- Make sure there is an active Spreadsheet open so that the button is enabled.
- Select a cell.
- Press the Spreadsheet SetAlias button.
- Enter an alias:
- Only alphanumeric characters and underscores (
A
to Z
, a
to z
, 0
to 9
and _
) are allowed.
- The first character must be a letter.
- Using 1 or 2 capital letters followed by 1 to 5 numbers, for example
AB123
, is not allowed as this is considered a cell address.
- Character sequences that are units are not allowed. For example
W
is an invalid alias as it is the unit for Watt. Since FreeCAD supports many units it is best to avoid short aliases. See Expressions.
- Using the mathematical constants
pi
and e
as aliases will lead to errors and should be avoided.
- Do not use spaces in aliases as they will also lead to errors.
