By selecting the framing element, the tool should automatically identify the reference plane associated with it. do we have any node ?
hi @vikas.k.vk946.vk and welcome to the community… could you show what you have tried so far in dynamo, seems like a family, probably you cut with a refplane in project,right ? and not ref from family itself…if that the case you could maybe try with some intersect and maybe other ways as well but hard to say
Has the ref plane a name ?
