Unwanted zoom when changing to modelspace 1

[HenricC]

As you might understand from the subject I have problem with my layouts. It seems like SOME of my layouts but NOT ALL have a current setting wich makes them zoom extents whenever I change from paperspace to modelspace.(Very frustrating)

The objects in the layouts that will zoom extents can be rotated by UCS but not in the other ones.

Can I keep the scale and switch from model and paperspace freely and still be abel to rotate the objects in the modelfile by the UCS?

I don´t want to lock the display.

You need to "lock" the viewports.
One of many ways is to right click the viewport and then click on "Display Locked" and pick "Yes". Another is to put all your viewports on a layer, I use Defpoints and/or VPorts as my layers for the MViews. Then add the followoing to your Acad.lsp file:

(DEFUN C:VL ()
(COMMAND "LAYER" "THAW" "DEF*,VP*" "")
(COMMAND "MVIEW" "LOCK" "ON" "ALL" "")
(COMMAND "LAYER" "FREEZE" "DEF*,VP*" "")
)
(DEFUN C:VU ()
(COMMAND "LAYER" "THAW" "DEF*,VP*" "")
(COMMAND "MVIEW" "LOCK" "Off" "ALL" "")
(COMMAND "LAYER" "FREEZE" "DEF*,VP*" "")
)
;
(DEFUN C:VT ()
(COMMAND "LAYER" "THAW" "DEF*,VP*" "")
)
(DEFUN C:VF ()
(COMMAND "LAYER" "FREEZE" "DEF*,VP*" "")
)
;

These do Lock all Viewports, Unlock all, Freeze all and Thaw all.

Yes, I know about display locked but I don´t want to do that. Since the layouts don´t behave in the same way my guess is that there is a setting that I´m not aware of. Also I don´t want to lock the display since I want to rotate them acording to the UCS. Don´t know about the lisp but I think there is some other answer to the problem.
Thanks anyway

After searching a bit more in the forums I found a post from Juice in apr 14, 2003 on the same thing with the reply from Exit that this is a bug, but that still don´t explain why some of the layouts behave normal.

Does changing UCSFOLLOW affect anything?
Are you going from PS to MS with the mouse or keyboard? Try the keyboard.

UCSFOLLOW!!!!

I love you.

I am currently using AutoCAD LT 2002, but have seen a similar problem with the full version. Sometimes when going into a viewport, the view will zoom out or in, but reset itself after I leave the viewport. The problem is intermittant, and unrelated to the UCSFOLLOW variable.

I am guessing it is a video driver issue. Also there are some bugs in LT 2002 with the UCSFOLLOW command in regards to Viewports, where AutoCAD will often ignore the variable.

Well,
I don´t have the problem when I switch from ucsfollow 1 to 0 and thats enough for me. At least for the moment.
