Problem

Print preview timeout expiration error.

When opening the print/plot dialog in a complex model, I keep getting the error "The print preview did not complete due to timeout expiration". 

Solution

This is most likely due to the configuration variable:

By default this variable is set to a value of ten seconds, so if the preview would take longer than that to complete, you will get this warning message. In order to avoid the message, simply set the value for a hight number. For example 30, or whatever might accommodate the needs of the DGN file you are plotting. 

For V8i:

 MS_PLT_THUMBNAIL_PREVIEW_TIMEOUT. 

For CONNECT Edition:

MS_PLTDLG_THUMBNAIL_PREVIEW_TIMEOUT
