Hallo,
Ik ben nog niet zo lang bezig met autoCAD en ik vroeg me af wat xref nu precies doet en waar het voor dient. Weet iemand dit ?
Bedankt
Hey,
Al eens F1 geprobeerd...???
CiteerControls external references to drawing files
Attach External References
When you attach a drawing as an xref, you link that referenced drawing to the current drawing; any changes to the referenced drawing are displayed in the current drawing when it is opened.
The program treats an xref as a type of block definition with some important differences. When you insert a drawing as a block reference, it is stored in the drawing and is not updated if the original drawing changes. When you attach a drawing as an xref, you link that referenced drawing to the current drawing; any changes to the referenced drawing are displayed in the current drawing when it is opened.
A drawing can be attached as an xref to multiple drawings at the same time. Conversely, multiple drawings can be attached as external references to a single drawing.
The saved path used to locate the xref can be an absolute (fully specified) path, a relative (partially specified) path, or no path.
If an xref contains any variable block attributes, The program ignores them.
Note Xrefs must be model space objects. They can be attached at any scale, location, and rotation.
Notification of Attached Xrefs
An xref icon is displayed in the lower-right corner of the application window (the status bar tray) when xrefs are attached to the drawing.
When one or more xrefs are not found or if any of the xrefs need reloading, an exclamation point is added to the Xref icon. If you click the Xref icon, the Xref Manager is displayed.
Tools for Attaching Xrefs
To attach an xref, use XREF to display the Xref Manager or use XATTACH.
You can also use DesignCenterâ,,¢ to attach xrefs to a drawing. Use DesignCenter for simple attachments, previewing external references and their descriptions, and quick placement by dragging.
You can attach an xref by dragging it from DesignCenter or by clicking Attach as Xref on the shortcut menu.
Visibility, Color, and Linetype
You can control the visibility, color, linetype, and other properties of an xref's layers and make these changes temporary or permanent. If the VISRETAIN system variable is set to 0, these changes apply only to the current drawing session. They are discarded when you end the drawing session, or when you reload or detach the xref.
Xref Clipping Boundaries
Drawings can include xrefs that are clipped. If you want to see the clipping boundary, you can turn on the XCLIPFRAME system variable.
Attachments from Educational Products
If you open, insert, or attach an xref from an Autodesk Educational Product, the drawings you plot contain the following banner: “PRODUCED BY AN AUTODESK EDUCATIONAL PRODUCT.â€

Een Xref is een tekening die je als het ware onder je huidige tekenig hangt.
Deze Xref is dus een file die kunt laden en ontladen.
Je gebruikt dit vaak als bv ondergrond als je een topografiesche tekening wilt maken.
Je kunt ook foto's op dezelfde manier gebruiken!
Ik heb veel geleerd in ACad door in de help te lezen en gewoon uit te proberen.
