[GIS] Splitting lines into equal segments with QGIS

equal lengthgrasslineqgissplitting

I'm attempting to split a curved (wiggle) line into equal length segments. Have used Grass's v.split which works to a degree but does not provide the output I'm after.

v.split will extract segmented lengths based on a "maximum segment length" or "maximum number of vertices in segment". So, if I want to split the line into 10 meter segments and use a maximum segment length of 10 then all my segments come up just short, e.g. 9.98, or 9.6. for individual lines, wiggle or straight.

What I want instead is given for example a 55m line: Start at one end and place a node/point every 10m along the line until it reaches the end. In the case above it would get split into 6 segments with the last segment being 5m long and all the others being 10m.

Is there a better module?

The current version of QGIS (QGIS 3.0+) has the option to Force segments to be exactly of a given length, except for the last one using v.split. v.split is accessed from the Processing Toolbox under GRASS --> Vector
