The section line symbol within AutoCAD Mechanical is updated to support the AWS Y14.3 - 2012 standard revision. To support AWS Y14.3 – 2012, all aspects of the section line symbol are revised to correspond with AWS Y14.3 - 2012.

AutoCAD Mechanical continues to support the AWS Y14.3 - 2003 standard revision to allow documents created in previous releases to be opened, edited, and saved without updating the section line symbol standard. By supporting AWS Y14.3 – 2012 and AWS Y14.3 - 2003, you can annotate new and as-built designs using the required standard revision.

Activity Insights provides an understanding of the past actions that you or others have performed with regard to your drawings.

Activity Insights tracks events whenever a drawing file is opened and being worked on in AutoCAD. It can also track some events outside AutoCAD such as a drawing rename or copy in Windows Explorer. When a drawing is opened, past events performed in the drawing are read from the Activity Insights database and displayed chronologically in the Activity Insights palette. At the same time, events are being written to the database as you work in the drawing, which keeps the contents of the palette current.

Changes are written to the Activity Insights Event Location specified in the Files tab of the Options dialog box. The default location for the Activity Insights Event Location is C:\Users\{username}\AppData\Local\Autodesk\ActivityInsights\Common. Change this to a shared location so that any drawing activity is logged in one location regardless of who works on it.
