Hole spacing measures differently between the folded part and the flat pattern. These are holes that&nbsp;are totally unaffected by the bends.</P> <P>I'm at a loss to explain this.

So the discrepancy only exists on the drawing. Is it possible that the views are skewed ever so slightly so that visually they look ok but are really off by a tiny amount?</P> Fri, 21 Sep 2018 19:39:24 GMT https://forums.autodesk.com/t5/inventor-forum/inventor-dimensional-inaccuracies-between-folded-part-and-flat/m-p/8284897#M212934 larry_dubroff 2018-09-21T19:39:24Z https://forums.autodesk.com/t5/inventor-forum/inventor-dimensional-inaccuracies-between-folded-part-and-flat/m-p/8284958#M212935 <P>that is the issue.&nbsp;</P> <P>the work plane on the model is off horizontal by the tiniest amount.&nbsp;</P> <P>&nbsp;</P> Fri, 21 Sep 2018 19:39:39 GMT https://forums.autodesk.com/t5/inventor-forum/inventor-dimensional-inaccuracies-between-folded-part-and-flat/m-p/8284958#M212935 larry_dubroff 2018-09-21T19:39:39Z
