Create Model

Use this dialog to create new models: SFI, XFI, and EFI.

Where to find the dialog

Right-click in the vertical model list field and select Create...

About templates

The program automatically selects a template based on the chosen model type. You can override the template selection by clicking the button with three dots. A template may include predefined mass types.

Procedure

  1. Right-click in the model list.
  2. Select Create...
  3. Select the model type.
  4. Optionally, select a template for the model by clicking the button with three dots. For SFI models (roads), you typically select a template according to the desired road class.
  5. Enter a file name for the new model in the Name field. If you want to save the file somewhere other than the project folder, click the button with three dots and browse to the desired location.
  6. Click Create to open the model properties dialog.

Details about EFI models

EFI models can be of two types:

  1. Volume contour (layer to layer)
  2. Excavation pit

Volume contour

Volume contour is used for mass calculation between two physical layers. The data for the layers can be measured or constructed, for example, created with the Build cut/fill from line polygon... function.

Based on the boundary contours of the layers, the program automatically calculates the areas where both layers are defined. This requires that the layers have boundary contours and that the terrain grid is set to undefined outside these.

Shaded areas illustrate mass type

Note

If you create your own templates for mass between layers, you must use the layers 98: BOTTOM PHYSICAL LAYER and 99: TOP PHYSICAL LAYER. The program will then automatically replace these with your selections for layer 1 and layer 2 in the dialog.

Excavation pit

With the Gemini DigSite module, you get access to extended functionality, including support for many theoretical layers and calculation of cut/fill angles. You can also move the excavation pit dynamically in XY and Z, and have it recalculated.

Excavation pit: A = Cut, B = Fill, C = Boundary contour, D = Mass type, E = Kt.
