style="word-wrap: break-word;">Hi all<div class=""><br class="" /></div><div class="">Is it possible to write loops in processing. I’d like to do stuff like iterate over each poly in a polygon layer, clip features from a few layers and write them to a subfolder whose name is based on the name of the polygon layer. Think of it like atlas but for data not for print compositions. Has anyone done something similar?</div><div class=""><br class="" /></div><div class="">Regards</div><div class=""><br class="" /></div><div class="">Tim</div><div class=""><br class="" /></div><div class=""><br class="" /><div class=""><span class=""><PastedGraphic-1.tiff></span><span class="HOEnZb"><font color="#888888" class=""></font><div class="" style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;
