The Display of Points

The first page of the code prefix property sheet is called Point and an example of this is shown below.  The fields in the page allow you to define how the position for each point on a feature using the current code prefix will be displayed.

The Enabled check button is disabled for this item.  For query purposes, a point is always expected to be displayed.  If you do not want a point, there is a point style called None which performs this task.

Layer Styles and Pen

The Layer, Pen and Point Style fields define the graphical attributes that n4ce will use.  The Point Size field defines the size of the point in millimetres at the view or plot scale.  In the example above, 2mm displayed at a scale of 1:500 will display a point that, in real world size, is 1m across.

Model Points

The Model Points check button allows you to specify whether any point using this code prefix is to be used in any DTM triangles.  There are situations where the object being displayed is either above or below the ground surface and would have a detrimental effect on the model.  Examples of this are overhead wires, underground services and the eaves of buildings.

Time and Date Dimensions 

The Time and Date Dimensions checkbox specifies where these two dimensions will be created from the timestamp of observations or points when creating a model. However, this checkbox only enables that specific Point to have Time and Date attributes connected and doesn't allow it to be shown until the Model has been created. This window can be reached when we right click Models and select new.

Align Point to Feature

The Align Point to Feature checkbox enables you to specify the alignment of points on specifically coded features as seen with the coded feature (KB) below:

            Feature with aligned points                                          Feature without aligned points

Do Not Upload

The Do Not Upload checkbox will restrict the code(s) you have created from being opened in other programs or saved in alternative formats to allow exporting the data to other software.

Point is Control

The Point is Control checkbox is for the data that is imported into ⁿ4CE. If the code used for the point has Point in Control enabled, ⁿ4ce will utilise this as a Control Station co-ordinate instead of a standard detail co-ordinate.

Comma Codes for the Point Style

The No Point comma code, fixed to 0, is used when you wish to turn off the display of any point marker.  The automatic addition of this comma code is an option when using some of the feature editing tools in the model.  The Dot Point comma code, fixed to 1, is used when you wish to change the display at any point to be a dot point style.  The dot point style is useful when transferring models to AutoCAD DXF files where all points may be required but hidden when no height is displayed.  This comma code can be added automatically when deleting point height text.
