Keep the following points in mind when you open drawings from earlier releases:
- To upgrade a drawing from an earlier release to the current release, open the legacy drawing and then save the drawing. When you open a drawing from a previous release in a newer one, a task dialog box appears prompting you to do so. If the drawing references other legacy drawings, open and save those externally referenced (xref) drawings to upgrade them to the current release.
- If you try to edit an external reference drawing within a legacy drawing, you are prompted to update the external reference drawing to the current release. It is recommended that you use the same version for your external references and host drawings.
- If you open a legacy drawing in the Style Manager, the drawing is marked as read-only; you can copy styles from that drawing to drawings in newer current versions. If you copy styles from the current version to legacy drawing, you have to save the legacy drawing under a new name and in the current release file format.
- Open and save a legacy drawing in the current version if you want to be able to edit it in DesignCenter
.
Attention: Any time you combine a drawing from a previous version with a drawing from the current version, you should first open the previous version drawing and save it. For example, before inserting a drawing as a block or attaching it as an xref, open the drawing and save it to promote all the objects to the current version.
