2018
* Functionality also included in the AutoCAD 2017.1 Update18
Technology and performance updates
AutoCAD 2018 continues to offer improvements in performance and technology.
DWGfileformat
The DWG format has been updated to provide improvements in the efficiency of open and
save operations, especially for drawings that contain many annotative objects and
viewports. Additionally, 3D solid and surface creation is now using the newest geometric
modeler which has improved security and stability.
Saveperformance
Save performance is improved in AutoCAD 2018. Objects that will experience the greatest
improvement include blocks with annotation scaling, Mtext with columns and other
newer formatting, as well as attributes and attribute definitions with multilines.
In addition, automatic save functionality is updated so that saves are most often
performed incrementally rather than performing full saves, which are slower.
Highresolution(4K)monitorsupport*
Support for high resolution monitors continues to be improved in AutoCAD 2018 to ensure
the best possible viewing experience even on 4K displays and higher. Commonly used
user interface elements, such as the Start tab, Command line, palettes, dialog boxes,
toolbars, ViewCube, pick box, and grips are appropriately scaled and displayed as per the
Windows setting.
REGEN3*(NotavailableinAutoCADLT)
The new REGEN3 command regenerates the views in a drawing to repair anomalies in the
display of 3D solids and surfaces. When a 3D display problem occurs, REGEN3 rebuilds all
3D graphics in the displayed views, including all 3D solid and surface tessellations.
2Ddisplayandperformance
An update to Graphics Performance enables you to turn off smooth line display while still
taking advantage of high quality geometry.
