# PointFromLines3D

The PointFromLines3D function is used to construct a 3D point from the nearest intersection of two Line3D structures as infinite lines. The constructed point is returned as a Point3D structure.

## PointFromLines3D Inputs

The PointFromLines3D function has the following syntax:

PointFromLines3D(PointCloud,Line3D0,ExternalLine0,Line3D1,ExternalLine1,Show)

See the table for a description of the available parameters.

Parameter | Description
PointCloud | Reference to a cell containing a point cloud. The default value is $A$0.
Line3D 0 | Specifies the offsets of the first 3D line structure to use for constructing the 3D point. It is offset from the PointCloud origin in the following format with the following arguments: {X0, Y0, Z0, X1, Y1, Z1}
X0 | Offset of the 3D line's starting point on the X-axis from the PointCloud origin.
Y0 | Offset of the 3D line's starting point on the Y-axis from the PointCloud origin.
Z0 | Offset of the 3D line's starting point on the Z-axis from the PointCloud origin.
X1 | Offset of the 3D line's ending point on the X-axis from the PointCloud origin.
Y1 | Offset of the 3D line's ending point on the Y-axis from the PointCloud origin.
Z1 | Offset of the 3D line's ending point on the Z-axis from the PointCloud origin.
Note: This parameter is available only if External Line 0 is set to 0.
External Line 0 | Specifies a reference to a Line3D structure defined in another cell to be used as the first line in constructing the 3D point. Set to 0 (OFF) to use the function's internal Line3D structure.
Line3D 1 | Specifies the offsets of the second 3D line structure to use for constructing the 3D point. It is offset from the PointCloud origin in the following format with the following arguments: {X0, Y0, Z0, X1, Y1, Z1}
X0 | Offset of the 3D line's starting point on the X-axis from the PointCloud origin.
Y0 | Offset of the 3D line's starting point on the Y-axis from the PointCloud origin.
Z0 | Offset of the 3D line's starting point on the Z-axis from the PointCloud origin.
X1 | Offset of the 3D line's ending point on the X-axis from the PointCloud origin.
Y1 | Offset of the 3D line's ending point on the Y-axis from the PointCloud origin.
Z1 | Offset of the 3D line's ending point on the Z-axis from the PointCloud origin.
Note: This parameter is available only if External Line 1 is set to 0.
External Line 1 | Specifies a reference to a Line3D structure defined in another cell to be used as the second line in constructing the 3D point. Set to 0 (OFF) to use the function's internal Line3D structure.
Show | Selects the type of graphics to overlay on the image.
0 = hide all (default) | All graphics are hidden, except when the cell containing the function is highlighted in the spreadsheet.
1 = result graphics only | The result graphics of the function are displayed at all times.
2 = input and result graphics | The region of interest, the input data and the results are displayed at all times.

## PointFromLines3D Outputs

Returns | A Point3D data structure containing the constructed 3D point, or #ERR if any of the input parameters are invalid.
Results | When initially inserted into a cell, the following functions are automatically inserted into the spreadsheet to create a result table.
| X | Y | Z
❒Point3D | GetX(Point3D) | GetY(Point3D) | GetZ(Point3D)

## PointFromLines3D Vision Data Access Functions

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

Function | Description
GetX(Point3D) | Returns the X-axis coordinate of the 3D point.
GetY(Point3D) | Returns the Y-axis coordinate of the 3D point.
GetZ(Point3D) | Returns the Z-axis coordinate of the 3D point.
