The program merges the elements to create a new element. The new element is given the name that you just entered.

A progress bar shows the progress while the fill is being carried out. If you click the progress bar’s [Cancel] button, the program suspends fill processing and displays a dialog showing results up to that moment.

Memo

The program retains the fill data generated up to the time when you clicked the [Cancel] button. If you wish to resume the fill operation, click the [All] button. Filling will then continue from the hole at which the operation was suspended.
