Editing the [Polyline]¶
Description: Define geographic data defined as Polyline. Figure 208 shows an example of the [Polyline].
Geographic data group in which [Polyline] can be defined
[Polyline] can be added only to Geographic Data group [Reference Information].
[Polyline] on [River Cross-section Window]
On [River Cross-section Window], the intersection points between [Cross-section] and [Polyline] are displayed.
Using this function, you can add [Polyline] as reference information on [Pre-Processing Window] first, and you can edit the cross-section shape, considering the [Polylines] that corresponds to roads, for example.
Figure 209 shows an example of [Polyline] shown on [River Cross-section Windo].
Please refer to Operation in the River Cross-section Window for the detail of [River Cross-section Window].
Drawing charts with calculation result interpolated on polylines
iRIC 1.0.14 and later can draw charts with calculation result interpolated on polylines. Please refer to [Graph Window] for detail.
[Add New Polyline]¶
The procedure to add a new Polyline is as follows:
- Select the [Reference Information] under [Geographic Data] in [Object Browser] (Figure 210).
- The operation below adds a new Polyline to [Object Browser], and that Polyline is selected.
Menu bar: [Geographic Data] (E) –> [Polyline] (L) –> [Add New Polyline]
- On the canvas, add vertexes to the Polyline by left clicking (Figure 211).
- Double click or press the Enter key to complete defining the Polyline.
[Add Vertex] (A)¶
Description: Adds a vertex to the [Polyline].
When you select [Add Vertex] and move the cursor to the edge of [Polyline], the cursor changes to that shown in Figure 212. 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 [Polyline].
When you select [Remove Vertex] and move the cursor onto the vertex you want to remove, the cursor changes to that shown in Figure 213. Left clicking will remove the vertex.
[Edit Coordinates] (C)¶
Description: Edits the coordinates of the vertices of the [Polyline].
When you select [Edit Coordinates], the [Polyline Coordinates] dialog (Figure 214) will open. Edit the coordinates and click on [OK].
