AutoCAD 2014 simplifies the display of linetypes and layers when using externally referenced drawings making it easier to find relevant linetypes.
Xref linetypes are no longer displayed in the linetype list of the ribbon or in the Properties palette. Here you can see the difference between viewing a linetype list for the same drawing in previous releases of AutoCAD compared to AutoCAD 2014.
Similarly, in previous releases of AutoCAD xref layers are displayed in the Properties palette even though you can’t do anything with them.
In AutoCAD 2014 Xref layers are still displayed in the ribbon so you can control their visibility. However, they are not displayed in the Properties palette making it easier to find layers in the currrent drawing.
In AutoCAD 2014 you can easily switch the attachment type for an xref between Attach and Overlay by double-clicking on the Type column in the External References palette. A new option in the right-click menu enables you to change the xref type for multiple selected xrefs at the same time.
In addition, the External References palette includes new tools to easily change the path of selected xrefs between Absolute and Relative. You can even remove the path completely. The –XREF command includes a new PATHTYPE option enabling you to automate these path changes through scripting.
