What's New in AutoCAD 2018
Views and Viewports
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
3D Graphics Performance
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 AutoCAD 2018 Update as compared to AutoCAD 2018.
Primary commands and system variables: 3DORBIT, ZOOM, PAN, VSCURRENT
High resolution (4K) monitor support
Support for high resolution monitors continues to be improved in the AutoCAD 2018.1 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. Examples include the Edit Layer State and Insert Table dialog boxes as well as the Visual LISP editor.
Xref Layer Property Enhancements
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
Have You Tried...
The Help home page now includes a new heading called Have You Tried. If you click the link under it, you'll see that the topic is organized into two sections:
- The first section provides an introduction to a useful product feature that you might not have tried yet. Included are short exercises that will get you started quickly with things you can use for immediate productivity.
- The second section, Updated Help Topics, lists the Help topics that we've recently updated or revised directly in response to your comments in Help and on the AutoCAD discussion forum.
PDF files generated from AutoCAD drawings that contain SHX text store the text as geometric objects. You can use the PDFSHXTEXT command to convert the SHX geometry back into text, which now includes an option to use the best matching SHX font. The TXT2MTXT command has been enhanced with several improvements including the option to force uniform line spacing.
Primary commands: PDFIMPORT, PDFSHXTEXT, TXT2MTXT
The improvements include the following:
- Hatch display and performance are enhanced.
- Anti-aliasing and high quality graphics settings for supported graphics cards can now be controlled independently from each other.
- Off-screen object selection works as expected in all cases.
- The orange rubber-band line that appears when you create and edit objects can now be set to any color from the Options dialog box, Display tab, Colors button.
Primary system variables: LINESMOOTHING, HQGEOM, SELECTIONOFFSCREEN, OPTIONS
External Reference Paths
The default path type for external references is now set to Relative. Two new path options are available: Select New Path, and Find and Replace. Additional capabilities include the following:
- When you fix the path for a missing external reference, you can now apply the same path for other missing reference files.
- When you save the host drawing in a new location, you are prompted to update the relative paths for the external references.
- The Change Path Type option in the External References palette now reflects the current path type when a single external reference is selected. The current path type is not accessible, which lets you know which path type is current.
- You can attach references with Relative Path type for unnamed files.
Primary command and system variable: EXTERNALREFERENCES, REFPATHTYPE
3D Graphics Performance
Additional performance improvements have been made when using 3DORBIT, and panning and zooming with the following 3D visual styles: Wireframe, Realistic, and Shaded. For best results, we recommend that you use a 64-bit machine and a compatible graphics card.
Primary commands: 3DORBIT, ZOOM, PAN, VSCURRENT
DWG Format Update
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 now uses the newest geometric modeler (ASM), which provides improved security and stability.
Primary commands: OPEN, QSAVE, SAVEAS
