# Sphere3D

The Sphere3D function allows you to create a fixtured 3D sphere in the point cloud. It returns a Sphere3D structure containing the settings of the fixtured sphere.

# Sphere3D Inputs

The Sphere3D function has the following syntax:

Sphere3D(PointCloud,Fixture3D,ExternalFixture,Sphere3D,Show)

Parameter | Description
PointCloud | Reference to a cell containing a point cloud. The default value is $A$0.
Fixture3D | Specifies the point cloud coordinate system in which the 3D fixture is defined. It is offset from the PointCloud origin in the following format with the following arguments: {X, Y, Z, Rotation, Tilt, TiltDirection}
X | Offset on the X-axis from the PointCloud origin.
Y | Offset on the Y-axis from the PointCloud origin.
Z | Offset on the Z-axis from the PointCloud origin.
Rotation | Specifies the in-plane rotation in degrees around the PointCloud Z-axis. The value range is -180 to 180. The tool normalizes external references with values outside the allowed range to the allowed range.
Tilt | Specifies the tilt angle in degrees from the PointCloud Z-axis after rotation. The value range is 0-180. External references with values outside the allowed range result in an error.
Tilt Direction | Specifies the direction of tilt in degrees from the rotated PointCloud X-axis of the tool, around the PointCloud Z-axis of the tool. The value range is -180 to 180. The tool normalizes external references with values outside the allowed range to the allowed range.
Note: The Fixture3D parameter is only available if you set External Fixture to 0.
External Fixture | Specifies a reference to a Fixture3D structure defined in another cell. The function uses the referenced cell as the fixture of the function. Set to 0 (OFF) to use the internal fixture of the function instead.
Sphere3D | Specifies the radius and location of the 3D sphere. It is offset from the Fixture3D origin in the following format with the following arguments: {Radius, X, Y, Z}
Radius | The radius of the 3D sphere. The value range is 0.001 to inf.
X | Offset of the center point of the 3D sphere on the X-axis from the Fixture3D origin. The value range is -inf. to inf.
Y | Offset of the center point of the 3D sphere on the Y-axis from the Fixture3D origin. The value range is -inf. to inf.
Z | Offset of the center point of the 3D sphere on the Z-axis from the Fixture3D origin. The value range is -inf. to inf.
Show | Selects the type of graphics to overlay on the image.
0 = hide all (default) | All graphics will be hidden, except when the cell containing the function is highlighted in the spreadsheet.
2 = input graphics only | The input data will be displayed at all times.

# Sphere3D Outputs

Returns | A Sphere3D structure containing the parameters of the configured sphere, or #ERR if any parameter has been configured incorrectly.
Results | When initially inserted into a cell, the following functions are automatically inserted into the spreadsheet to create a result table.
| Radius | X | Y | Z
❒Sphere3D | GetRadius(Sphere3D) | GetX(Sphere3D) | GetY(Sphere3D) | GetZ(Sphere3D)

## Sphere3D Data Access Functions

The following 3D Data Access functions are automatically inserted into the spreadsheet to create the result table:

Function | Description
GetRadius(Sphere3D) | Returns the radius of the sphere.
GetX(Sphere3D) | Returns the X-axis coordinate of the sphere's center point.
GetY(Sphere3D) | Returns the Y-axis coordinate of the sphere's center point.
GetZ(Sphere3D) | Returns the Z-axis coordinate of the sphere's center point.
