[Qgis-user] What is the r coordinate?

[Alister Hood]

Thanks, I should have found that, but was tripped up by
https://github.com/qgis/QGIS-Website/issues/961 and not reading carefully
enough.

I wondered if it was a radius, but I thought if so I would be able to type
a radius in to turn a vertex into a curve - I was mainly confused
because digitising curves doesn't work here for CompoundCurve and
MultiCurve memory layers (they are digitised as if the provider doesn't
support curves; maybe I have a plugin that is causing this problem).
Now that I've tried a CurvePolygon layer it all becomes clear.  And I see
that to convert between a vertex and a curve you select it with the node
tool and press 'o'.

Thanks.
