Yes, drawing extraction templates in AECOsim SS6 US dataset, for instance, are stored in C:\ProgramData\Bentley\AECOsimBuildingDesigner V8i Ss6\WorkSpace\BuildingDatasets\Dataset_US\seed\DEM_templates\ folder..By default drawing extraction uses DEM_Templates_Architectural.dgn as a template, but you could add one of your dgn files with drawing extraction definition settings and use the configuration variables to locate it.If TFBXS_SEEDFILE points to a design file located in the dataset seed directory and the file has several section definitions in it, Drawing Extraction will use the section definition defined by TFBXS_DEFNAME for the template to create a new section definition.Otherwise, if TFBXS_DEFNAME is not set, a Section Template list box with all the section names in it will pop up to choose one as the seed for creating a new section definition.
