https://forums.autodesk.com/t5/autocad-forum/autocad-2016-hide-bug/m-p/5607340#M331707 <P>Preface: This does not happen in AutoCAD 2015, only in AutoCAD 2016.</P> <P>Scenario:</P> <P>1) Open drawing and type in HIDE.&nbsp; Looks fine.</P> <P>2) Immediately do a SAVE, SAVEAS, QSAVE...whichever.</P> <P>3) Then do the HIDE again.&nbsp; The wide polylines disappear.</P> <P>&nbsp;</P> <P>To understand the drawing attached, look at it in 3D and you will see that it is constructed with wide polylines above the other objects.</P> <P>&nbsp;</P> <P>Ok, I understand, a work around to get it to do right is after the SAVE, do a regen -or- enter HIDE twice in a row.&nbsp; Nonetheless, it is a bother to have to do when it wasn't doing that in 2015.&nbsp; I suspect the issue is around the change to the displaylist for the feature of "crisp lines and circles", keeping the arcs smooth.</P> <P>&nbsp;</P> <P>If anyone has a "magic button" that will set this back, please post.</P> Mon, 27 Apr 2015 15:11:42 GMT dennis 2015-04-27T15:11:42Z
