What have you tried so far?

I would run a data extraction on the cad instead of utilizing a link or import. Faster and keeps the Revit file clean.

may be u can understand by looking at this picture .
instead of revit family i need to use link revit model node .

there is a folder in my pc which is having 10 Revit models. I need to place them as a link instance with rotation by using cad as a reference.

Hi,

It doesn’t seem that easy and straight forward.
Hopefully this approach can help a little bit.
You could play around with these 3 nodes.

Steps:

  1. Link the CAD instance
  2. Read out the layer curves
  3. Get the center point
    (It would be better to run the data extraction on the CAD as Jacob mentioned, but then you would need to adjust the points to your coordinate system)
  4. Link the Revit file
  5. Set its location

Hope it helps a bit :slight_smile:

I understand the need; did you review the link I sent? It shows the later half of your problem, positioning a link instance. There is a node in GeniusLoci for this as well if you want to avoid having to own/maintain/edit Python on your own.

The Orchid nodes certainly resolve both halves of the equation, but that package can be difficult to get onto systems so avoiding it may be a good thing.

Creating the link type is likely the missing part of the equation. If I can manage to free up some time before the Dynamo Office Hour I’m co hosting tonight I’ll post something here for that as well; perhaps even incorporating the coordinate system as desired.

This graph should achieve what you want in Revit 2024; for older builds some Python code may have to be edited.
