We searched a lot for getting real life cable trays which we can use in our modeling project. We were able to find some 2d dynamic blocks Cable tray, Revit families with some limited functionality. Also we tried to create cable tray in AutoCAD MEP, but we gave up after some time. Lastly we tried to do this by using AutoCAD 3d objects & then giving it dynamic properties. To our surprise we were able to do this & found that by doing some twicks we can add dynamic blocks properties to 3d objects too. We are very pleased to share this with Augi community.
