Editing the [Polygon]¶
Description: Sets the values of geographic data within the area of the Polygon. Figure 193 shows an example of the [Polygon].
[Add New Polygon]¶
The procedure to add a new Polygon is as follows:
- Select the type of [Geographic Data] in [Object Browser] to which you want to add a Polygon (Figure 194). Note that the list of types of [Geographic Data] varies according to the solver used.
- The operation below adds a new Polygon to [Object Browser], and that Polygon is selected.
Menu bar: [Geographic Data] (E) –> [Polygon] (P) –> [Add New Polygon]
- On the canvas, add vertexes to the Polygon by left clicking (Figure 195).
- Double click or press the Enter key to complete defining the Polygon. As soon as you have double clicked or pressed the Enter key, the [Edit Elevation value] dialog will open(Figure 196). Set the geographic data of the Polygon and click on [OK]. The dialog varies depending on the type of [Geographic Data] to which a Polygon is added.
[Edit Value] (V)¶
Description: Edits data value within the Polygon.
When you select [Edit Value], the [Edit Elevation value] dialog (Figure 197) will open. Set a new value and click on [OK].
Description: Copy the Polygon to another [Geographic Data] group.
When you select [Copy], the [Select Geographic Data] dialog (Figure 198) will open. Select the [Geographic Data] group to copy this polygon, and click on [OK].
Then, the dialog to specify the value for the polygon is shown, like in Figure 199. Specify the value and click on [OK], to finish copying the polygon.
[Add Vertex] (A)¶
Description: Adds a vertex to the [Polygon].
When you select [Add Vertex] and move the cursor to the edge of [Polygon], the cursor changes to that shown in Figure 200. Left click on the line and drag it to add a new vertex. The vertex is placed where you release the left button.
[Remove Vertex] (R)¶
Description: Deletes a vertex from the [Polygon].
When you select [Remove Vertex] and move the cursor onto the vertex you want to remove, the cursor changes to that shown in Figure 201. Left clicking will remove the vertex.
[Edit Coordinates] (C)¶
Description: Edits the coordinates of the vertices of the [Polygon].
When you select [Edit Coordinates], the [Polygon Coordinates] dialog (Figure 202) will open. Edit the coordinates and click on [OK].
[Add Hole Region] (H)¶
Description: Adds the Hole Region to the [Polygon].
[Delete Hole Region] (D)¶
Description: Deletes the Hole Region from the [Polygon].
