The Edit area in the expert mode also differs from each geometry type to an other. In the expert mode, every geometry can be edited down to the smallest geometry - the point. This refinement allows you a lot of combinations in creating symbology.


Additionally, in the easy mode you can specify the stroke and the fill of a geometry type. The stroke and the fill are separated in each point. Every point is separated in a fill and in a stroke. Every fill and every stroke is divided into points again. Then, every point is separated in a fill and a stroke once again.

You see that you can edit every point ad infinitum. You always can stop on any process step. It can be step number one or step number 100, depending on you and your specified style that can be controlled in the preview.

  • At the beginning of the process chain, you are able to choose the specific geometry properties and the function's fill and stroke.

  • For selecting the function stroke, you will get the function graphic fill besides the properties for a normal line.

  • After that, you are able to choose an external graphic or a geometry for editing the points in the next panel.

  • Then you can edit the stroke or the area of the mark or the symbol.

To make it clear, look at the example from the style hierachy:

There are three types of strokes and detailed information can be found in the following table.

Two neighbouring symbols aren't overlapping anymore. To get a visual impression of the difference between Graphic- and Cartographicstroke have a look at the following video.

The style properties you will get in the specific functions are similiar to those in easy mode. They are regulated by the underlying geometry type that the properties can be referenced by. See Edit Area (Easy Mode).

The expert mode provides the functionality to add multiple style layers to one scale dependency. Therefore the configuration panel of the scale area differs from the easy mode. You have access to the expert mode by selecting the expert mode button. The default view is predefined. Edit the scale values on the right side. Note that the value 0 serves as an unlimited scale value. To add a new scale, right click on the default scale that you defined earlier. You will get a list where you can select the scale entry. In the same way, additional style layers can be initialized.

The following example shows how to add several scale depedencies and more style layers in one scale:

1. Edit the scale values on the right side. The example shows a style in the scale from 1 to 100000 and another style from 100001 to unlimited.

2. Add one or more layers to the scale. In the example, you see two layers that are used to specify a more detailed view in a low scale range. In the higher scale area, one layer is utilized to generalize the features` views.

Point & Text

Additionally, the expert mode provides some extra features for each underlying geometry type.

  • Unit:
  • Geometry Function:
  • Linestart: Sets the style for the first point of a set.
  • Midpoint: Sets the style for all points of a set except startPoint and endPoint.
  • Lineend: Sets the style for the end point of a set.
  • Vertex: Sets the style for all points where several edges are attached.

GMSC 2014 Geometry funtions are also available for geometry type Text.

Besides the general characteristic of the expert mode described in the general section, the line´s edit attributes do not differ from the ones in the easy mode. See here.

In addition to the expert mode property graphic fill, you can define stump edges. That means the higher the value specified in the perpendicular offset, the edges are more flattened and the symbol is bigger.

In the Expert mode, the line style used for the raster's frame can be modified. See the line edit pane for additional information. (see here)

Besides the general characteristic of the expert mode described in the general section, the dimensioning´s edit attributes do not differ from the ones in the easy mode. See here.

Geometry Collection (Expert Mode)

The geometry collection is only available in the expert mode. The view of the edit pane depends on the geometry type that you are working on. For an additonal description of how the style attributes of each geometry type can be used, see the explanations above. Ín the special type geometry collection, you are able to summarize all basic geometries.

The geometry callout looks like the following. You can set their shift, adding values to columns x/y. The technique behind the moving works is:

The value of the x column you define is summed to the x value of the coordinate. The same is done with the y value. A new coordinate results, and it is placed in the view pane, and the lines are connecting the orignal and the new point.


x-value = 200 and y-value= 10
