We recently upgraded our shop computers from eDrawings 2014 to 2016. All the personal issues aside with the layout changes everything seems to be working fine with the exception to one thing. When we hide a part and then un-hide it, in comes in without the edges shown, so in the graphics view the part looks like a blob. It does this even in wireframe mode. I tried toggling between view modes and I still cannot seem to correct it. The setup options are limited so from what I can tell there isn't anything that we can do from the users standpoint to correct the issue.
Also we checked the specs of the computers and they fall well within the requirements to run eDrawings so I don't see that being the issue either. Additionally we did a complete uninstall and reinstall just to make sure it wasn't something to do with that.
