Infatti, è molto probabile che abbia usato il link "QGIS Desktop 3.16.4"
invece che "QGIS Desktop 3.16.4 with GRASS 7.8.5".
Quali errori o avvisi vengono riportati nel pannello dei messaggi di log?
Hi Kirk,
Indeed, converting to vector and styling it using rule-based styling is an
option. Having contour renderer for raster will avoid extra processing and
data conversion.
With contour rendering of raster, you can also use "Resampling" for
creating smooth contours on the fly.
@Azzura,
Hi Sebastian great, it works, thank you.

Bernd,
Thanks for the hint.
The % operator description in QGIS only says: Remainder of division
This has thrown me off in the past because I have tried to search for the
Modulo in the expressions dialog and nothing came up.
I should probably request a change to add the modulo term at the QGIS git
Dear Saber,
thanks a lot.
I imagine in this case it is not possible to insert the labels of elevation.
Thanks a lot, Azzurra

In case someone wants to google for the " % " later: it's called modulo
operator (damn, took me half an hour to remember that)

Hi Saber:
You can do this directly in symbology. See link below, Use Rule Based
Symbology and "Elev" % 100= 0 to separate all the contours that are
multiples of 100. Set your line symbols and you should be good to go.

I use rule based styling with this expression for my 100m contour filter
rule:
"ELEV" % 100 = 0
And then another rule that has the Else selected.
The formula is:
"ELEV" :The attribute field that contains your label
% : The remainder from division
100 : the divider
= 0 : the remainder should equal
Hi Azzurra,
You can use Raster styling to display it as contours with minor and major
contours:

Kind regards

Hi to all,
I have extracted contours from a dtm raster 20 m resolution file and the
result is a vector file of contours with 20 m of interval between the
contours.
I would like to have two different symbols for these contours: for example
black colour and thickness 1 for the contours with
Hi Calvin,
This is an old issue, see this GIS Stack Exchange question from 7 years ago,
Underdark gives a good work

Dear Aloisio,
if I understand you right, you have added a scale bar via menu "View" >

to your Map View and then your map view scale changed. Tried it with my
3.14.16 version of QGIS and the map scale doesn't change with switching on
or of the map view scale bar as a
