Export to Field¶
Use this dialog to export data from the SFI model to total stations or external formats.
Available Formats¶
Formats for Road:¶
- LandXML cross-sections
- Leica DBX database (requires LeicaSdkModuleForGemini.msi to be installed)
- LandXML 3D lines
- LandXML breaklines
- LandXML breaklines and triangle net
- Trimble DC
- Trimble RXL
- Trimble PRO
- Trimble GCS900 (requires FileFlipper to be installed)
- Trimble Earthworks (requires FileFlipper to be installed)
- VisualMachine LandXML 3D lines
- Topcon LandXML cross-sections
- Topcon RD3 database
- Bomag
- HAMM
Formats for Tunnel:¶
- Leica DBX database (requires LeicaSdkModuleForGemini.msi to be installed)
- LandXML
- Trimble TXL
- IREDES curvature 2D
- IREDES curvature 3D
Warning
When exporting tunnel Leica DBX database, the following error message may appear:
Export to Roadrunner FAILED: "ERROR: code 4 - Conversion failed"
This error occurs, for example, if the last tunnel profile is outside the horizontal curvature. The solution is to edit the profile number to be within the line, for example, change the profile number from 428.138 to 428.136 for the tunnel contour.
Formats for Tunnel Cross-Section Layers:¶
- Leica DBX database (requires LeicaSdkModuleForGemini.msi to be installed)
- LandXML
- Trimble TXL
- IREDES curvature 2D
- IREDES curvature 3D
Info
In this export, the result layers (contours) in the cross-sections are exported. During export, the profiles are rotated to zero rotation, and identical or redundant profiles are removed.
A rotation table specifies how the layers should be rotated along the centerline.
Tip
Note that composite layers can be exported using this method, and manual edits in the cross-section layers will also be included.
Exporting tunnel cross-section layers is therefore a flexible export, offering more options than direct export of table values.
Setup¶
For some formats, the Setup... button becomes active. Here, you can set options that, among other things, affect the naming convention for the lines. Refer to the dialog help for further details.
Export Layers¶
By checking this option, you can export layers in the SFI model. The various theoretical layers in the cross-section then become selectable in the list.
Note
For some formats, it is only possible to export one layer at a time.
Warning
For 3D line formats, it is not possible to export layers that are offset from the centerline, meaning layers that do not contain the center point. In these cases, you can solve this by creating a composite layer and exporting it.
If the option is not checked, only the centerline (3D line or horizontal curvature with or without vertical curvature) will be included.
Surface Selection¶
You can limit the SFI model laterally by specifying which surfaces to include. This is done by entering a text string with the surface codes.
| String | Description | Note |
|---|---|---|
| -(1.01),(1.01) | Only surfaces -1.01 and 1.01 | For formats that provide 3D lines, the lines at the surfaces' endpoints are exported. |
| (-2.09:2.09) | Surfaces from -2.09 to 2.09 inclusive |
Profile Interval¶
You can extract a part of the SFI model by setting the profile area. Enter From profile and To profile.
Note
The program only cuts the cross-sections at these profile numbers. The centerline is cut at the element before and after.
Example
Elements marked in green are included even if From profile and To profile specify a smaller part of the centerline.

Maximum Circle Deviation¶
These options only apply when exporting layers in the SFI model. Otherwise, they are grayed out.
Circle Deviation XY¶
Max. circle deviation XY is only active for formats that provide 3D lines. For other formats that provide cross-sections, the option is grayed out.
All 3D lines in the SFI model are divided into line segments (including the centerline's horizontal curvature). You can control how well these segments fit the arcs in the plan view (XY). The value in the Max. circle deviation XY criterion determines this. If you set the circle deviation to 0, you only get segments from profile to profile.
Example
Max. circle deviation = 0
Figure caption: A = Cross-sections, B = Centerline
Circle Deviation Z¶
The centerline's vertical curvature will also be divided into line segments like the other 3D lines in the SFI model. You can control how well the segments fit the arcs in the vertical curvature in the same way as in XY (plan view).
Tolerance¶
This option is active for tunnels.
Identical and redundant contours and tunnel rotations will be deleted during export.
You can specify the tolerance you want to use. The tolerance is given in meters and applies to profiles and contours (distance, height, and radius).
Info
For rotations, a fixed tolerance of 0.0001 is used.
The function maintains the link between profiles and contours by updating the references for the data that are deleted.
