Edit Layer¶

Use this dialog to create or edit layers in the active profile.

Where do I find the dialog?¶

Right-click in the horizontal list field for layers and select Properties...

Editing Methods¶

You can edit the geometry via the properties dialog or by using grips.

Edit via Properties Dialog¶

Manual Editing in the List¶

Use the context menu in the list (right-click when the mouse pointer is in the list).

The Code Column¶

The content of the code column varies depending on the layer type: theoretical or physical.

For physical layers generated from map layers (strata), the code column will show Grid or Dbase, indicating whether the points are generated from the grid (raster) or from original data. New points you insert manually in the profile will get the code Manual.

Note

Points with the code Grid or Dbase do not change status even if you move them manually.

For theoretical layers established from a Gemini road project (automatic method) or VIPS road project (manual method), the column will contain the surface number (VIPS surface numbering). When you select a surface in the list, the corresponding surface is highlighted in the cross-section. See the section on VIPS Surfaces for more details.

New points you insert manually in the profile are not automatically assigned a code value. You must manually assign a code value to each point in the list afterwards. It is recommended to use VIPS codes. If you want to insert codes between, for example, surface 1.01 and surface 1.02, you can use 1.0101, 1.0102, etc.

Warning

Points in layers that will be exported to total station/GPS or machine control must have codes. The program draws lines between points with the same code.

As shown in the figure, you cannot assign arbitrary codes to the points.

The Radius Column¶

The radius column is used in connection with tunnels. Positive drawing direction is clockwise. If you select a radius in the list, you will see that the point is at the end of the surface.

The Type Column¶

This column is used for tunnel layers. You can choose between:

None
Base
Vault

You will also find this column in the tunnel contour dialog for manual description. The point type is set when you build cross-sections from these.

Automatic:

If you build tunnel and tunnel blasting profiles with parametric description, the points get the type Vault.
If you build a trench from road tables, the points get the type Base.

Dynamic Editing in Cross-Section¶

You will find the functions for dynamic editing in the cross-section in the context menu (right-click when the mouse pointer is in the profile).

Finish and Save¶

This option ends editing and saves the layer. You can also click OK in the dialog.

Insert Point¶

This icon must be active for you to be able to insert points interactively on the screen. To insert a point before the first point, select the top point in the list. To insert a point after the last point, select the empty line below the bottom point in the list.

Warning

When you start digitizing an empty layer, you must go from left to right. If you go the opposite way, among other things, the material types that use this layer will not work. You can fix this with the Sort by distance function, see below.

Follow Layer¶

With this function, you can automatically snap to all intermediate points in a layer. Activate the function during editing and snap to the first and last point on the layer you want to follow.

Sort Clockwise/Counterclockwise Around a Point¶

For these options, you must first select the points you want to sort. Do this in the list in the dialog. Then select the function and left-click on the screen to specify the point you want to sort around.

Figure: After sorting

Close Contour¶

Use this function to close a layer. Such polygon layers are used, among other things, when calculating volume with calculation type Polygon.

Insert Point with Undefined Elevation¶

Use this function to define a gap in a layer. It can also be used to define multiple polygons in a layer.

Figure: Point with undefined elevation

Move Point¶

Use this function to move a point. Select the desired point (the point is marked with a small cross) and specify a new location on the screen.

Delete Last¶

Use this option to delete a point. Select the desired point and execute the function.

Add Line Length¶

A useful function for creating a new point relative to another. The program asks for the slope and distance to the next point to be created.

Using Helplines¶

Often, the options on the toolbar are not sufficient to construct the line as you want. In these cases, you can use helplines. Helplines are described in detail in the section Helplines and Coordinate Geometry.

Tip

Helplines can be enabled directly in edit mode by pressing the [Ctrl] key.

Using Snap Functions¶

When constructing lines, you can activate various snap modes. These are found on the lower toolbar.

Edit via Grips¶

You can edit existing lines via Grips.

On the toolbar, you will find the icon to enable or disable grips editing. By pointing to a grip handle, you will see a tooltip that tells you what happens when you left-click the point. Other relevant options appear when you right-click.
