Using XRefs

You can place a document (drawing file or NDW-format file) as an XRef in a document as often as you need. This way, you do not have to enter the same elements again and again, such as the furniture of hotel rooms. All you need to do is create the elements once in a document. Then you can insert this document as an XRef as often as you want. Changes to the original data only need to be done once - all associated XRefs will update dynamically. XRefs can be inserted at any scale and angle. Please note that you cannot insert empty documents as XRefs.

XRefs can be placed as normal or advanced XRefs. For more information, see Comparison between normal and advanced XRefs.

An XRef is always placed so that its size matches that of the elements in the document. If the size changes later, you can update the extents using Update All XRefs on the shortcut menu. XRefs can be clipped. However, this is only possible when you modify XRefs. You cannot clip them when you place them.

Using Show/Hide, you can switch XRefs and XRef borders on and off. Regardless of this setting, Area detection always takes into account the XRef border. To avoid this, you can place the XRef on a separate layer and hide this layer. In the case of advanced XRefs, the program still considers the elements in the XRef.

XRefs are always placed on the current layer. However, the individual elements of a XRef retain their layers. When you modify the status of a layer, you need to refresh the display so that the elements within XRefs are also updated.

You cannot create nested XRefs (in other words, documents including XRefs cannot be inserted as XRefs again). If a document, which has been inserted as an XRef, no longer exists, the border and the reference are retained and the file name of the associated document is displayed in the border.
