Hello, I'm working on a Python plugin with 3D features. But I have some issues with the available methods.
What I'm doing : - layer->startEditing, to set the layer editable if it's not yet the case (asking the user to do it) - feature->geometry->geometry, to have the 3D geometry for my feature - then I manipulate the geometry - layer->changeGeometry, to update the geometry of my feature Until the, It works fine... - I keep my layer editable, and try to do the same with another feature - but : I can do feature->geometry, but feature->geometry->geometry give me "Access violation - no RTTI data!" - and if I add updateExtents + commitChanges to save my layer, and try to do the same again, the feature->geometry->geometry leads to a mini dump Anyone to explain to me what's going on ? Thanks for the answer, Christophe Gusthiot
