Control points are the global positions of the target points, and are a sub-item of the Instrument Data folder. There can be only one set of control points for a project. There are two ways to manipulate Control Points: the Right-Click menu or the Control Point Editor.
Note: Several commands are available in both the Right-Click menu and in the Control Points Editor. A command in the Right-Click menu operate on all control points. The Control Points editor commands operate on only the selected Control Points. If no control points are selected the users is asked if they wish to perform the operation on all control points.
Edit | Launches the Control Point Editor |
Delete All | Deletes all Control Points. The user is prompted via a dialog box to confirm the deletion. |
Import | Launches the ASCII file import dialog box. |
Export | Launches the ASCII file export dialog box. |
Transform | Launches the Transform dialog box to allow the user to define a transformation sequence to apply to the control points. |
View | Launches the Scene creation dialog box to create a scene for viewing the control points. |
Draw | Draws the Control Points in CAD. The user is prompted via a dialog box for the layer to draw the Control Points on. |
To open the Control Point Editor, right-mouse click on Control Points under Instrument Data in the Current Project tree and then select Edit.
Along the top is a toolbar with several icons:
Activate Control Point toggles the selected control point(s) to be active in the current project. | |
Deactivate Control Point toggles the selected control point(s) to be inactive in the current project. | |
New Control Point brings up a dialog that allows users to specify the properties of a new control point to add. | |
Edit Control Points brings up the point edit dialog which allows users to change properties of the currently selected Control Point. | |
Copy Control Points allows users to copy the currently selected Control points to another point set (such as from the control points to the target points of a scan). | |
Delete Control Points deletes the currently selected control points. | |
Import Control Points brings up the ASCII file import dialog. | |
Export Control Points brings up the ASCII file export dialog. | |
Transform Control Points allows users to define a transformation sequence to apply to the control points. | |
View Control Points brings up the scene creation dialog to create a scene for viewing the current control point set. | |
Coordinate System allows users to choose the coordinate system the positions values are in (Global or any of the current scan positions) | |
Settings allow users to configure what properties of the control points are visible in the spreadsheet control. | |
Help brings up help documentation. |
Name will specify a unique name to be used for the Control Point in the Project.
X, Y and Z are the coordinates of the Control Point.
Description allows users to add information that describes the new Control Point.
Target Points allows the user to specify Target Points from any Scan to be referenced to the new Control Point.
Adds a new reference Target Point. Allows the user to edit the selected reference Target Point Deletes the selected reference Target Point
Clicking the Import button opens the Import Control
Points window. Navigate to the correct file and click
Open.
Currently supported file import types are TXT, CSV,
CRD and CRDB.
Once the file has been opened, the Import Control Points
dialog will display.
Clicking the Export Points button will open the Export
Control Points window, which allows users to export the data to
several different file formats.
In the Columns panel, click on the check boxes to include or
exclude the data elements. To change the order of the data elements
in the file, click on the element and then click the up or down
arrows to adjust its position.
The File panel determines which file format to
export to and also allows you to specify an extension other than
the default for a given file format.
The Text panel contains options when exporting to
the different text file types, ANSI Text or Unicode
Text. The Delimiter Type determines the
divider between data elements in the file. The Write
header option specifies whether to write a header line to
the file detailing the data ordering of the file.
Microsoft Excel allows the user to define the name of the
Excel worksheet that the points will be exported to. Note:
only available when exporting as Format: Microsoft
Excel.
XML allows users to define the Root and
Collection values and choose to Format data.
Note: only available when exporting as
Format:XML.
GCP - when exporting as GCP, click on the
Set button to choose the Coordinate Projection. Users can
choose to select a Pre-Defined projection, add a projection from a
file or create a User-Defined projection on the fly. Click
OK to select and return to the previous window. Users can
select to export the coordinates in Latitude/Longitude format and
also to select the appropriate units; Metric, US Feet
or International Feet.
Users can select a preset export format by selecting it from the
Presets drop-down menu. To define a new preset, include or
exclude the desired data elements in the Columns panel,

be added to the drop-down menu for future use.
To delete a preset, select it from the Presets drop-down
menu and then click the Green Dash button next to the

The Transform button opens the Transform Coordinate Points window where users can define a selection of transformation parameters to apply to the selected Coordinate Points.
Initially, the dialog will have no transformations specified. To
add a transformation, press the Green Plus button. which
will open the New Tranformationwindow.
Use the Type drop-down menu to select one of the four
Transformation types:
Translate allows the user to define a translation of the current data set by specifying offsets in X, Y and Z.
Rotations allow the user to rotate the current selection set by specifying rotations around the X Y and Z axis.
Scaling allows the user to scale the current selection by a set Factor in the X, Y and Z axis.
Advanced allows the user to specify a transformation matrix to be applied to the data.
After clicking the check button, users will be taken back to the
Transform Control Points window. From here users can add
more transformations, modify the currently selected one by pressing
the Green i button, delete them by pressing the
Red X button, or change their order of
application to the data using the Green arrow buttons. Press
the Green Tick button to apply the transformations.
