A PTC's Creo Parametrics Configuration Settings Configuration Variables Creo Parametrics environment variables Description ecad_area_default_import Defines how imported ECAD areas are treated. Cosm_area treats imported ECAD areas as cosmetic features; 3d_volume imports ECAD areas with z- heights as a 3D enclosed quilt. ecad_board_csys_def_name Specifies the default coordinate system name add to an ECAD board being imported. If not set, the system prompts for a name. ecad_comp_csys_def_name Specifies the default coordinate system name add to an ECAD component being imported. If not set, the system prompts for a name ecad_comp_layer_map Allows layer mapping for the ECAD components import into assembly. ecad_create_hint_map Helps create an ecad_hint.map file. YES – automatically renames components, if necessary, each time the library of component outlines is imported. This does not create an ecad_hint.add file. It controls whether the ecad_hint.map file is created ecad_default_comp_height Set the default value and units for an ECAD component being imported. Units can be: inch, mil, thou, cm, mm, micron, dsu. If not set, the system uses the current components units.
