i searched the forum and studied a lot of threads concerning the Parameter topics. I tried coding following tasked but i failed (Revit 2017, newest dynamo, clockwork package).:
A want to add a new Parameter group into a system Family for example into walls (like the ID Data Group) “Test Parameter Group” within 3 empty Parameters “Test 01”, “Test 02”, “Test 03”. I tried diverse examples which was posted here but i only get it done till a new Group was created without the new Parameters. The new created group also Wasnt shown at the wall Family. I tried also the example with the excellist Shared Parameters but this one crushed my dynamo (After press run nothing happened- seemed my machine was calculating but no warnings etc.).
How is this workflow possible? Thanks for some Input
