Field calculator

Numeric fields contain simple calculator supporting four basic operations: addition, subtraction, multiplication and division.

For example, increasing field value by four can be achieved by writing "+4" at the end of the value and pressing enter.

Examples:

12+2 -> 14

12-2 -> 10

12*2 -> 24

12/2 -> 6

Formulas

Values can also be modified by formulas starting with the equal character (=) and followed by some operation and value.

For example, value "=+2.5" in the Z-coordinate field adds 2.5 metres to the active point.
