The ISO standard now supports the latest revision of ISO 13715:2017 (E) for the Edge symbol.
The Edge Symbol ISO dialog box provides the most up-to-date notation and requirements. The dialog box supports various options and positions to place the edge symbol in the drawing. It also offers options to define the edge quantity and indicate the limited areas of the edge.
Note: The AutoCAD Mechanical toolset continues to support all legacy revisions. Documents created in previous releases can be opened, edited, and saved without updating to the latest standard. When saving the Edge symbol in the new revision to an older file format, the software converts the Edge symbol to a block.
