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?

This is much easier to use than snapping points, and it works across
different layers.

Regarding the more advanced digitization features, I think the best
would be to improve CAD tools instead of creating yet another plugin
that people will not find. I agree that these features are important.
One I would like is to see the distance and angle directly during
digitizing, while you enter a line.

Regards,

Leyan

Dear list,

during a course I realized that my institution needs some more editing
tools for advanced editing tasks e.g.
- prolong a line
- cut polygon with feature (line or polygon) from another layer
- save all layers being in editing mode in one go
- some more

A little background: when digitizing data we are not starting from
scratch but are digitzing on existing data in many different layers
(parcels, restricted areas ...). A new polygon normally needs to fit
into these existing boundaries. Trying to digitize along existing
boundaries of several layers and snapping to them is cumbersome and
you are very likely missing snapping nodes (even when using trace
digitize plugin).

Is any of you aware of similar functions in a plugin (I know
cadTools)? Is anyone interested in joining me to create such tools as
a Python plugin? Which functions would you like to have?

regards

Bernhard
