Copy line to model

Function copies the breakline until it intersects with given terrain model. Additionl points with given interval can be added to the line for better accuracy. For each point, function checks if it is below or above model. This determines the direction and sign of the slope. Force slope setting can be used to force slope upwards or downwards.

Save button saves copied lines to the active vector file. With the Shift-key copy is activated automatically as an original line. If result contained several lines, first one is activated.

Surface, Code

Surface and code for copied breakline. Asterisk (*) uses the original line values. Browse buttons open code list and settings remember ten last used values.

Left, Right, Both sides

Line is copied to the left, right or both sides.

Point interval

If this value is not zero, original line sections are divided with given interval. Interval is rounded down to make division equal within section.

Cut slope, Fill Slope

Cut slope is used when the original line is below model and fill slope is used when the line is above model. Slope sign does not matter. Original line intersections with model are automatically added to line before copying.

Value zero skips slope calculation and removes unnecessary points from copy.

Force slope

Forces slope according given sign. Negative slope goes downwards and positive upwards.

Keep loops

In certain cases there will be loops after copying. Set this option on to not remove loops automatically.

Copy original line

Makes copy of original line. Otherwise interval calculation and possible intersections with model are made directly to the original line.

Terrain model, dZ

Used terrain model name. List displays all terrain models which are in use in the element list. If the calculated point is outside of model, new point is not created for than part. Value dZ can be used to raise or lower model height before calculation,
