===Automatic Creation=== | |||
Cross sections can be created automatically using the ''Boreholes'' | '''Auto-Create Blank Cross Sections''' menu command. This uses a triangulation process to determine the most likely connections between boreholes. The top and/or bottom arcs of the new cross sections can be warped to match the elevation of [[GMS:TIN Module|TIN]] surfaces using the ''Snap Cross Sections to TIN'' dialog which appears when the ''Boreholes'' | '''Auto-Create Blank Cross Sections''' command is executed. Snapping the tops and bottoms of cross sections to TIN surfaces can also be done at any time via the ''Boreholes'' | ''Advanced'' | '''Snap Cross Sections to TIN''' menu command. Keep in mind, however, that warping the top and bottom of a cross section may interfere with the internal polygons that are defined in the cross section, so snapping to a TIN is best done before filling in the cross sections. | Cross sections can be created automatically using the ''Boreholes'' | '''Auto-Create Blank Cross Sections''' menu command.

When a borehole cross section is first created, it is made up of a set of default lines. The figure below shows a default cross section. Notice that "arcs" (polylines) have been created defining the top and bottom of the cross section and an arc (polyline) has been created for each segment in the boreholes. | When a borehole cross section is first created, it is made up of a set of default lines.

The ''Boreholes ''| '''Auto-Fill Blank Cross Sections''' menu command can be used to automatically fill in all existing blank cross sections.

To edit a cross section manually, use the [[GMS:Borehole Tool Palette|'''Select Cross Section''']] tool and select a cross section. The ''Cross Section Editor'' dialog can be then opened by selecting the '''Cross Section Editor''' command from the ''Borehole'' menu while either a single or a series of cross sections selected. It is also possible to launch the ''Cross Section Editor'' dialog by double-clicking on a single cross section. The next figure shows a finished cross section. | To edit a cross section manually, use the [[GMS:Borehole Tool Palette|'''Select Cross Section''']] tool and select a cross section.

The ''Cross Section Editor'' in GMS 6.5 has been updated to allow for the display and editing of multiple borehole cross sections. The ''Cross Section Editor'' has a set of tools and options used to create, edit, and view the cross sections. The tools used to create the nodes, polylines, and polygons are similar to the tools available in the [[GMS:Map Module|Map module]] used to create feature objects (points, arcs, and polygons). The following tables describe the tools and display options available in the ''Cross Section Editor''. | ||
