I have a little problem with my zooming at best on a drawing,
when I click on this one its zoomed out to the maximum as if I had a hidden view, annotation or other (super) away from my worksheet off I checked and I am nothing of all its around,
on the other hand I realized that if I deleted my section view, it zooms in on my sheet,
You may not see anything in your drawing but check in your 3D that you don't have a component like screws or other very far away. Sometimes drag and drop can play a few tricks.
For the problem, we switched to SW2016 this week in this version the plan that had the problem on the 2014 version continues on the 2016 so the best solution is the Zoom adjust the sheet,
