measurements

[Diana Aguirre]

hi, im from Mexico and im working in my tesis with an open pit mine cloud with the facets plugin,anyway, i want to know how to draw a segment of a certain length, but i dont know if its possible since the only thing i could do is measure the distance between two points.
i hope you guys can help me, thanks!!

You have the polyline tracing tool, but once again, it only allows you to create a polyline between existing points...
