[mch2021-terrain] Helping at team terrain

[rowan8k]

Hey Bart and others!

Sorry to let you know so late but I've got my hands full with merch and other things right now.
I don't want to commit to something I cannot guarantee I will be able to fully commit to.

Wanted to join the meeting tonight to let you know but I'm not feeling so well.
Wish you all the best!


Best,

Rowan

But as far as I can tell you need to go to the advanced digitizing menu, which is hard to find for a beginner. There are no keyboard shortcuts for these operations unless you set them yourself.

Specifically, although you can do mapping in Qgis, it doesn't seem to be designed for designing new areas (but rather for documenting existing places). If you have more experience with QGIS and disagree with this statement, we would love to discuss with you.
