The dialog box 'Drawing Rule Setup' is activated from the “Drawing Setup” dialog by double clicking a “Selection Set”, or by using the right click mouse menu when selecting objects in the viewer. This defines one or several drawing rules for the chosen/stated feature code. The range under the banner <ALL> indicates which drawing rules are available.

The left section of the dialog will show the drawing rules attached. Each drawing rule is processed in the order they appear.

The right section of the dialog show two tabs, the one marked “Used” will show attached drawing rules, while the one marked “All” show available drawing rules.

To add a drawing rule from the “All” section, double click an icon (or use the right click menu) and it will be copied to the “Used” tab section. To remove a drawing rule from the “Used” section, double click an icon (or use the right click menu) and it will be removed.

The “Drawing Rule” drivers are described in the topic Driver Setup.

A drawing rule is chosen by double clicking the desired rule. The chosen rule is copied to the banner <USED> at the same time as a banner displaying the settings for this drawing rule is created. A feature code can get assigned several drawing rules depending on the desired representation. Every drawing rule gets a banner describing the different settings.

When the drawing rule has been moved to the banner <USED> the name can be changed.

A drawing rule is deleted by double clicking on the drawing rule under the banner <USED>. A confirmation question is asked before the drawing rule is permanently removed from the set-up.

All details regarding the drawing rules are not explained here when most are self-explanatory.

This drawing rule should primarily be used on closed polygons (e.g. houses). Surfaces can be filled with a chosen color and be given an outline with a defined width.

Contour map is a unique drawing rule, which draws color variations according to the height intervals. The following options/settings are available:

• Display log: Gives an overview and statistics on the height calculations that have been carried out.
• Calculate/estimate minimum/maximum heights in a chosen section: Declares if the calculation is to be carried out based on the whole drawing or only on a certain segment/section.
• Displays objects with undefined height: The calculation is not performed on objects with undefined heights, but it gives an option of displaying them in a white color.

Drawing rule with the characteristics of a line. By combining several drawing rules for the same feature code complex lines can be produced.

Ex. 1 - defines a line with color and width and a different line with a different color and less width.

Ex. 2 - defines a line with parallel displacement on the right and an equivalent parallel displacement on the left.

Drawing rules that have the characteristics of drawing symbols along the line.

Drawing rules with characteristics of drawing height information on lines. If this is used for example on contour lines, the heights are drawn out on the contour lines.

The drawing rule that have a combined quality/characteristics. If a feature code contains both lines and points, lines are drawn for characteristics of the line and points with characteristics of the symbols.

Draws a closely defined symbol in all the points for the chosen feature code. On objects of the type line the symbols are drawn in all the lines points.

Draws text for defined feature codes if this contains objects of this type text.

Draws triangle models if these are calculated and stored in the terrain model.

To draw a “Selection Set” on the screen, one must apply “Drawing Rules” that match the objects involved. A “Drawing Rule” is applied by selecting one or several “Drawing Rules” for the task in question. The viewer will handle a request as follows:

• If an object in a “Selection Set” matches the criteria's in a selected “Drawing Rule”, it is drawn to the screen with the chosen settings.
• If an object in a “Selection Set” does not match the criteria's in a selected “Drawing Rule”, it is moved to a special selection set called “Default Drawing Rule”.
• If an object in a “Selection Set” does match the criteria's in a selected “Drawing Rule”, and is not able to draw the object to the screen, it is copied to a special selection set called “Error Drawing Rule”. This is normally an indication that something is wrong with the way the object is stored in the Quadri Database - e.g. a line object with only one coordinate.

The “Default” drawing rule is designed with the intention of providing a quick way to show the most common objects found in a Quadri database.

• Object type 2,3,7,9 =

> will be drawn as “Line” objects.

• Object type 1,6,10,99 ⇒ will be drawn as “Circle” objects, user set radius.
• Object type 8 ⇒ will be drawn as “Text” objects.
• Object type 23 ⇒ will be drawn as “Circle” objects, radius attribute value.

• Color: All defined colors.
• Text scale: This is a scale value, using a base height of 1 meter.
• Symbol scale: This is a scale value. The symbol is represented with a circle, using a base diameter of 1 meter.

The “Point” drawing rule can be used to draw single points or vertex points on a line object.

Points can be represented in two ways:

• Color: All defined colors.
• Linetype: Any AutoCAD-defined linetype. Linetypes with shape definitions will not be displayed correctly on the screen, but will be drawn correctly when transferred to AutoCAD.
• Radius: Input value in meter.

Symbol name: Formats “DWG”, “DXF” and “NPS” (Novapoint Symbol) are supported. AutoCAD's DWG will not display correctly in the viewer (shown with a dwg-tag), but will be drawn correctly when moved to AutoCAD. NPS is a simplified text-file format that can be generated directly from AutoCAD.

