• The target drawing file must be in session.

• A drawing or report cannot be merged into itself.

• The source drawing is removed from memory after it is merged.

• The main drawing file can contain one or more formats. Each sheet can use a different format. When a source drawing is merged into a target drawing that has a different format, the source format is not automatically replaced. You can replace the source format after the merge.

• When the source drawing to be merged contains dimensions that are the same as those of the target drawing, the system automatically removes these duplicate dimensions from the source drawing.

• When files to be merged reference a different version of the same model, the latest version in memory is used for the drawing.

• The source drawing and the target drawing must use the same drawing units.

• When the source drawing and the target drawing contain a model with the same name, even if these are different models, the model currently in session is used in the final drawing.

• After a file is merged, the Detail options from the target drawing override the setup options used by the source drawing.

• If the source drawing contains a drawing program, it is deleted during the merge. To preserve a drawing program, use the drawing that contains the drawing program as the target drawing.

• Drawing parameters in the source drawing are deleted during the merge.
