https://forums.autodesk.com/t5/fusion-design-validate-document/ghost-lines-after-combine-function/m-p/5799874#M287262 <P>Thanks Jeff!&nbsp; I'm really learning a lot!&nbsp; However, I should have probably started with an easier design for my first 3D project.</P><P>&nbsp;</P><P>I've attached some pics to show the issue better.&nbsp; I used a sketch to cut two bodies and then combine them into one.&nbsp; I had perfect alignment.</P><P>Now that they're one body they still have multiple faces.&nbsp; It's the areas where the faces meet that have the white lines.&nbsp; I tried to stitch them together in Patch but when I select "Stitch" they are no longer selectable. Is that the only way to combine these faces into one?</P><P>&nbsp;</P><P>I think they are so minute that they will fall way below my CNC tolerance but they are annoying and I would like to fix them just in case.</P> Wed, 02 Sep 2015 14:45:02 GMT TOwens777 2015-09-02T14:45:02Z
