Regarding the workflow you described at the end, do you know about
"avoiding intersection" ?

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.

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
