The second page of the code prefix property sheet is called Line and an example of this is shown below. The fields in the page allow you to define how any lines joining the points of a feature using the current code prefix are to be displayed.
The Enabled check button allows you to specify whether a line will be displayed or not. If it is ticked, a line will be displayed using the parameters in the dialog. If not, the items in the property page will be disabled.
Layer, Style and Pen
The Attributes group allows you to define graphical attributes of the line using the Layer, Style and Pen fields. A preview window shows an example of the line. The Lines group consists of a series of check buttons which further refine the line parameters. Most of these are used in specific circumstances and will be described later. There are two that are more general in nature.
There are dimensions and comma codes that allow n4ce to display parallel and offset lines using the surveyed line feature and to construct additional points along the line feature. In normal circumstances, these lines are still displayed but there are no points at the line apexes. If Commit Constructions is checked, n4ce will create new features to represent the parallel lines or add additional points for corners and line formations. Any offset lines will be moved from their surveyed location to the offset position as displayed on the screen.
Width scalable, (such as a hedge). The line that is displayed will be scaled such that the width of the complex line pattern is controlled by the dimension. Note this functionality is kept for complex line styles.
The attribute button Auto Close automatically create a line from the last point back to the first point. This can be used where the feature represents a building footprint or a pedestrian refuge in the middle of a carriageway.
Force In DTM
The Force in DTM check button allows you to ensure that the line segments of the line feature form part of the DTM triangles. This is necessary where there are sharp changes of slope such as at the tops of embankments.
