Feature Limitations and Notes

Iso Reference Dimensions

Existing Iso styles and symbols need to be updated before creating isometric drawings that include isometric reference dimensions in an existing project.
To update the existing symbols and Iso style, create a new (empty) project and copy IsoSkeyAcadBlockMap.xmlIsoSymbolStyles.dwg, and IsoConfig.xml overwriting files in the existing Isometric and Iso style folders.

If a drawing containing Iso reference dimensions is opened in AutoCAD Plant 3D 2016 (prior to Extension), interacting with the Iso reference dimension may cause the program to shut down unexpectedly.
