MS_GEOPRINTPREP_DGNLIBLIST - points to DGNLIB files with valid print template models. When you run the Print Preparation Placement tool, the selection list will show one node for each DGNLIB pointed to by this variable. Each node can be expanded to show the defined print templates within the DGNLIB.
For example:
MS_GEOPRINTPREP_DGNLIBLIST = D:\ProgramData\Bentley\MapEnterprise V8i\WorkSpace\Projects\Demo_XFM\Editor\templates\*.dgnlib
Will read the list of DGNLIBs in the noted folder and present the templates in the Print Prep dialog:
MS_GEOPRINTPREP_FAVORITE - When you click the yellow star, the selected template becomes the default template.
The path to the template is written to this configuration variable.
MS_GEOPRINTPREP_DGNLIB.
As we know PrintPreparation.dgnlib is an important source file, which contain the standard north arrow, the task configuration and the various text styles and element templates used by print preparation tool.
This DGNLIB is delivered in.\Program Files\Bentley\MapStandalone V8i\PrintPreparation\defaults\ (or in the corresponding folder depending on the Bentley Map edition you are using) and pointed to by the configuration variable MS_GEOPRINTPREP_DGNLIB.
