I am trying to copy all writable Instance Parameters from one Family to another inside a project (RVT). I have found the following thread but the Graph images aren’t readable: [Copy Instance Parameters Between Two Families](https://forum.dynamobim.com/t/copy-all-parameter-values-from-one-family-instance-to-another/1391)
