The Object Point option allows you to query points and you will be asked to indicate the point with the graphic cursor. When a point is found, the DTM Point Properties Dialog Box as shown below is displayed. This dialog allows you to change any of the information attached to the point.
The Identification group displays the point’s code and number. Note that any comma codes attached to the point are not displayed here but can be viewed using the property sheet to the right of the dialog box.
The Coding button allows you to create or change the code defaults for the queried point. If a code prefix which matches the code cannot be found, you will be asked if you wish to create a new one. If you do, you will be asked to enter the prefix and description and then specify the code defaults for the new prefix. The Report button allows you to create a report window containing the attributes of the queried point.
To the right of the dialog is a property sheet whose pages display the various point attributes. When the dialog box is initially displayed, the Co-ordinates page is active. The Easting, Northing and Height fields display the co-ordinate values, the number of decimals used being controlled by the current display options. If you wish to change one, select the field and enter a new value.
If the Height field is empty, the queried point has not been given a level and is assumed to be 2D. If you wish to set a point to be 2D, highlight the value in the Height field by double-clicking it and press the backspace arrow. Note that if the point is used by the DTM triangles, you will not be allowed to set it to be 2D. Also, if you change any of the co-ordinates of the point, you are also changing the DTM triangles.

The Comma Codes page allows you to define which comma codes are used to adjust the shape of the features that use the point and is shown to the right. The function of each of the comma codes has been described in the chapter on point coding and will not be described here. Suffice to say that to activate any of the comma codes, with the exception of those in the Curving group, you need only tick the check button next to it. For those in the Curving group, select the radio next to the curving comma code that you require.
The Attributes page allows you change and enter any remarks and dimensions attached to a point. The Remarks field is a multi-line edit field and you are able to enter multiple lines of text. The Dimensions field is also a multi-line field allowing you to enter dimensions. Each dimensions should be on its own line in the normal format “dim=value”.
The Photos page allows you to view any photographs that have been attached to a point. The Image Files list shows the names of the files that have been attached and the Preview image shows the currently highlighted image in the list. The Add buttons allows you to add photographs to a point. You will need to select the image file using the standard open file dialog. The Remove button will remove the currently highlighted image from the list. If you double-click the name of an image in the list, n4ce will open the appropriate application that Windows is currently using to view the image in higher resolution, such as Windows Photo Viewer.
