Polylines

Leapfrog Geo imports many common polyline formats and also has tools for drawing and exporting polylines. See Import Polyline below. Polylines imported into Leapfrog Geo are stored in the Polylines folder.

There are three ways to create polylines in Leapfrog Geo:

• Create a new polyline using the Polylines folder. These polylines are stored in the Polylines folder.
• Create a new polyline as part of working with another tool. For example, a polyline can be drawn to create a lateral extent in a geological model. These polylines are stored in the tool used to create them and cannot be used elsewhere in the project unless they have been shared. To share a polyline, right-click on it and select Share. The polyline will be moved to the Polylines folder and can be used elsewhere in the project.
• Create a new polyline from a GIS line. To do this, right-click on the GIS lines object ( or ) in the GIS Data, Maps and Photos folder and select Extract Polyline. The new polyline object will appear in the Polylines folder. It is not linked to the original GIS lines object.

Polylines can be drawn using the curved polyline drawing tool or the straight line drawing tool. See Drawing in the Scene for more information on both tools.

Polylines can be exported in the formats described in Export Polyline below.

Import Polyline

Polyline formats Leapfrog Geo supports include:

• Datamine Polylines (*.asc)
• Surpac String Polylines (*.str)
• Gemcom Polylines (*.asc)
• Micromine Polylines (*.str, *.asc)
• MineSight Polylines (*.srg)
• Gocad Polylines (*.pl, *.ts)
• Drawing Interchange Polylines (*.dxf)
• Leapfrog Polylines (*.lfpl)
• Leapfrog Polylines (*.csv, *.txt)

There are two ways to import a polyline:

• Right-click on the Polylines folder and select Import Polyline. In the Import Polyline window, navigate to the location where the polyline file is saved and select it. Click Open.
• Drag and drop polyline files directly into Leapfrog Geo.

If the polyline file is in Leapfrog, Gocad or DXF formats, the importing will start immediately. For all other formats, the Polyline Import window will appear. If the polyline file is in one of the standard formats listed above, the default settings can be used. Click Import to finish the process. If, however, you wish to specify polyline import parameters, two pieces of information are required:

• The columns the polyline vertex coordinates are in
• How the polyline sections are separated in the file

Select the vertex coordinate columns by clicking on the heading at the top of a column and selecting one of East (X), North (Y) or Elev (Z) from the list.

When importing a file that has multiple features, you will be prompted to select which ones to import. You can also choose to:

• Import the features as separate objects. Each feature will appear in the project tree as a separate object.
• Flatten all features into one object. Leapfrog Geo will treat all features as a single object.

The polyline will be imported and added to the project tree under the Polylines folder.

Reload Polyline

Reloading data is necessary when the imported data is modified externally. To reload a polyline, right-click on it in the project tree and select Reload Data.

Select the file to be reloaded and click Open. The polyline will be updated, as will any dependent objects.

Export Polyline

Export a polyline by right-clicking on it and selecting Export. Leapfrog Geo exports polylines in the following formats:

• Leapfrog Polylines (*.lfpl)
• Leapfrog Polylines (*.csv)
• Drawing Interchange Polylines (*.dxf)
• Surpac String Polylines (*.str)
• Gocad Polylines (*.pl, *.ts)
• MineSight Polylines (*.srg)
• Datamine Polylines (*.asc)
• Micromine Polylines (*.str, *.asc)
