Polylines

Polylines are the most common interpretations used. Much of the functionality of Polyline interpretation is common to both Faults and Geopolygons.

To interpret a polyline use the draw polyline option from the Interpretations ribbon menu.

Group Display Options

Property Name	Description
Name	The name of the polyline group shown in the interpretation tree. Note the name is only available to edit in sub groups, not in the top level of the tree.
Show Nodes	Show the nodes/vertices which cpomprise the polyline. These are the original data points from when the polyline was digitised.
Node Size	The size of the vertices in the 3D window.
Line Width	The width of the trace that joins the 3D vertices.
LOD Scale	Level of detail distance
Show 3D trace	Show the trace of the joined vertices as a cylinder rather than a line.
Trace Size	The width of the cylinder comprising the 3D trace
Wireframe	Display the plane as a wireframe rather than a solid surface.
Show Planes	Show the polyline as a plane extruded along the orientation of the polyline
Show Labels	Show the polyline name as a label in the 3D view. This will show all the individual polyline names (not the group name)
Variable Extrusion	This changes the way the polyline plane is extuded, usin the geometry of the polyline as a control on the extrusion. Gives the polyline plane a smoother profile arounf corners, but can have difficulties with complex geomtries. A purely visual feature and does not affect the data itself.
Plane opacity	Change the opacity of the plane (0 = transparent, 1 = fully opaque).
Auto best fit	Enable automatic updating of the oritentation value when editing the polyline vertices.
Projection Distance	How far the plane is exturded from the polyline.
Minimum Digitiser Spacing	When interpreting polylines VRGS will not allow points to be closer than this value when using the "draw" interpretation style
Display Colour	Changes the colour used to display the polyline. The options are "pick" = the colour of the "pick" or stratigraphy defined in the collections tree. "User" which is the colour defined in the individual poylines options, and group which is the colour defined at a group level.
Default Name	The default name for new polyline interpretations. Can include variables.
Name Counter	The current number used for new interpretations. Autoincrements by 1 for each new interpretation

Name Variables

The default name for polylines can accept variables to make naming easier. Variables are formatted \{$VAR\} where var is the name of the variable.

Supported variables:

Variable Name	Meaning
\{$PICK\}	The name of the active horizon or pick
\{$USER\}	User name of interpreter
\{$DATE\}	Date

Property Name	Description
Pick Name	The name of the individual polyline shown in the Interpretation Tree.
Orientation Dip	The dip value derived from a best fit plane to the polyline vertices.
OrientationAzimuth	The azimuth value derived from a best fit plane to the polyline vertices.
Error	A measure of how good the best fit surface is to the vertices.
Colour	The colout of the polyline (used for user colour display style)
Line Style	Chage the style of the line. May be solid -, dashes --, dotted ..., or dot-dash .-.-.
Line Repeat	The repeat distance of the line style. A shorter distance will give smaller dots and dashes.
Stratigraphy	The stratigraphy or the Pick. Nominally defined the age of the marker, but can be used for other classifications. Possible values are defined under Picks in the collections tree.
Comment	A text comment applied and stored with the polyline.
Extrude along strike	Extrude the plane along strike rather than along dip. This is the default.
Polyline Length	A purely informative value that defines the length of the polyline.
