The -XREF command is used to attach a DWG file as an external reference.
Command Prompts:
Enter an option[?/Bind/Detach/Path/Unload/Reload/Overlay/Attach] <Attach>:
Specify insertion point or [Scale/X/Y/Z/Rotate/Pscale/PX/PY/PZ/PRotate]:
Relative Glossary:
?：
List the name, path and type of DWG reference, as well number of DWG references which attached in current drawing.
Bind:
Change specified DWG reference to be a block and make it become a permanet part of drawing.
Detach:
Detach one or more DWG references from drawing, deleting all instances of a specified xref and removing the xref definition from the definition table. Only the xrefs attached or overlaid directly to the current drawing can be detached; nested xrefs cannot be detached.
Path:
Display and edits the path name associated with a particular DWG reference.
Unload:
Unload selected DWG reference.
It may leave a mark at the position where the xref located for reloading.
Reload:
Reload one or more DWG references. This option reloads and displays the most recently saved version of that drawing.
Overlay:
Display the Enter Name of File to Overlay Dialog Box . Select the file you want to attach to a drawing as an external reference (xref) overlay. If you reference a drawing that contains an overlaid xref, the overlaid xref does not appear in the current drawing.
If the xref you specify is not already overlaid, a new xref is created, using the name of the referenced file. You are then prompted for an insertion point, scale, and rotation angle, as described for the INSERT Command. Inputting "~" to display the dialog box.
Attach:
Open the Dialog Box corresponding to the selected reference type.
Specify insertion point:
Specfiy the insertion point or options.
Scale:
Set the scale. In the xref, all X and Y dimension will multiple by X and Y scale factor. The inserted xref will rotate around the rotation center by rotation angle.
X,Y and Z:
Set the X,Y and Z factors.
X factor:
Define X,Y and Z scale factors.
Corner point:
Using a rectangle to define X and Y scales, and define the rectangle by specifying two corner points, and then define Z scale.
Rotate:
Insert a rotate angle for the xref.
Pscale:
Set scale factors for X, Y and Z scale factors to control the xref display when dragging in place.
PX, PY, PZ
Set the X, Y and Z axes to control the xref display when dragging in place.
Protate：
Set the rotation angle when dragging the xref in place.
