I am trying to change the Graphics Override for layers in a linked DWG. I know that there is a Node form Bimorph to change the Visibility but not the color (@Thomas_Mahon):

> Hi, I am looking to hide/uncheck layers in a linked CAD file within a view like a Drafting View. There is documentation on how to change line colors, etc but I am having trouble pin pointing a way to simply hide a layer in a view via Dynamo/API. To shortcut initial steps I can use @Thomas_Mahon Bimorph Nodes to obtain all CAD Links and their Layer names. The Bimorph CAD.SetObjectStyle does not include an option for turning off a layer by name. Is there a way through the API or functionality in …

There is also a node to change the Object Style:

> Yes, just use List.Map: Also, I’ve found a hack to get Python to force the line colour update without you having to hide/unhide the reference: It’s pretty strightforward really; I’ve simply automated the hide/unhide step. #Copyright 2016.

There are even options to override an element, but I found nothing to override the Color for a View.

Could someone help me?

Thanks!

Maybe this?

> Hi Kulkul, Thanks unfortunately the problem is having several hundred layers which need their width to be set… Just for 1 view would be fine. Is it an API limitation do you think? Cheers, Mark Edit: If Revit would just recognise the object style setting, none of this would be a problem!
