Sections
Leapfrog Geo supports the following types of sections:
- A typical cross section is a vertical plane with an image or geologic cross section applied to it. In Leapfrog Geo, this type of cross section can be created directly in the scene, from the slicer or from an imported image.
- A long section is one section or a series of sections that deviates from a straight line. In Leapfrog Geo, a long section can be created from a polyline drawn in the scene or from any line object in the project.
- A serial section is a series of typical cross sections taken at an offset from a single base section.
- A plan view is a special horizontal section providing an overview.
A section layout assembles a section on a page alongside supporting elements such as a title, legend and scale bars.
A plan view layout is a special section layout for horizontal plan sections, which can be added as an element to a section layout.
Layout templates simplify the creation of section layouts by establishing a common design that can be applied to similar section layouts.

Exporting Sections
Sections can be exported in the following formats:
- DXF Files (11/12 [AC1009]) (*.dxf)
- AutoCAD Drawing Files (2013/LT2013) (*.dwg)
- Bentley Drawing Files (v8) (*.dgn)
Another way to export a section is to create a section layout and then export the section on the section layout as a PDF, SVG or PNG format file. Exporting a section layout allows you to have control over the section layout, not just the section. You can customise the page layout and include multiple evaluations and annotations. See the Section Layout Editor topic for information on using the section layout editor.
Exporting a section as a DXF file (*.dxf) exports a series of DXF lines created from the intersection of the evaluation volumes and the section plane. The lines generated from each volume are saved as separate layers in the file.
For serial sections, the section will be exported in a single file with a collection of DXF lines based on intersections between the selected evaluation and the section planes.
To export a section in one of these supported formats, right-click on the section in the project tree and select Export. In the window that appears, select the evaluations you wish to export with the section:
If you wish to change the name used for exporting one of the evaluations, double-click on its name, then enter the new name.
The 2D Analysis tab contains two options, Flatten to 2D and Simplify.
When you enable the Flatten to 2D option, the section will be flattened into the X-Y plane, making Z uniform across the section. You can change the origin, if required. The Flatten to 2D export option is available for:
- Regular cross sections
- Cross sections created from images
- Child sections of serial and alignment sections
- Child sections of long sections
The Simplify option is useful when the file is being exported for use in finite element slope stability packages. Enabling Simplify evens out the node spacing for model and line evaluations by setting a minimum allowable distance between nodes. Increasing the Minimum spacing setting reduces the number of nodes included but can result in loss of detail.
