Is there an efficient way to produce geometry from point data using QGIS?
Each point represents a feature that may require one or more geometric primitives such as circles, curves or polylines (open or closed) to represent it.
Please note that while CAD is the best tool for creating geometry I am seeking alternative methods of achieving this using QGIS without using CAD. However the final QGIS geometry needs to be exportable to CAD in a usable format.
The goal is to produce database linked maps within QGIS but be capable of supplying useful CAD geometry to clients if they request it.
Options explored so far:
Vector > Geoprocessing Tools > Buffer
