https://www.aras.com/community/f/development/3550/making-cad-documents-slave-to-partsHello All, I&#39;m in the midst of setting up our Innovator environment for doing PDM and PLM. We&#39;re currently on SP9 (soon to be SP12), and use Solidworks with the Softech Connector. I&#39;m trying to keep things fairly simple, and we&#39;re intending to use theen-USTelligent Community 12https://www.aras.com/community/thread/1254?ContentTypeID=1Wed, 24 Jan 2018 09:41:35 GMT916d3f7e-8ddc-42f8-8d45-380822f51406:f6979134-0bbb-47c9-8895-94f3f8665b5eChristopher GillisHello, While I haven&#39;t seen a customer implement this exact use case before, we have had customers use custom versioning logic previously. In those cases, we&#39;ve recommended creating two custom properties &quot;my_custom_rev&quot; and &quot;my_custom_generation&quot; to track your revisions that won&#39;t be affected by the built-in versioning logic of Aras Innovator. There are a number of different ways to achieve the result you&#39;re looking for, but one idea would be to take advantage of the standard Part CAD relationship and create an onAfterAdd/onAfterUpdate server event that makes sure that your custom version properties of your child CAD items always match those of the parent Part.
