plotting the Region3D structure. Note: Leaving this setting on 0 (OFF) results in the function returning an error once set up.
Color | Specifies the color of the wireframe or surface, depending on the selected Model Mode. The default value is Lime Green. Note: If the Model Mode parameter is set to Solid with Wireframe, then the wireframe will be drawn in black regardless of the value of this setting.
Transparency | Specifies the transparency of the drawn structure or its elements, depending on the selected Model Mode. The value range of the property is 0 – 100 (from no transparency to complete transparency), and the default value is 0 (meaning no transparency).
Show Axis Indicator | Shows the axis indicator for the plotted structure. This parameter is disabled by default. Note: This parameter is only available if the External Region parameter points to a Box3D structure.
Show Direction Indicator | Shows the direction indicator on the axis selected with the Direction Indicator Axis parameter. This parameter is disabled by default. Note: This parameter is only available if the External Region parameter points to a Box3D structure.
Direction Indicator Axis | Specifies which axis to show the direction of with the Direction Indicator. By default, the X-axis direction is indicated. Note: This parameter is only available if the External Region parameter points to a Box3D structure.
Model Mode | Specifies how the region is drawn in the point cloud: Points: Only the corner points of the region are drawn. Wireframe: The region is drawn as a wireframe only, its surfaces being completely transparent. This is the default setting. Solid: The region is drawn with its surfaces being completely solid. Solid with Wireframe: The region is drawn with solid surfaces, with its wireframe toned in black color.
Line Drawing Thickness | Specifies the thickness of the wireframe lines. This setting is available only if the Model Mode parameter is set to Wireframe or Solid with Wireframe, and its default value is 5 with a range between 1 to 10.
Show | Selects the display mode.
0 (Unchecked) = Off | The structure will be hidden, except when the cell containing the function is highlighted in the spreadsheet.
1 (Checked) = On (default) | The structure will be displayed at all times.

# PlotExternalRegion3D Outputs

Returns | A Plot structure that allows you to modify the plotted 3D region.
Results | When inserted into a cell, a ❒Plot structure is created, containing the settings of the 3D region drawn in the point cloud when the job is Online.
