The last operation is an intersect extrusion meant to isolate a part of a body to conduct a 3D printing test. Inside the hollow cylinder are 2 crush ribs that should have been included as part of the intersect operation but didn't. Trying to combine those ribs with the body also fails, in that the operation is successful, but the ribs remain detached.</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Ceecis_0-1690255033191.png" style="width: 600px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1244465iD99005A2735C4DE7/image-size/medium?v=v2&amp;px=400" role="button" title="Ceecis_0-1690255033191.png" alt="Ceecis_0-1690255033191.png" /></span></P><P>&nbsp;</P> Tue, 25 Jul 2023 03:18:58 GMT https://forums.autodesk.com/t5/fusion-support-forum/intersect-ignores-part-of-a-body-and-bodies-refuse-to-combine/m-p/12123801#M32724 Ceecis 2023-07-25T03:18:58Z https://forums.autodesk.com/t5/fusion-support-forum/intersect-ignores-part-of-a-body-and-bodies-refuse-to-combine/m-p/12124327#M32725 <P>Hi,</P> <P>the rips have no overlap</P> <P>&nbsp;</P> <P><div class="lia-vid-container video-embed-center"><div id="lia-vid-6331799903112w934h540r903" class="lia-video-brightcove-player-container"><video-js data-video-id="6331799903112" data-account="6057940548001" data-player="default" data-embed="default" class="vjs-fluid" controls="" data-application-id="" style="width: 100%; height: 100%;"></video-js></div><script src="https://players.brightcove.net/6057940548001/default_default/index.min.js"></script><script>(function() { var wrapper = document.getElementById('lia-vid-6331799903112w934h540r903'); var videoEl = wrapper ? wrapper.querySelector('video-js') : null; if (videoEl) { if (window.videojs) { window.videojs(videoEl).ready(function() { this.on('loadedmetadata', function() { this.el().querySelectorAll('.vjs-load-progress div[data-start]').forEach(function(bar) { bar.setAttribute('role', 'presentation'); bar.setAttribute('aria-hidden', 'true'); }); }); }); } }})();</script><a class="video-embed-link" href="https://forums.autodesk.com/t5/video/gallerypage/video-id/6331799903112">(view in My Videos)</a></div></P> <P>&nbsp;</P> <P>günther</P> Tue, 25 Jul 2023 08:57:32 GMT https://forums.autodesk.com/t5/fusion-support-forum/intersect-ignores-part-of-a-body-and-bodies-refuse-to-combine/m-p/12124327#M32725 g-andresen 2023-07-25T08:57:32Z https://forums.autodesk.com/t5/fusion-support-forum/intersect-ignores-part-of-a-body-and-bodies-refuse-to-combine/m-p/12124405#M32726 <P>Even if they do have overlaps, it is still the same bug.

Selecting the other side of the circles made to create the crush ribs is a workaround, but you're right it should work without selecting the other side.</P> Tue, 25 Jul 2023 12:47:23 GMT https://forums.autodesk.com/t5/fusion-support-forum/intersect-ignores-part-of-a-body-and-bodies-refuse-to-combine/m-p/12124810#M32728 Ceecis 2023-07-25T12:47:23Z https://forums.autodesk.com/t5/fusion-support-forum/intersect-ignores-part-of-a-body-and-bodies-refuse-to-combine/m-p/12124846#M32729 <P>Hi,</P> <BLOCKQUOTE><HR /><a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/5072782">@Ceecis</a>&nbsp;wrote:<BR /> <P>Thank you for spotting that.
