This may be a fairly simple fix, but I'm stumped at the moment. I have a drawing from a class I took in 2011 and want to add a portion of it to my portfolio, but when I open it in AutoCAD 2015, zoom to the area I want to use and create a new layout in paper space, the viewport automaticallyzooms way in and I can't get it to zoom out. Also tried zoom extants before switching to paper space with the same result, so I can't even get a layout of the whole drawing.
Attached is a screen cap to show what I mean (Look closely and you can see segments of a line and an arc). I also have AutoCAD 2014 for Mac and the same problem occurs there. It's the first time I have tried to open an older (relatively) file in either version, so does anyone have some idea what I'm missing? Thanks.
