Yet as soon as I got to that point I soon realized my model wasn't solid. Any fixes to this without filling in the holes? (I can always re cut the holes) Thanks!</P> Wed, 25 Nov 2020 04:24:22 GMT https://forums.autodesk.com/t5/fusion-support-forum/can-t-convert-surface-body-to-solid-body/m-p/9893801#M97109 Anonymous 2020-11-25T04:24:22Z https://forums.autodesk.com/t5/fusion-support-forum/can-t-convert-surface-body-to-solid-body/m-p/9894615#M97110 <P>Can you File&gt;Export your *.f3d file to your local drive and then Attach it here to a Reply?</P> Wed, 25 Nov 2020 12:46:13 GMT https://forums.autodesk.com/t5/fusion-support-forum/can-t-convert-surface-body-to-solid-body/m-p/9894615#M97110 TheCADWhisperer 2020-11-25T12:46:13Z https://forums.autodesk.com/t5/fusion-support-forum/can-t-convert-surface-body-to-solid-body/m-p/9896032#M97111 <P>Sorry man I don't think I can do that since I doubt he wants the file out for free. But is there any other way I can make the body solid before putting holes in it? So that when I do they'll be solid?
