Settings

1- Points and breaklines - Select this to export the surface, as well as the points, breaklines, contours, and boundaries used to create the surface.

2- Triangles - Select this when you only want to export the triangles defining the surface. This option also handles holes and islands in the data.

Both 1 and 2 - Select this when you want to export a surface with (1) points and breaklines and a surface with (2) triangles.

Note: Use this setting to export surface data in a way that earthwork systems/machines can use. Exporting surfaces that include points, breaklines, and triangles is the most versatile option and therefore best suited for a wide variety of recipient applications, including Trimble Earthworks.

Optimize for data - Select this to let the program choose the best export method.

If the surface you have selected for export contains any internal data (surface was imported in a TTM or LandXML file), it will export as triangles.

If the surface only references external data (surface was created entirely in this program), it will export as points and breaklines.

Note that If you are exporting a portion of a surface that is clipped by a boundary, all data in the clipped portion is made internal.

Note: This setting has no effect if the file does not contain surfaces.

Always ask - Select to automatically check for points with the same Point ID. If any are found, you are prompted to import all duplicates, ignore all duplicates, or cancel the import.

Export all - Select to have all points export, including those with duplicate point IDs.

Ignore all - Select to have only points without duplicate point IDs export.

Note: This setting has no effect if the file does not contain points.
