Revit 2016 Render stuck at 99% for 5 hours

[Anonymous]

I've been rendering an elevation using a 3D view in Revit 2016 for about 27 hours already. It's been stuck at 99% for the past 5 or 6 hours.. I've rendered heavier files before and it's the first time this has happened. Setting is at High, screen resolution of 1136 pixels by 191 pixels. There are two boxes left unrendered and it doesnt seem to be progressing at all. Has anyone else had this issue? Thanks in advance!

hello 

it might be a problem of graphic card that need to rest and to cool down again but the problem i faced it before is that when revit stack to a percentage the only issue that you can do is to stop the rendering to save the picture than crop it again . 

thank you , regards
