Unable to View, select or edit Viewports

Hi,

I am amending a drawing which has viewports already set up on it. the problem is that i cannot view the vieports, all layers are on, there are no frozen layers. i can select model mode and operate within the viewport as normal.

however there is no visible border to the viewport whether in model or paper space. I have selected all items and then selected viewports from the properties dialogue box and changed all viewports tot he same layer, but they still remain invisible.

does anyhone have any ideas, as this is slowly driving me mad!!!!

Thanks in advance

Using:

OS: Windows XP

Ver: AutoCAD 2007

Try saving the drawing, then running an Audit (remembering to correct any errors) at least 2 to 3 times. Then save the drawing again, and close it down.

Reopen your drawing to see if you still have the same issues.

Hi,

Thanks for your reply, I've completed 8 audits, no errors were found, still experiencing the same issues, I've not seen this before and not knowing what it is is driving me nuts!

I hate to state the obvious, but be sure the viewports are turned on.

Is it possible you could post up your drawing (or a portion of it) ?

yeah the viewports are all on as when originally selected this value varied between the 4 viewports in the drawing. I can't post the drawing unfortunately. I will keep trying and if i find the answer i will post on here. will keep checking back though in case anyone has any additional suggestions.

Thanks again guy's.

This one's got me stumped.

This drawing is definitely acting weird. I doubleclicked inside the viewport and did a VPMAX/VPMIN and the viewport came back alive. weird. I re-opened the drawing, did a Select All (Ctrl+A) and deleted the viewports then made new ones. They work.

weird stuff.....

I have seen others with this problem and it is always the result of a drawing starting in another program and being imported to AutoCAD format.

And the solution is always to redo the viewports at a minimum, sometimes having to insert the ms contents into a new drawing and rebuilding from there.

Any idea as to how or why the original viewport are behaving in this way? Because if someone intentionally set them up to behave this way I definitely want to know how they did it

Thanks again.

For some extra weirdness, don't double click in the viewport select model space from the status bar at the bottom of the cad window and then use free orbit. You rotate one view but the other remains the same on top of it. There has obviously been multiple viewports placed on top of each other, but not being able to edit them produces some strange things....

There are three viewports total.

As per rkent, this is the message I got when I tried to open it. My guess this is the problem

i found in another forum that you can open layer manager, select all layers, then turn all off and on, freeze all and unfreeze. worked for me somehow.
