The Service Pack brings back the Array dialog functionality by introducing a new ARRAYCLASSIC command. It also introduces the option to restore legacy Snap behavior by controlling it through the new SNAPGRIDLEGACY system variable:

Creates copies of objects in a regularly spaced rectangular or polar array.

1 – Always snap the cursor to the grid
0 – Only snap the cursor to the grid when AutoCAD prompts to specify a point

The following defects have been fixed:

3D Navigation Tools

  • 3DConnexion settings are not being remembered after changes are made.
  • 3Dconnexion device will not cancel the current command.

3D Surface Modeling

  • With dynamic input off dragging the height handle of an extruded line will not always stretch by the value and direction of the drag.
  • AutoCAD may become unstable when rebuilding a helix to a spline where the selection was not dropped.

Annotation Scaling

  • AutoCAD may become unstable while attempting to load a DCL file with errors from a long file name.
  • Tooltip does not appear when Additional tool tip string is set in “AcEdInputPointMonitor::monitorInput”.
  • API fix: This fix will respect the custom color, line pattern and line weight when selecting the entities including external reference.


  • Autoloader fails when SeriesMax parameter set to linked.
  • Autoloader loads partial CUI but may not display it when the bundle is removed and reinstalled.
  • When platform="AutoCAD*", bundles will be load on ACAD and Vertical.
  • Using Autoloader to add custom CUI files that contain WPF Custom Controls will not work as it needs a registry entry.


  • AutoCAD may become unstable while snapping to blocks containing OLE objects.
  • Editing attribute text in EATTEDIT dialog sometimes results in a fatal error.

  • You may receive an error at the command line after enabling a WinTab driver and the tablet will not function.

Display Drivers

  • Integrated chipsets are unable to return available video memory correctly.

  • AutoCAD may become unstable when using the "UNDO" command on drawings that are 2 gigabyte or larger.


  • Ordinate dimensions in paper space are not correctly reflecting the distance from paper space UCS.


  • AutoCAD may become unstable while closing a drawing after etransmitting it using the COM API.

  • The layer state Ribbon control does not honor the apply properties viewport overrides.


  • AutoCAD may become unstable when drawings with multileaders are saved to older versions.


  • AutoCAD may become unstable when editing polylines.
  • NCOPY may fail to copy objects contained in blocks that were inserted into paper space.


  • Mtext Paragraph spacing value cannot be edited once a value is set.
  • True Type (TTF) font text or mtext is blurry, bold, and distorted when the viewport is non-orthogonal because XY values are not exactly zero.

OLE (Object Linking & Embedding)

  • AutoCAD may become unstable when copying from an Excel file back to AutoCAD.


  • Cannot open drawing files from file Explorer if the drawing contains a "'%'" in the file name.


  • AutoCAD may stop responding when saving and or opening drawings with Symantec Norton 360 Version 5 installed on your system.
  • You will be unable to open drawings created using a non-Autodesk product when using the Open() API.
  • AutoCAD may become unstable when selecting the grid in some drawings.
  • AutoCAD may become unstable after editing MTEXT in a viewport and when exiting the program.

Parametric Drawing

  • Area is wrong when coincident constraints are applied to entities.

PDF Export

  • AutoCAD may become unstable when using PDF Export on files that contain MS Mincho font.

PDF Underlay

  • AutoCAD may become unstable when unloading a PDF underlay.
  • AutoCAD may become unstable when an undefined PDF underlay is unloaded.

  • With Snap enabled, the cursor does not move to snap intervals.
  • Turning SNAPGRIDLEGACY ON will restore the old Snap behavior of the cursor when no command is active.
  • Restores legacy SNAP behavior during certain LISP-based selection commands.

Sheet Set Manager
