Hi, I have an extrusion of the sunflower but I don’t know how to “engrave” it or make an impression in the medallion. Please help! Thanks, Susansunflower for pk3.3dm (6.1 MB)
Your sunflower curves were in pretty bad shape. Lots of overlapping or open areas that made for some problem geometry when extruding them to use them as cutters for a boolean difference.
I cleaned them up into valid closed curves by joining them and rebuilding them where needed which allowed me to extrude them solid and do a successful boolean in this file. Hopefully that helps get you back on track.
