In your original message "creating wedge buffers automatically", Andrea suggested to use the algorithm in the "default" mode, setting the fields as arguments through the data-defined button next to each. No feedback yet. Have you tried his suggestions?<br><br>Regards,<br>Harrissou</div><br><br><div class="gmail_quote"><div dir="auto">Le 11 février 2024 17:12:57 GMT+01:00, Ujaval Gandhi via QGIS-User <qgis-user@lists.osgeo.org> a écrit :</div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

When I add generate_series expression and click ok, only one more row is getting added to the batch process tool. i.e.90 degree azimuth got added. 180 and 270 were not added. Is there a way that, the batch tool can read directly from the attribute table and generate the wedge buffers? The reason is; the example that I gave has only four features.But my original file has 100 features. It will be difficult to enter all 100 values manually. If the tool can pull these values from the attribute table and generate wedge buffers that will be free of errors.</div><div><br></div><div><img src="cid:c59141ae-6846-43cb-dec1-b3eb90df81f0" alt="image.png" width="253" height="131" style="margin-right: 0px;" data-surl="cid:c59141ae-6846-43cb-dec1-b3eb90df81f0"><br></div><div><br></div><div><img src="cid:38df1462-0732-4b40-b755-57668da93681" alt="image.png" width="422" height="131" style="margin-right: 0px;" data-surl="cid:38df1462-0732-4b40-b755-57668da93681"><br></div><div><br></div><div><img src="cid:d84a292e-0808-41c4-d395-b71a2345d6dc" alt="image.png" width="423" height="186" style="margin-right: 0px;" data-surl="cid:d84a292e-0808-41c4-d395-b71a2345d6dc"><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Feb 11, 2024 at 5:19 AM Ujaval Gandhi <<a href="mailto:ujaval@spatialthoughts.com" target="_blank">ujaval@spatialthoughts.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin: 0px 0px 0px 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div dir="ltr">click 'Autofill' -> Add Values by Expression and use expression generate_series(90, 270, 90)<div><br></div><div>You will get 4 layers, one for each azimuth value.
