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 : https://github.com/olivierdalang/improvedpolygoncapturing Cheers, Olivier 2013/3/4 David Fawcett <[email protected]> > There is a COGO plugin for QGIS called Azimuth and Distance.
