Help! Blank Revit 3d View (Suddenly)

[alexpapado1821]

I got a blank 3d view. This is like the 3rd or 4th time that happens to me with the same model. The story goes like this.

I have almost completed the 3d steel structure and I need to add some connections. Suddenly I switch to 3d view and I can't do anything (zoom, draw etc). I close and reopen and the 3d view is blank. 

I open a previously saved model, try to add some connections, same result.

I tried the usual recommendations (ZA, hardware acceleration off, phasing, etc) with no luck. 

I tried to open it with LT and I'm still getting a blank 3d view.

Structural Plans are also blank, Elevations and Sections are still working.

Here is the link of the file.

I've had this happen a few times over a dozen years.  I find that if you create a NEW local file in an entirely different directory...no longer an issue.  And of course, check your worksets are all open, sometimes they are just NOT after opening a model.

@twebb4CYQY : Do you mean that I should save it in a new location?

I had this happen on one model where the Revit file size in the same but nothing was visible anywhere. What worked for me was, that I created a detached model using transmit from Tab ADd ins. And made that newly detached file to be a new central. Now creating a new local worked for me.