• Scale: A scale value lesser than 1 will scale down the symbol and a scale value larger than 1 will scale up the symbol.
• Rotation: Input value in degrees with positive values giving a clockwise rotation.
• Color: Using the color option will override the symbols own color definition.
• Rotate along line: On directional changes in a line, the symbol rotation will use the angle to the previous point as a baseline for rotation. This option is only valid with “Line Points”.

The first option “Point objects only” signifies that symbols will be inserted on single points only (object type 1,6,10,99), while the rest of the options will insert symbols as described on “Line” objects (object type 2,3,7,9). The latter option “Line - with a specific distance” requires input regarding “Distance” between the symbols along the line, and “Start offset” implies the distance from the beginning of the line to the first symbol insertion.

Input value in meters, indicating the displacement relative to the symbols insertion point.

The “Text” drawing rule can be used to draw text on single points or vertex points on a line object.

• Text Object: Displays the text attribute (dynamic record no. 4)
• Height in point: Displays the height value
• Point number (index): Displays the index number on object points
• Object Feature Code: Displays the objects feature code
• Object Group: Displays the objects group no.
• Object Name: Displays the objects name
• Object Post: Displays the objects record no.
• X, Y - Coordinate: Displays coordinates (2D) on object points
• X, Y, Z - Coordinate: Displays coordinates (3D) on object points
• Definition: Text style options
• Rotation: Input value in degrees with positive values giving a clockwise rotation.
• Rotate along line: On directional changes in a line, the text rotation will use the angle to the previous point as a baseline for rotation. This option is only valid with “Line Points”; see “Settings - Placement”.

The first option “Single Point” signifies that text will be inserted on single points only (object type 1,6,10,99), while the rest of the options will insert text as described on “Line” objects (object type 2,3,7,9). The latter option “Line - with a specific distance” requires input regarding “Distance” between the text along the line, and “Start offset” implies the distance from the beginning of the line to the first text insertion.

The “Line” drawing rule can be used to draw lines (object type 2,3,7,9)

• Color: All defined colors
• Linetype: Any AutoCAD-defined linetype. Linetypes with shape definitions will not be displayed correctly on the screen, but will be drawn correctly when transferred to AutoCAD.
• Width: Input value in meters
• Offset: A positive value will offset the object right relative to the objects direction, while a negative value will offset the object left relative to the objects direction.

The first option “None” will omit masking, while the rest of the options will mask (wipe out) a portion of the line as described. The “Width” value will be equally measured out on each side of the masking point. The latter option “Along Line” requires input regarding “Distance” between the masking points along the line, and “Start offset” implies the distance from the beginning of the line to the first masking point. Masking is often used in conjunction with inserting symbols along a line.

The “Surface” drawing rule can be used to fill and outline surfaces. A surface can be a closed polyline (object type 2,3,7,9) or surface (object type 10,99).

“Level 0” in this context signifies the main surface, while “Level 1” signifies a hole (or many holes) in the main surface. The latter option “Level 2” is a hole in a hole.

Two types of fill are supported:

• Color: The color of the fill surface
• Tolerance: Input value in meters indicating the accuracy of closure

• Spacing: The distance in meters between hatch lines
• Angle: The hatch angle in degrees, with due north being 0 degrees and a positive value giving a clockwise rotation.
• Color: The color of the hatch lines
• Tolerance: Input value in meters indicating the accuracy of closure

• Draw: Option to draw an outline around the surface
• Width: The width of the line
• Color: The color of the line
• Linetype: Any AutoCAD-defined linetype. Linetypes with shape definitions will not be displayed correctly on the screen, but will be drawn correctly when transferred to AutoCAD.

The “Height Map” drawing rule is a customizable tool for showing height variations by color. In addition there are useful options to visualize objects with incongruous heights.

• Alternatives: There are 10 predefined color scales
• Color of objects with undefined heights: The color setting for objects with a height value < -998.0m.
• Color of objects with heights turned off: The color setting for objects with “Elevation” setting “Ignore” located in the group/feature dialog
• Color of objects with negative heights: The color setting for objects with a height value between 0 and -998 meters.

• Calculate min/max heights from current view: Using this option will force the height calculations to use the objects visible in the current window, opposed to using all objects in the terrain model.
• Show report when drawing is finished: Using this option will generate a report showing in what steps the height calculation are done.

The “Horizontal Curve” drawing rule is a specially designed tool for visualizing alignments stored within the terrain model (object type 9). Alignments are highlighted with stationing.

• Linetype: Any AutoCAD-defined linetype. Linetypes with shape definitions will not be displayed correctly on the screen, but will be drawn correctly when transferred to AutoCAD.
• Color: The color of the alignment line * Width: The width of the alignment line

The “Boundary Line” drawing rule is a specially designed tool for visualizing boundary lines stored within the terrain model (object with attribute tag 8).

No settings are available

The “Bore Symbol” drawing rule is a specially designed tool for visualizing borehole symbols and is only applicable together with the Novapoint “GEOPLOT” module.
