Layer structure

You can use this function to create new layers for the selected triangulation, which are required, for example, when building paths and terraces.

A distinction is made between two situations:

On the site Here the individual layers are based on the chosen triangulation up added. With this function, for example, landfills or multi-layer structures can be created. If the triangulations of the layers are to be calculated, the upper Triangulations of the individual layers calculated.
In the area The individual layers are made up of the chosen triangulation down added. This function is used, for example, in road construction. If the triangulations of the layers are to be calculated, the lower Triangulations of the individual layers calculated.

1. Select the desired triangulation in the DTM tree and call it with the right mouse button Triangulation> layer structure on and choose whether the layer structure on the site or in the area should be created.
2. Now either select a closed boundary, if the layer structure is only to be applied to an area within the triangulation, or confirm the selection with Enter or the right mouse button to apply the layer structure to the complete triangulation.
3. In dialogue Layer structure you can either select an existing layer structure or create a new layer structure.
4. To create a new layer, click in the dark gray area in the table below. Enter the Namur, the Thickness and Offset at, define whether the edge of the layer perpendicular or should run with a slope and select whether a triangulation or a difference body should be calculated for the layers. To change the columns, press the key Tab.
5. On the tab boundaries you can define areas that should be left out if necessary.
6. With Enter confirm the information. The dialog is closed and the Quick DGM new entries are created for the layer structure (triangulations in the specified number and the corresponding difference bodies).

In the upper area of ​​the dialog you can select an existing layer structure from the list or enter a new name for your layer structure in the field. With the button [Save Template] you can save your changes. The button [Manage] opens a dialog for managing existing layer structures, in which you can enter the existing layer structures delete or make copies.

The next area shows the individual layers with their settings:

Name	Enter the material or the name of the layer here, for example.
Thickness	Define the layer thickness in meters.
Offset	Enter the offset in meters here. A positive value creates an outward offset. A negative value creates an inward offset.
Perpendicular	If the option is activated, the edge of the layer is displayed vertically. Otherwise, a slope is calculated based on the values ​​for thickness and offset.
	If the option is activated, a triangulation is calculated for the slice.
	If the option is activated, a difference body is calculated for the layer.
Surface	The calculated surface of the layer is displayed here, provided the option has been activated.
Volume	The calculated volume of the slice is displayed here, provided the option has been activated.

With a click with the right mouse button on the beginning of the respective shifts, the order can be adjusted or shifts that are not required can be deleted.

Is the option Terrain outside the selected boundary delete activated, then only the terrain within the boundary is calculated as layers. If the option is deactivated, the terrain outside the boundary is also used for the calculation.

In the lower left area, a Preview the layer structure shown. The preview can also be inserted into the drawing as a scheme. Right-click on the layer structure in the Quick DTM and choose Scheduling. You can then insert the scheme into the drawing with the mouse.

The sums of the surfaces and the volumes are displayed below the preview.

In the field Description you can store further information about the layer structure.

In order to cut out areas from the layer structure (e.g. building edges), you can use the boundaries closed objects can be defined as boundaries.

With the button [Add] you can capture existing, closed drawing objects as boundaries or boundaries with the right mouse button using the options contour (for existing, not closed objects) or To draw (for new, closed polygons).
With the button [Delete] limits that are no longer required can be removed from the list.
