Detailed Description

Class derived from QgsMeshAdvancedEditing that forces mesh based on a line.

Forcing lines consist of line that the faces are forced to follow, that is edges of encountered faces have to be on theses lines.

Caller of this class has to set the line with setInputLine() before applying the edition with QgsMeshEditor::advancedEdit()

Other option has also to be set before calling QgsMeshEditor::advancedEdit()

Since: QGIS 3.22
