topic solid from sweep not displaying correctly in AutoCAD Forum https://forums.autodesk.com/t5/autocad-forum/solid-from-sweep-not-displaying-correctly/m-p/5529342#M338313 Some of my solids created from sweeps are not displaying correctly, see attached file.  All those shown, were created consecutively in the same way so dont see how it could be settings.  Is this just a bug?  I want all to be shown as those on the right, not the bare bones as on the left. Thanks  Thu, 05 Mar 2015 11:55:56 GMT PSmart17 2015-03-05T11:55:56Z
