The fifth page of the code prefix property sheet is called Shape and an example of this is shown below. A shape feature is a very simple graphical object, such as a circle or a rectangle, and is constructed using the co-ordinates of a small number of points. They are most commonly used for street furniture such as post, poles and manholes. The fields in the page allow you to define how any shapes that are required for a feature using the current code prefix are to be displayed.
The Enabled check button allows you to specify whether a shape will be displayed or not. If it is ticked, a shape will be displayed using the parameters in the dialog. If not, the fields on the property page will be disabled.
Layer, Pen, Line and Fill Style
The Layer, Line Style and Pen fields define the graphic attributes that are to be used. The Fill Style field defines a fill style that could be used to fill the shape of the screen. When the fill is exported to an AutoCAD DXF file, it is exported as a solid hatch using the foreground colour of the fill style.
The Type field defines the type of shape to be created and these are described in the following sections. There are various check buttons and these will be discussed with the shape types to which they are relevant.
This can be used on two or three point rectangles which you need to remove one side from automatically. The example below depicts two and three point rectangles with the option enabled. The open rectangle can be used for detail such as a house extension or a loading bay.
Alternate Points should be enabled when you use a two point symbol such as a tree canopy, and a one point shape such as a one point circle for its truck. Without Alternate points enabled the second point that defines the scale of the symbol will also have a circle attached to it.
Adjust Survey Distance
For any Circular shape this option allows Total Station observations (Not GNSS) to be offset along the line of site by the radius of the shape. Therefore as long as the observation is taken to the center of the tree, and the Radius, Diameter or Circumference supplied, the center point of the shape will be moved automatically into the correct place.
This option allows attributes which control the size or dimensions of a shape to be carried forward until they are changed. If the dimension is not attached to one of the points of the shape and there is no default provided in the fields of the code prefix, a value of 1.0 is assumed.
Hide Second Points
The Hide Second Points check button is available for all multi-point shapes. If this is ticked, only the first point used for each shape will be displayed regardless of the point display settings. Also, any text or annotation on the second or subsequent points will not be displayed.
