[Qgis-developer] more advanced editing tools

[Bernhard Ströbl]

Hi Leyan,

I know "avoid intersection" and it works ok but having several layers as 
digitizing base and creating a new polygon it is not very handy (open 
menu untick what is ticked, tick what you need now, digitize the 
polygon). It seems more straight-forward (especially from a user's point 
of view) to copy a polygon from a base layer (e.g. parcels) into your 
edit layer, select a polygon/line in another layer, activate your edit 
layer again and click on a "clip" button. More convenient would be 
Giovannis "fill space" option.
Regarding cadTools I would expect CAD-like functions in there, i.e. 
construction things, clipping, saving all layers etc. do IMHO not really 
fit to CAD.

Are there any other editTools around?
