Layer Management

Description：Vector editing is managed with layers, which means a file is treated as a layer. Clicking the triangle button of the "File" will show the drop-down menu, including the "New File", "Open File", "Save File", "Remove File" and "Export File" functions.

Add Layer

Click Layer>Right-Click Menu>Add Layer, and the "Create New Layer" dialog box will pop up.

  1. Select the layer name from the drop-down menu, including: control points, buildings, railways, roads, other roads, bridges, water bodies, administrative boundaries, cultivated land, gardens, forests, grasslands and other vegetation. Alternatively, you can directly enter the layer name as shown in the following figure:

  2. Select layer type (oint or line). If creating point layer, you need to set color and point size; if creating line layer, you need to set line color, size and type.

  3. Click the layer color to select the layer color.

  4. Size setting is between 1-10 pixel.

    Note:One vector layer can only store vector entities of current layer. If the created layer is a line layer, only lines, polylines, Bezier curves and other types of lines can be drawn in this layer. If the tool currently being used does not match the type of the active layer, the layer will turn to that the tool corresponded. The default layers for point tools are "point", polyline tools are "polyline", polygon tools correspond to "polygon" and text tools correspond to "text". When activating a tool, if the current layer type does not match and there is no corresponding default layer available, a new default layer will be automatically created.

Save All Layers

Click the "Remove All/Current Layer" function to pop up a dialog box:

Select the file type and path to save, click OK, and save the layer to the corresponding path. >Note: If the saved file extension is shp, a directory named after the layer name with _points.shp or _lines.shp will be created in the directory. #### Remove All/Current Layers #### Right click *Layer>Remove All Layers*:

  • Click "Yes" to save all/current layers and remove all/current layers;
  • Click "No" to not save all/current layers and remove layers;
  • Click "Cancel" to exit the current remove all/current layer operation.

Feature Overview

The display vertices toggle allows users to choose whether to display the endpoints of polylines, making it easier to edit entities.

Reference Plane

Feature Overview

The reference plane is a drawing plane set in the main window of the vector editing module. When drawing lines, rectangles, and polygons, the reference plane settings interface will automatically activate. During these drawing operations in the main window and associated windows, the drawn vector objects will be restricted to this reference plane.

Reference Plane

Parameter Settings

  • Show Plane: Toggle to display the drawing reference plane.
  • Transparency: Sets the transparency of the reference plane, with a range of 0-99.
  • Color: Sets the color of the reference plane. Click the button to open the color selection dialog box.
