Options¶
Use this dialog to change construction settings for the main surface and side surfaces (cut/fill), as well as other settings for labeling and displaying information in the excavation.
Where to Find the Dialog¶
In the toolbox in the terrain model drawing, select Excavation and then the Options tab.
Parameters for Cut/Fill¶
The main surface is constructed based on points and lines within the boundary contour. The side surfaces are constructed based on cut/fill parameters defined for the boundary contour.
The points where the cut and fill surfaces meet the terrain (the outer line) are found by the program using the cross-section method. The boundary contour is the centerline, and profiles are generated according to the fields Profile Interval and Distance Right Side.

A* = Profile interval, B* = Option for rounding
There are also other settings that affect the construction of cut/fill surfaces.
Sometimes, automatic rounding in outer corners does not work optimally. In such cases, you can turn off this option so that you only get one profile exactly at the corner. If you want rounding on some outer corners, you can manually add small roundings in the boundary contour.
In other cases, automatic clipping in inner corners may not work as desired. You can then turn off this automation and manually add boundary lines for cut/fill.
Parameters for Triangulation¶
You can set some options for triangulation of the excavation.
The option Close gaps between side surfaces and main surface is off by default.

The option Close gaps between side surfaces and main surface is off
When this option is off, the triangle nets for side surfaces and main surface are independent. Not all triangle points are shared at the transition between side surfaces and main surface, and gaps may occur here, especially if roundings are used.
If you check this option, the transition between the triangle nets will match exactly.

The option Close gaps between side surfaces and main surface is on
This results in more triangles in the main surface and may reduce performance for large excavations. This option is typically used if you want a continuous triangle net for the entire excavation, for example, for export to the field.
With the option Max. length of a breakline element, intermediate points are generated on the lines that form the basis for the main surface. This option is rarely used in excavation.
You can also set a Minimum point distance. If the distance between points is less than this, the routine treats the points as identical.
Shared Parameters for Cut/Fill and Triangulation¶
With this option, you specify the maximum circular deviation, i.e., the distance between the chord and the arc, in plan and elevation. Based on this parameter, all arcs are divided into several line segments. The value indicates how closely the line segments follow the arcs.
Allow Dynamic Move/Rotate of Excavation¶
With this option, you can allow dynamic moving or rotating of the excavation. When this option is enabled, you can use standard functions to move the object via the context menu.
Excavation Class¶
You can assign an excavation class (from 1 to 9) to the excavation. This allows you to link different textures or colors to the excavations during rendering.
Grid Density for Mass Drawing¶
Here you set the grid density that the program will use when drawing the mass result in plan and 3D. This option takes effect if you have checked Draw masses in the Excavation tab.
Note
The maximum density that takes effect is determined by what is set under Settings Gemini Terrain....
Interval for Elevation Labeling¶
The label line is one of many lines with different functions. You use this line to add elevation labels. Interval for elevation labeling determines how closely you want to write elevations along the line. Only the labels are displayed on the screen, meaning the line is invisible except during editing.
Note
0 in the field means you only get elevations at the break points.
