cause the model is solid and no gaps in it .</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Screenshot (100).png" style="width: 999px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1108491i10576C7E771E3AAF/image-size/large?v=v2&amp;px=999" role="button" title="Screenshot (100).png" alt="Screenshot (100).png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Screenshot (101).png" style="width: 999px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1108492i915390F23C49C0A8/image-size/large?v=v2&amp;px=999" role="button" title="Screenshot (101).png" alt="Screenshot (101).png" /></span></P> Fri, 26 Aug 2022 13:36:29 GMT https://forums.autodesk.com/t5/powermill-forum/how-to-use-3d-offset-finishing-on-multi-axis-with-multiple/m-p/11383202#M5555 hamed.desighn 2022-08-26T13:36:29Z https://forums.autodesk.com/t5/powermill-forum/how-to-use-3d-offset-finishing-on-multi-axis-with-multiple/m-p/11383244#M5556 <P>undercut means part of model is hidden by other part and cannot be seen if you view from the top.&nbsp;</P> Fri, 26 Aug 2022 13:56:58 GMT https://forums.autodesk.com/t5/powermill-forum/how-to-use-3d-offset-finishing-on-multi-axis-with-multiple/m-p/11383244#M5556 jianhua.fan 2022-08-26T13:56:58Z https://forums.autodesk.com/t5/powermill-forum/how-to-use-3d-offset-finishing-on-multi-axis-with-multiple/m-p/11383296#M5557 <P>What would i do then ?
