New Feature and Feature Enhancement Summary (2018.1 Update Section)

The following table summarizes the new features and enhancements provided in this Update. For detailed information, consult the AutoCAD 2018.1 Update Preview Guide.

Feature
New Feature or Feature Enhancement
Feature Comments
Xref Layer Property Enhancements New Feature To provide more flexibility for controlling xref overrides, the Layer Settings dialog box, which is accessed from the Layer Properties Manager, includes new controls for managing Xref layer properties. When the option to retain overrides to xref layer properties is turned on with the VISRETAIN system variable, you can now specify which xref layer properties that you want to reload. The various layer property options are stored in the registry as specified by the new VISRETAINMODE system variable. The Layer Properties Manager also includes a new status icon to indicate when a layer associated with an xref includes overrides.

 

Primary commands and system variables: LAYER, VISRETAIN, VISRETAINMODE, XREFOVERRIDE

 

Views and Viewports New Feature You can now easily create, retrieve, and place model views together with automatically sized and scaled layout viewports onto the current layout. When selected, layout viewport objects display two additional grips, one for moving the viewport, and the other for setting the display scale from a list of commonly used scales.

 

Primary commands and system variables: MVIEW, NEWVIEW

 

High resolution (4K) monitor support Feature Enhancement Support for high resolution monitors continues to be improved in the Update. More than 200 dialog boxes and other User Interface elements have been updated to ensure a quality viewing experience on high-resolution (4K) displays.

For the best results, use the Windows 10 operating system and a compatible video card.

 

3D Graphics Performance Feature Enhancement The 3D graphics performance for the Wireframe, Realistic, and Shaded visual styles continues to increase depending on the content of the DWG files tested. For example, the median value for the frames-per-second performance in the six large benchmark models used increased by 37% in the Update as compared to AutoCAD 2018.

 

Primary commands and system variables: 3DORBIT, ZOOM, PAN, VSCURRENT
