Hi Jérémie,

Do you have geometry simplification turned off? See "Settings" --> "Options" --> "Rendering" --> "Enable feature simplification ..."

Make sure this is deactivated (I think it is enabled by default).

Greetings,

Andreas

Tested too fast :(

Behavior is ok when zooming in, but still problems when zooming out (whereas the entire feature is visible !).

Circles should follow the strokes generated with the tool "Points along geometry".

Hi,

Thank you very much Nyall, this one was pretty well hidden.

With clipping unchecked, behavior is as expected for my use case.

Hi,

I'm using QGIS 3.10.

I tried to use only symbology to display a stroke every km along a road.
The project CRS is 2154 (Lambert 93).

When adding a ""symbol line" with an interval of 1000 map units (meter for 2154) - or 1000 meters at scale, same result - I achieve to display symbols every km.

Problem is when I move the map or change scale, the symbols do not always stay in place. They are sometimes misplaced.

I've been told that problem can be that the first node of the line is not always the reference to calculate the intervals.

From the bottom of the symbol widget, click the "Advanced" button and
uncheck "Clip features to canvas extent".

You can find a GIF here that displays my problem : https://zupimages.net/viewer.php?id=21/02/nvr2.gif

Circles are symbols via Symbology.
Strokes are symbos on points generated vith the tool "Points along geometry".

You can see that circles are not always at the same place as the strokes.

Is it a "normal" behavior ?
Anyway as a user I would expect that symbols are always generated at the same place from the starting node.

Thanks for your enlightments on this.

Jérémie.
