Hi, Yes the easiest way is to densify your polygons. With the desify algo you can do this and specify how dense you want them to be. processing.run("native:densifygeometries", {'INPUT':'C:\\Users\\reginaldc\\Documents\\testdensify.gpkg|layername=testdensify','VERTICES':1000,'OUTPUT':'TEMPORARY_OUTPUT'}) Next you can create a line from your polygon. This line will contain the same amount of vertexes as your polygon. processing.run("native:polygonstolines", {'INPUT':'memory://Polygon?crs=EPSG:31370&field=fid:long(0,0)&uid={8ed5e288-ec55-4630-aaf8-8f26a1e1c5cc}','OUTPUT':'TEMPORARY_OUTPUT'}) Next you create points from your line. processing.run("native:extractvertices", {'INPUT':'memory://MultiLineString?crs=EPSG:31370&field=fid:long(0,0)&uid={1b672349-4d50-44b6-b4b4-98bb6218d3ce}','OUTPUT':'TEMPORARY_OUTPUT'}) Then you look for the distance of the closest vertex processing.run("qgis:distancetonearesthubpoints", {'INPUT':'C:\\Users\\reginaldc\\Documents\\testdensify.gpkg|layername=testpunten','HUBS':'memory://Point?crs=EPSG:31370&field=fid:long(0,0)&field=vertex_index:integer(10,0)&field=vertex_part:integer(10,0)&field=vertex_part_index:integer(10,0)&field=distance:double(20,14)&field=angle:double(20,14)&uid={629995db-9019-47f2-9c4b-72523ff6fc9e}','FIELD':'vertex_index','UNIT':0,'OUTPUT':'TEMPORARY_OUTPUT'}) Finally you make a buffer a little bit greater than this distance in the direction of the closest vertex (angle is also in the attribute table.
