The ADF elements available for creating diagrams in diagrams.net
Use this link to open a blank diagram in the online version of diagrams.net that has the four different ACES ADF palettes ("libraries") available.
Download the xml files in libraries/ and load them as libraries in diagrams.net/draw.io via File -> Open library.
In source/, there is a .drawio-file with all the elements that are used to generate the libraries. See Wiki of this project for more information on how to edit the file and libraries.
