Use the Auto-renumbering option to number lines with new, consecutive numbers, for example when calculation lines are no longer numbered correctly because you have added new calculation lines. All lines will be renumbered. You can, however, also choose to start the renumbering process for the part calculation lines or engineering BOM lines from a particular line.
Example
Let us assume you want to renumber all calculation lines, starting with 10 and continuing with 20, 30, etcetera. In that case, you would choose 'All lines', a starting value of '0' and a step size of '10'.
For each calculation line you can choose to display phantom lines on the form. Select the Also number invisible phantom lines check box to include non-visible phantom lines when renumbering the lines:
If you leave this check box empty, only visible calculation lines will be numbered consecutively. The visible phantom lines are taken into account in the numbering, and the non-visible phantom lines are ignored (the non-visible phantom lines are assigned a negative number). You will see a set of consecutive numbers on the form. In the example below, the numbers are 10, 20 and 30.
If you select the check box, all calculation lines are numbered consecutively. If they contain non-visible phantom lines, you will see that numbers are skipped on the form. The non-visible phantom lines are numbered consecutively, but are not displayed on the form. If the calculation contains non-visible phantom lines, you will see non-consecutive numbers on the form. In the example below, the numbers are 10, 30 and 40.
