Re: [Qgis-user] Using expression dialog to access attributes from a relation.

Hi Andrew, you can use the relation_aggregate expression to concatenate the child items, something like: relation_aggregate('my_relation','concatenate', "child_attribute", concatenator:=',') just see the help for relation_aggregate in the expression builder. bests regards Stefan --- Mit

Re: [Qgis-user] looking for mapping program

Hi Diane, some thoughts to your question: QGIS would be a very good choice (or the best!) and will be a substainable GIS for your company. You are writing that there is only a txt export option? A quick view on the user guide (http://static.garmin.com/pumac/XMap7Manual.pdf) shows, that xmap

Re: [Qgis-user] Drill hole section with QGIS 3

The gis representation of a drill hole is normaly a point with some stratigraphic or lithological information of the underground behind it (a 1:n relation, 1 drill = n strata). In qgis2 there was the midvatten plugin which does such drill hole sections (see attached image). hope this makes

Re: [Qgis-user] Qgis 3 where is 3D View?

Hi Alessio, the Ubuntu QGIS3 is not compiled with 3D support due to an outdated Qt version (Ubuntu 16.04 comes with Qt version 5.5). I think you have to build QGIS by yourself and update the Qt version before. From Lutra Consulting there is a brief description how to do that:
