The"Earth grading" serves to define terrain earth grading. The earth grading cannot be defined in the first stage of construction.
The earth grading should considerably simplify an input of excavation pits or embankments. The essential part of earth grading is the shape of bottom, from which the slopes of excavations or embankments are directed towards the original terrain. The original terrain points and edges, found in the region of earth grading, are automatically removed during generation.
More than one earth grading can be defined within a single stage of constructions. They must not, however, cross each other. If that happens, they need to be combined into a single earth grading. No part of earth grading can also exceed the world dimensions - in such a case one should realize that faces of earth grading may exceed the world dimensions even if the bottom is defined well inside.
The earth grading can be edited only in the stage, where it is defined. In the next, the earth grading is transferred in terms of terrain new points and edges.
With the help of table: earth grading is defined in the. The "Add" button opens the "New earth grading" dialog window, which allows for specifying the name of earth grading (by checking individual boxes it is possible to define a uniform depth of the bottom and a uniform gradient of the slope). This dialog window contains a table to introduce points, which define the ground plan (general polygon) of earth grading. To enter these points, proceed in the similar way as when defining . Pressing the "Add" button closes the dialog window and the new earth grading is inserted into the table.
The earth grading can be further modified (in the dialog window) using the "Edit" button or removed with the help of "Remove" button (more than one earth grading can be marked in the table to remove them all at once - before removing, the selected earth grading is displayed on the desktop in red). Each change is immediately reflected on the desktop.
