Define annotations

For the cross-section method, we can define annotations following the same principles as for mass types. These rules can also be most conveniently defined in the windows for longitudinal and cross-section editing.

Figure: The Annotation tab in the horizontal list field in profile editing windows

The annotations are stored in the SFI model in the same way as mass types. This means we can turn the annotations on/off in presentation drawings in the same way as with layers and mass types.

The annotation function is flexible and can be used for many types of tasks. It comes with a template that we can use as a starting point. Select Use template... in the dialog for SFI properties... and select Påskrifter.sfi from the Sys folder.

Right-click in the horizontal list field for annotations and you will get the option New annotation....

Overview of annotation methods

In total, we have a number of different annotation methods:

Annotation	Longitudinal profile	Cross-section
3D lines in layer		x
Difference between layers	x	x
Extra lines		x
Surfaces in layer		x
Heights in layer	x	x
Layer offset	x
Minimum difference between layers	x	x
Points in application layer	x	x
Point clouds in application layer	x	x
Tunnel contour		x
Tunnel contour angles		x
VA line definition data		x

The table above shows where the different methods can be used. Furthermore, an annotation in the window for cross-section editing will apply to all profiles where the layers are defined.

Examples of annotation methods

Below are shown examples of using various annotation methods.

Surfaces in layer

Annotation method: Surfaces in layer
Layer: Teo. 0: Surface
Show values: Width
Placement: Along horizontal line
Offset: 5

Note

We can check "Rotate text 90 degrees" if there is not enough space.

Tunnel contour

Annotation method: Tunnel contour
Layer: 31: Tunnel blasting profile

Difference between layers, example 1

Annotation method: Difference between layers
Layer: Teo. 31: Tunnel blasting profile
Difference layer: Teo. 31: Tunnel blasting profile
Difference layer 2: Fys. 90: Scanned tunnel
Targeting method: Line with annotation in extension
Approx. density: 0.50
Maximum difference: 2.00
Use points in layer: On
Use points in difference layer: On
Remove nearby points: On
Prioritize points with min. deviation: On

Difference between layers, example 2

Annotation method: Difference between layers
Layer: Teo. 0: Surface
Surface selection: (-2.01),(2.01)
Difference layer: Fys. 90: Scanned tunnel
Targeting method: Line with annotation in extension
Approx. density: 0.50
Max. difference: 2.00
Use points in layer: On

Minimum difference between layers

Annotation method: Min. difference between layers
Layer: Av.snitt 300: Buildings
Difference layer: Av.snitt 451: Stormwater
Placement: Along horizontal line
Distance from CL: 0

Heights in layer

Annotation method: Heights in layer
Layer: 1: Terrain form
Approx. density: 5
Use points in layer: On
Placement: In the profile
Offset: 1

Extra lines

Annotation method: Extra lines
Offset: 1

If you check Draw offset coordinates under Options for extra and 3D lines, the offset between the centerline and the selected extra line(s) from the corresponding dropdown menu is calculated.

Points in application layer

Annotation method: Points in application layer
Layer: 90: Tunnel
Selection depth: 0.5 (0.25 in front and behind profile number)

Note

The annotation shown is how far away from the actual profile the point is located.

Point clouds in application layer

Annotation method: Point clouds in application layer
Layer: 90: Tunnel
Selection depth: 0.5 (0.25 in front and behind profile number)

Layer offset

This method is used, for example, to show the terrain to the side of the centerline.

Annotation method: Layer offset
Layer: Fys 1: Terrain surface
Side distance: 5 (5 meters to the right of the centerline)

Note

Cross-sections must be generated along the line as the annotation retrieves heights from these.
