I have 3D drawing. I put camera's in several places and situations. In viewports I choosed a camera in every viewport. They work nice so long the drawing is open. When I close the drawing after saving it ofcourse. When I open it again , the viewports jump to SOUTH-EAST. and I have to rearrange the view of the cammera again. Although I used the command UCSFOLLOW to solve this, but it did not work.
PS. that happens only in the viewports which based on camera's. The views in other viewports which are not based on camer's, stay without chaning or jumping.
Any idea how to solve this?
Solved! Go to Solution.
Do you mind sending the file or part of it?
Does it also happen with a new drawing created from scratch?

Thanks for your response.
Although I used (among others) the following operations:
• Delete all layers filters.
• Delete unnecessary layers
• Delete all xrefs.
• Delete JPEG picture
• Savefidality to 0
• Savepercent to 0
• Reset scale list
• Pu all, and -pu ( for R & B)
• Begin from scratch.
• Save the file to a higher version than 2004
• Save to DXF and turn to DWG
All these did not reduce the file size (29 MB). And did not speed the file. And did not solve the problem of the viewports as I explaned previously.
What did I miss? I don't know.
I tried to send it here as e-tansmit to reduce the file size to 19 MB!! But it could not because of file size limitations.
Thank you Luciane,
The Problem is solved, in the meaning that, I believe, the reason is not in the AutoCAD, but in my PC.
I opened the file in another PC, the viewports reacted normal and stable.
I opened again the file in my PC, the problem continued. I repeated that again and again, I got the same result.
May because of the graphic card. Of another reason. Have you an idea?
My PC uses Windows 7, Ram 8 gb, Graphic card NIVIDIA.
The other PC in which the viewports responded normal, uses Window 7 Ultimate, Ram 12, and another sort graphics card.
I'll ask also the ICT-helpdesk in the company to solve it.
I am glad to know that you are on the way to find a resolution.
I think it is a good idea to check if the graphics card drivers are updated, you can download supported/certified versions from:
It may also be worth reinstalling the program, just in case.
I hope you can have this issue resovled soon, let us know if you need anything else.
I'm glad to hear that your problem is solved.
I am having exactly the same problem but mine haven't solved. I tried opening the file in 3 different PCs but to no avail.
My PC specs at home is pretty good with nvidia ge force, 64bit, 16gbRAM.
I hope there's another solution to this problem as i love using camaras but i have to stop until i find a solution.
