Add a Layer to the GM-SYS 3D Model

Use the Add Layer Below context-menu option to subdivide the model volume by inserting a new layer surface beneath an existing layer. The new layer automatically inherits all of the properties from the layer above. The property distributions in the model may be refined by assigning different properties to the new layer.

Add Layer dialog options

Insert below	Select the layer beneath which the new layer will be inserted. If this action was launched by the layer context menu, this field should be correctly populated.
Elevation from	Select whether the elevation of the layer is to be specified using a grid or a constant value.
	Grid Specify the grid that contains the elevation of the new layer. If Grid selected, the Elevation grid parameter will appear below. Constant Specify a constant elevation for the layer. If Constant is selected, the Elevation parameter will appear below.
Elevation grid (or Elevation)	Select the elevation grid to use for the elevation of the layer , if Grid selected above. Specify the elevation to use for the elevation of the layer, if Constant selected above.
Layer name	Enter a name for the new layer that describes it in terms of the model or geology.

Application Notes

The new layer grid is reprojected, resampled, and clipped to match the model. If there are dummies within the resulting grid, they will be filled automatically if the percentage of dummy values does not exceed 75 percent. Layers are allowed to be coincident, but may never cross. If there are potential crossings, you will be given the option to resolve the conflicts or cancel the operation.
