[Qgis-developer] Measure tool persistence.

[Matthias Kuhn]

Hi,

It is very likely that better CAD functionality will hit QGIS soon. An
approach based on the CadInput plugin [1] is being discussed [2] and
parted to core [3]. Maybe this does already provide a lot of what you need?

Best regards,
Matthias
