	There are a number of layers in TUFLOW, for example breaklines, which use both line and point inputs. This page describes the method for converting the vertices along a line to a separate point file. To perform this operation a ~~plugin~~ is ~~used.~~ ~~The~~ plugin ~~is in the repository and is called MMQGIS,~~ for more information on this plugin please see [http://michaelminn.com/linux/mmqgis/ http://michaelminn.com/linux/mmqgis/].		There are a number of layers in TUFLOW, for example breaklines, which use both line and point inputs. This page describes the method for converting the vertices along a line to a separate point file. To perform this operation, you can either use MMQGIS plugin (for more information on this plugin please see [http://michaelminn.com/linux/mmqgis/ http://michaelminn.com/linux/mmqgis/]), or the "Extract Nodes" functionality in the QGIS Geometry Tool.
