Hi: 

This seems to be a bug in WinBUGS. The doodle shrinks when the .odc 
file is reopened. And the  Scale Model  option in the  Doodle  menu
cannot expand (input < 100% works; input >100% has no effect). Below 
is one suggestion from Samu. Here is another:

1. Open the .odc file. (The doodle will be unreadable.)
2. Select the doodle by doing  Cnrtl-Space.
3. Expand the doodle to window width. This is done by dragging the 
   highlighted right edge of the doodle to the right. What happens 
   is that the width becomes window width (of course) but the height
   shrinks. So for e.g. in an 10x10 window you go from 3x3 in the 
   top left corner to 0.5x10. However the font is readable now. This
   you can see easily if say one node is selected and so its 
   description appears at the top.
4. Go to  Tools  . Select  Document Size  . Select  Window Width 
   and  Window Height  . You get a readable doodle. 

Saving this document is of no use. When you reopen it you have to do 
thru the above resizing exercise all over again. But it takes only a 
couple of seconds ... .

Regards.

Roy

I am afraid that there is no simple answer, it seems that this is one of the
bugs in WinBUGS...

I have had similar problems with large doodles. I am building models with
hundreds of nodes and I have tried many ways to save the doodle so that it
will not resize(shrink) itself when opened. Following procedure has helped
me out from this situation:

1. Create a SMALL doodle, create only few nodes
2. Copy the doodle to the clipboard
3. Create a new document
4. Set the new document size to be fixed and very large.
5. Paste the small doodle to the large document
6. Resize the doodle by dragging from the corner of the selection.
7. Scale the doodle so that nodes and fonts are smaller but still readable.
8. You may need to repeat steps 6 and 7 successively in order to have enough
space to your model.
9. Now start defining your model by drawing nodes etc.
10. When you save and then open this document including the doodle, the
doodle should open at same size.

This is a very frustrating way to avoid the problem, because you can scale
the doodle too much by accident, and then the font size is again too small.
So you may need to do the whole procedure many times until you are
satisfied...

Furthermore, there seems to be a limit in resizing the doodle in large
document. You can not have a doodle which is near the size of the large
document.

If someone sends you a better solution, please inform me !

I really hope that the next version of winbugs fixes this problem also.

Samu
