Work with a layer's attribute table — CivilCraft help

Open a layer's table from its three dots menu in the GIS layers list (Attribute table…), from Surface › More › Attribute table, or by typing ATTRIBUTES, ATTTABLE or TABLE. The table opens beside the plan and stays open while you work. Only the rows you can see are drawn, so a layer with thousands of features opens and scrolls quickly.

Sort, filter and select

Sort: click a column title. A second click reverses it, a third puts the file's order back. Empty values always stay at the bottom. Sorting only changes what you see, never the layer.
Filter: type in the filter box. An expression such as AREA > 500 and USE = 'Res' keeps the rows where it is true (the same words as the Select tab of Analyze GIS layers: =, <, like, contains, is null, in, between, and, or, not, $area, $length). Anything that is not an expression, such as oak maple, looks for those words in every column.
Select rows: click a row. Ctrl+click adds or removes one, Shift+click selects a run, and Select shown rows takes every row that passes the filter. The selected features are drawn on the plan, and a click on a feature on the plan selects its row here.
With rows selected you can Zoom to them, make a layer from the selection, and read the total area or length in the status line.

Fix values

Double-click a cell (or move to it with the arrow keys and press Enter), type the new value and press Enter. Escape leaves it as it was. A value must fit the column: numbers as numbers, dates as YYYY-MM-DD, yes/no as yes, no, true or false. A value that does not fit is refused with a sentence and nothing changes. An empty box makes the value empty. Every edit is one undo step: Undo and Redo are at the bottom of the table, and Ctrl+Z works on the plan.

Fields

Under Fields you can add a field (text, number, date or yes/no), rename one, or remove one. A new field starts empty. A rename follows through: the label field and the style by attribute of the layer move to the new name, and removing a field drops the label and style that used it. Each is one undo step that brings everything back.

Field calculator

Writes a value into every row (or only the selected rows) from the row's other fields, its geometry and a few functions. Pick an existing field or A new field… and give it a name and type. Nothing is run as code: the expression is read by a small parser with a fixed list of functions.

Group	Words
Numbers	`+ - * /`, brackets, `abs round(x, digits) floor ceil sqrt pow min max`
Text	`upper lower trim len substr(text, from, count) left right replace concat` (text goes in 'single quotes'; a field name with spaces goes in "double quotes" or [square brackets])
Choosing	`if(test, then, else)`, `coalesce(a, b, …)`, `num(x)`, `str(x)`
Dates	`year month day` of a `YYYY-MM-DD` value
Geometry	`$area $perimeter $length $x $y $vertices`, in the project's units

A result that cannot be stored in the field's type (text in a number field) is left empty and counted in the message. Dividing by zero gives an empty value. For example round($area / 43560, 2) writes acres from square feet.

Export

Export CSV saves the rows you see (after the filter and the sort) as a UTF-8 CSV file with the field names in the first line. A text that starts with =, +, - or @ gets a leading apostrophe so a spreadsheet does not run it as a formula. To save the layer itself, use Export as-built data for GIS.

Limits

The table shows the layer in a single sort order and one filter at a time. Rows cannot be added or deleted here (make a new layer from a selection instead), geometry is not edited, and a field's type cannot be changed after it is made.
