Text Commands¶

R3Survey provides a set of commands for quickly inserting survey text at standard sizes and for modifying existing text in the drawing.

Text height is automatically scaled based on the drawing scale set by R3DWGSCALE. This ensures plotted text is a consistent size regardless of the model-space scale.

Text entry commands¶

These commands place single-line text at standard survey sizes. The size refers to the plotted height in millimetres — the model-space height is calculated as:

Model space height = (Drawing Scale × Text Height mm) / 1000

Command	Plotted height	Default layer
`T0`	2.2 mm	TEXT0
`T1`	2.5 mm	TEXT1
`T2`	3.5 mm	TEXT2
`T3`	5.0 mm	TEXT3
`T4`	7.5 mm	TEXT4

By default, text is placed on a predefined layer (TEXT0–TEXT4). If USECURRENTTEXTLAYER is enabled, text is placed on the active drawing layer instead.

Toggling text layer behaviour¶

Type ToggleTextLayer to switch between predefined layers and the current layer. The current state is shown in the command line.

Annotative text

T0–T4 are designed for non-annotative workflows. If your drawing uses annotative text styles, AutoCAD controls the display scaling independently. Confirm results against your office drafting standards.

Text modification commands¶

Command	Description
`R3ADDPREFIX`	Adds a prefix to selected text
`R3ADDSUFFIX`	Adds a suffix to selected text
`R3ADDSPACESTOTEXT`	Adds additional spacing between words
`R3REMOVESPACESFROMTEXT`	Removes extra spaces from text
`R3ADDBRACKETSTOTEXT`	Wraps selected text in brackets
`R3ALIGNTEXTTOLINE` / `R3ALT`	Rotates text to align with a selected line or polyline segment
`R3SPLITTEXT`	Splits a text string into individual word entities

R3ALIGNTEXTTOLINE / R3ALT¶

Rotates text to match the angle of a selected line or polyline segment.

Type R3ALT (or R3ALIGNTEXTTOLINE)
Select a line or click on a polyline segment — the segment is detected automatically from your pick point
Select text entities to align — each one is rotated to match the line angle
Pick the same text again to flip it 180°
Press Esc to select a different line, or Esc again to exit
