[GRASS-user] digitizer

[Martin Album Ytre-Eide]

Hello all.

I have been trying the digitizer in 6.4.2, and I am having several difficulties. I am working with a polygon map, and as a test, I am trying to create a polygon which I try split into four smaller polygons. First I divide it in half and then a divide one of the new halves in two. Afterwards, I have generated centroids for the area. I have used only the "new boundary" tool for this - and that may be wrong? But I have tried some other options without any luck.

Does anyone know how to do this? There also seems to be a problem that the map is saved even though I say no thanks. So, if you do a mistake - it could be hard to fix - is there an undo function in an other version?

Thanks!

Martin
