You can set the styles for line layers in two ways: through the Styles Tab and the Layer Style Panel.
Styles Tab
The Line Style group in the Styles tab is used to set the styles for line objects in line layers and the outline styles for area objects in area layers. The functions in this group are only available when the selectable layer is a line layer or an area layer.
- Symbols
The Symbols drop-down button in the Line Style group is used to set the style for line objects in line layers or the outline style for area objects in area layers.
- Click the Symbols drop-down button to pop up the line symbol resource list. The upper part of the list displays the user's recent symbols, and the lower part provides the system default root group symbol library. Users can select a symbol from the list as the symbol style for line objects in the current line layer or the outline style for the current area layer.
- Users can also click the More Symbols... button at the bottom of the line symbol resource list. In the popped-up Line Selector window, set the symbol style for line objects or area outlines.
- When a user selects a line symbol style, all line objects in the current line layer or the outlines in the area layer will be displayed in real-time with the selected line symbol style.
- Width
The combo box to the right of the Width label is used to set the line width for line objects.
- Users can set the width of the line symbol through the options in the combo box drop-down list. Alternatively, they can enter a value in the combo box and press Enter or when the text box loses focus to apply the line width setting.
- The precision of the line symbol width value is 0.1, and the unit is millimeters.
- Additionally, some symbols provided in the line symbol library resource are special symbols in professional fields. The line width is fixed, and modifying the width of such symbols is invalid.
- Color
The color button in the Line Style group is used to set the color for line symbols in line layers.
- Click the drop-down button to the right of the color button. Users can select a default color or customize other colors from the popped-up color panel. After confirming the line color, the color settings will be applied to the line symbols in the current line layer.
- After users set colors using the Color Library, the Recent Colors will be listed in the color panel.
- Additionally, some symbols in the line symbol library resource are special symbols in professional fields (mainly raster symbols). The color is fixed, and modifying the color for such lines is invalid.
Layer Style Panel
- Two ways to open the Layer Style Panel:
- Double-click the point layer in the layer manager.
- Right-click the point layer in the layer manager and select the Layer Style button.
In the Layer Style Panel, you can set the line symbol style, line width, and line color style. The organization of this panel is the same as the Line Selector. For detailed descriptions of styles, please refer to Line Symbol Style Settings.

- The current settings take effect in real-time for all line objects in the entire line layer.
