Anyway, modified file is attached for you to look at as one example of how to finish it off.</STRONG></P><P><STRONG><span class="lia-inline-image-display-wrapper lia-image-align-center" image-alt="Cavity Engrave.jpg" style="width: 600px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1030562i1952CD74282E8233/image-size/medium?v=v2&amp;px=400" role="button" title="Cavity Engrave.jpg" alt="Cavity Engrave.jpg" /></span></STRONG></P><P>&nbsp;</P> Mon, 28 Feb 2022 13:55:00 GMT https://forums.autodesk.com/t5/fusion-manufacture-forum/can-anyone-help-me-hoe-to-program-the-cavity/m-p/10975301#M51071 engineguy 2022-02-28T13:55:00Z https://forums.autodesk.com/t5/fusion-manufacture-forum/can-anyone-help-me-hoe-to-program-the-cavity/m-p/10975530#M51072 <P>thank you so much for your great help , for sure i will try it and reply you soon</P> Mon, 28 Feb 2022 15:30:43 GMT https://forums.autodesk.com/t5/fusion-manufacture-forum/can-anyone-help-me-hoe-to-program-the-cavity/m-p/10975530#M51072 rajsumanth9 2022-02-28T15:30:43Z
