This tab manages the surface's breaklines. The number of breaklines is written in the "Lines:" box and you can browse between rows with the help of the arrows. The table shows the line's currently selected vertices (the figure between the arrows).
The pop-up menu is the same as in the outline tab.
Button | Description |
|---|---|
 | Used to apply a filter to the available lines. It is possible to filter by selecting lines in the main window, by keeping only closed or intersecting lines, by imposing a requirement to match a given point and radius, by minimum and maximum leaves, or by giving an elevation requirement. Filters cannot be combined. (Apply the filter by clicking on the gray button in the menu.) |
Verify the intersections of the breaklines. | |
| Add a new blank row. |
Delete the current row. | |
Delete all breaklines. | |
Detect crossing lines | |
Pick a line on the screen to add it to the list. | |
Draw all breaklines in the main window. | |
Erase all breaklines from the main window. | |
| Modify the elevation, particularly useful to set the elevation to an unknown value. The elevation will then be interpolated during triangulation. |
