[Qgis-user] Coordinate Geometry capability

[Olivier Dalang]

I'm not sure I understood you need well, but there's the "Improved Polygon
Capturing" plugin, which allows to enter the distance numerically.

I developed an update to this plugin which now allows to enter the angle
numerically also (CAD-like drawing).

Unfortunately, it's still not in the plugin repo since I'm not the original
author. But in the mean time, you can find it here :

Cheers,

Olivier
