8.3. Program Defaults Reference

This chapter lists every factory default in IQcad. Use it as a quick reference when you need to know the out-of-the-box value for any setting, style, or variable. All values are applied when you create a new drawing or choose Reset to Defaults in a settings dialog.

8.3.6. Surface Styles

Standard Surface Style

Component	Colour	Weight	Notes
Border	Yellow	2	Visible by default
Triangles	Grey	1	Hidden by default
Major contours	Brown (180, 60, 0)	2	Interval: 5.0
Minor contours	Dark green (0, 140, 0)	1	Interval: 1.0
Points	Gold (255, 200, 0)	—	Hidden by default, size 3
Contour labels	—	—	Style: Contour - Standard, interval 50
Spot elevations	—	—	Style: Spot Elevation - Standard
Elevation bands	—	—	Hidden by default. Use the Elevation Bands tab in the Surface Style Editor to generate bands: set count, choose a color ramp (Green→Red, Blue→Red, Grayscale), and click Generate Bands from Surface. This opens a small dialog — a Surface dropdown lists every surface in the drawing (preselected to one already using the style being edited, else the first surface), and Min elevation / Max elevation boxes are pre-filled from that surface’s actual range. Edit either value to an exact figure before generating, or accept the surface’s own range as-is; switching the surface dropdown refills both boxes. GPU rendering provides smooth gradient interpolation between bands.
Elevation band legend	—	—	Hidden by default (ShowLegend=False). Enable per-style in the Surface Style Editor’s Elevation Bands tab.

Built-in presets:

• Standard — contours + border visible, triangles hidden

• Triangles & Contours — both triangles and contours visible

• Contours Only — border hidden

• Elevation Banding — contours + elevation bands visible (generate bands via style editor)

• Empty — all components hidden

8.3.7. Alignment Styles

PI lines	Green	1	Hidden, dashed linetype
Direction arrows	Red	—	Interval 200 m, size 2.0
Label text	White	—	Height: 2.0 mm

Built-in presets:

• Standard — centreline + ticks + PI markers + arrows

• Centreline Only — ticks, PI markers, arrows hidden

• Design Phase — centreline as CENTER linetype, PI details + PI lines visible

• Empty — all components hidden

8.3.8. Parcel Styles

8.3.10. Civil Object Layer Defaults

When civil object layers are enabled (default: on, prefix C), each civil entity automatically creates dedicated layers for its components. The following table shows all layer name patterns and their default colours. The group, suffix and colour of every component can be changed per drawing in Civil › Civil Settings… › Layers.

Surface Layers

Component	Layer Pattern	Default Colour
Geometry (TIN)	C-TOPO-{Name}	Grey
Major contours	C-TOPO-{Name}-MAJR	Brown (180, 60, 0)
Minor contours	C-TOPO-{Name}-MINR	Dark green (0, 140, 0)
Boundary	C-TOPO-{Name}-BNDY	Yellow
Breakline	C-TOPO-{Name}-BRKL	Magenta (255, 0, 255)
Points	C-TOPO-{Name}-PNTS	Gold (255, 200, 0)
Labels	C-TOPO-{Name}-LABL	White
Spot elevations	C-TOPO-{Name}-SPOT	Cyan

Alignment Layers

Component	Layer Pattern	Default Colour
Centreline	C-ROAD-{Name}	Red
PI markers	C-ROAD-{Name}-PI	Magenta
Labels	C-ROAD-{Name}-LABL	White
Offset axis	C-ROAD-{Name}-OAX	Lilac (210, 170, 255)

Profile View Layers

Component	Layer Pattern	Default Colour
Grid	C-PROF-{Name}	Dark grey (60, 60, 60)
Axis	C-PROF-{Name}-AXIS	White
Title	C-PROF-{Name}-TITL	White
Existing profile	C-PROF-{Name}-PROF	Green (0, 160, 0)
Design profile	C-PROF-{Name}-DSGN	Red

Parcel Layers

Component	Layer Pattern	Default Colour

Fill	C-PROP-{Name}-FILL	Light pink (255, 200, 255)
Labels	C-PROP-{Name}-LABL	White
Segment labels	C-PROP-{Name}-SEGL	Cyan

Survey Point Layers

Component	Layer Pattern	Default Colour

Labels	C-PNTS-LABL	White

Section View Layers

Component	Layer Pattern	Default Colour
Grid	C-SECT-{Name}	Dark grey (60, 60, 60)
Axis	C-SECT-{Name}-AXIS	White
Section lines	C-SECT-{Name}-SECT	Green (0, 160, 0)

Point Cloud Section Sheet Layers

Component	Layer Pattern	Default Colour
Sheet geometry (frame, axis guides, trace polylines, labels)	C-PCSC-{Name}	Yellow

Every visual element painted by TAECC_PointCloudSectionSheet — the cell frames, the optional vertical/horizontal axis guides, the section trace polylines, the cell labels and the optional cell fill — defaults to ByLayer in the style entity, so all of them inherit the layer’s colour. Override an individual element’s colour via the PC Section Sheet Style editor when you need to break out of ByLayer (for example, a contrasting trace colour against a coloured frame).

8.3.11. Civil Label Styles

All label styles use paper-mm text height, scaled by the civil drawing scale.

Built-in Label Styles

Name	Height (mm)	Placement	Components
Point - Standard	2.0	Anchor TR	Number, Elevation
Point - Full	1.5	Anchor TR	Number, E, N, Elevation, Description
Point - Number Only	2.0	Anchor TR	Number
Point - Elevation Only	2.0	Anchor TR	Elevation (%.2f)
Point - No Label	—	—	Hidden
Contour - Standard	2.0	Linear aligned	Elevation (%.1f), uphill readable
Contour - Horizontal	2.0	Linear horizontal	Elevation (%.1f)
Spot Elevation - Standard	1.5	Anchor TR	Elevation (%.2f)
DR - Standard	1.5	Linear perpendicular	Deviation (%.1f cm)
DR - Millimeters	1.5	Linear perpendicular	Deviation (%.0f mm)
Station - Standard	2.0	Linear perpendicular	Station chainage
PI - Standard	1.5	Anchor TR	Station, Radius, Deflection

The Tunnel category provides label styles for deviation (DR) labels on tunnel section lines. The two built-in presets are:

• DR - Standard — deviation value in centimetres (%.1f cm), placed perpendicular to the measured profile line.

• DR - Millimeters — deviation value in millimetres (%.0f mm), placed perpendicular to the measured profile line.
