[GIS] Creating Minimum Convex polygon around points in QGIS

Question

I just downloaded QGIS 3.0.2 and trying to create a minimum convex polygon around points using the "Minimum bounding geometry" (convex hull).

The videos and help documents I see online appear to be from older editions of QGIS. I cannot find comparable menu options in this edition.

Can this be done in this version of QGIS?

Answer 1

I had no problem with the convex hull (vector > geoprocessing tools > convex hull) of QGIS 2. It used to make a convex hull around a set of points immediately. In QGIS 3, the same raises the error "Cannot calculate convex hull for a single Point feature (try 'Minimum bounding geometry' algorithm instead)."

Greg gave the answer (toolbox -> Vector Geometry -> Minimum Bounding Geometry):

In the drop box "Geometry type", choose "Convex hull".
