The dialog box contains data about the possibility to perform the operation of transforming an area feature to a line one, and when it is impossible to perform the transformation displays a short description of the reason for it.
The checkbox Remove source feature denotes whether it is necessary to remove the source area feature when creating a line feature or the source feature should be retained.
The checkbox Complete boundary permits indicating if the obtained line feature should be a closed or opened polyline. If this box is cleared, when transforming boundaries of an area feature the edge which connects the last vertex with the first vertex from the ones built when entering this boundary will be excluded from each boundary.
If the area feature being transformed has inner boundaries, a separate line feature will be created from each boundary.
