The "Exchange parts" functionality replaces the part of a 3D part placement (enclosure) and in the process replaces the 3D graphical macro of the original enclosure by the graphical macro of the other part. This can be necessary if the 3D graphical macro has been revised or if a larger or smaller enclosure is required for the existing mounting layout.

The exchange of the part allows enclosures to be replaced by other enclosures in a single pass. It is no longer necessary to search for, delete and once more place all the existing 3D graphical macros in the layout space.

• All the properties as well as the existing equipment of the original enclosure are transferred completely and graphically unchanged to the new enclosure. The accessories of the original enclosure are transferred if these also exist as accessories of the new enclosure. Accessories that were not transferred have to be inserted manually by the user.
• Differences that occur after the exchange (for example by modified size ratios or gaps in a line up) have to be corrected by the user.
• Objects that cannot be placed in the new enclosure are displayed on the "Incorrectly placed" hierarchy level directly under the "Enclosure" hierarchy level. These objects can be placed manually by the user on a mounting surface of the new enclosure. After a correct new placement the "Incorrectly placed" hierarchy level is removed again.
• If the 3D macro stored at the new enclosure part has several macro variants, you can select one of these variants before carrying out the exchange (for example enclosure with door hinge right or left). This makes it possible to implement different types of construction not through a complex modification of the placed enclosure part, but rather to plan them directly in the master data.

Preconditions:

• You have opened a project.
• The layout space navigator is open and a layout space is open.
• You have marked at least one enclosure in the layout space navigator.

1. Select the Exchange parts popup menu item.
2. Select the desired enclosure part in the Part selection dialog. Click [OK].
3. In the dialog Select macro variant select the variant of the 3D macro that is to be used during replacing. Click [OK].
   
   The original enclosure is replaced by the new enclosure part.
   
   The part placements from the original enclosure are placed at the same position in the new enclosure.
   
   Errors which occurred during the exchange are displayed in a message (for example assignment to mounting surfaces that was not possible, accessories that were not transferred, etc.).
   
   If accessories that do not exist in the new enclosure could not be transferred, this is displayed in a system message.
4. Use the Check run 026103 to determine part placements whose mounting surface does not exist in the migrated enclosure. These objects are displayed in the layout space navigator under the hierarchy level "Incorrectly placed". For the correction incorrectly placed part placements must be placed manually on the existing mounting surfaces.
