Why does old nodes do not work in new build

[Joe.Charpentier]

Luchbox has not been maintained for Dynamo for a while. APIs have moved on since Revit 2017.

You will probably need to recreate this functionality using out of the box nodes or an alternate package.

Lunchbox alternative

Not that you are looking at the Panel nodes, but just for context we are releasing our own Panel nodes soon in Dynamo Here’s a sneak peak… [image] Edit: These are all native to our Geometry kernel and are pretty fast and responsive The nodes need a few more helpers as they are currently meshes and need to be promoted into Surfaces as needed.
