Use this dialog box to select a source drawing or template to compare with the current drawing, and to specify how to resolve the differences between the styles and settings.
Source Drawing Or Template
- Filename Path
-
Specifies the drawing (DWG) or template (DWT) from which to import the styles and settings. Click Browse and select the file, or enter the filename directly.
Style List
- Style List Tree Control
-
After you select the source file, the dialog box is updated to show which styles in the selected source file are different than the styles in the current drawing.
Styles are organized into collections which show whether they can be added, updated, or deleted so that the current drawing will match the source drawing or template. Click the check boxes in the tree control to change the selection of styles, or use the style list icons to change the selection.
- Grayed Out List Entries
-
If a style is currently in use, it cannot be deleted and is grayed out in the list.
If a style is referenced by other styles or settings that are selected to be imported, it is selected by default and cannot be unselected.
