[QGIS-Developer] Geoprocessing Tools Fail with Memory Layers

I've asked about this several time and have never gotten a real response. The following code creates two memory layer polygons that overlap. from qgis.core import (QgsFeature, QgsVectorLayer, QgsPoint, QgsFeature, QgsMapLayerRegistry) poly1 = QgsVectorLayer("Polygon?crs=epsg:4326", "Polyg

Hi Martin, > Yes it is a known issue: https://issues.qgis.org/issues/17493 Thanks. I wasn’t aware a ticket had already been opened. Sorry for the noise, but then you know now it also plagues OS X and is not solved in Qt 5.10, apparently. Cheers, have a nice weekend! Vincent

[QGIS-Developer] Learning the node tool in 2.99

Hi, I'm sure we had this discussion in the past but couldn't find a discussion with outcomes. I'm doing some digitizing these days, using master and still fail to know how i should proceed for some actions: - how do I add a simple vertex on a line? with the click-click system, it wants me to move

[QGIS-Developer] QGis 3D performance

Folks, sorry if I bug you with my multiple (scattershot) messages. When I display a 3D view on OS X / Qt 5.10 with a reasonably recent MacBook Pro 13" (i5-5257U CPU - integrated graphics), even when I don’t interact with the view, the fan ramps up and top reports a CPU usage around 50% for QGis

[QGIS-Developer] QGIS 3D: Support for 3DM (x,y,z,m)

Is it correct that the 3D engine currently does not understand measurement values in 3DM format. When having four numbers in a coordinate the z (and m) value is skipped rendering the geometry af terrain = 0 meter (any 2d layer in 3D map is default rendered at z=0). Example: /SELECT 1 AS
