QUESTION
How do you replace imported "proxy" objects with trees or lights?

ANSWER
The Place item on nodes function (Node Replacement) allows you to replace multiple imported "proxy" objects with trees/plants or lights of your choice.

The function works with Revit, SketchUp, ArchiCAD, AutoCAD, AllPlan, 3DS Max and Rhino (see the steps and export requirements below).

Each "proxy" object has to be a separate object with its own position/rotation/scale, for example some duplicated boxes (or columns in Revit).

Important: Make sure you assign a single material to all faces of the objects.

When replacing imported "proxy" objects with Spotlights, please note that the "proxy" objects have to be rotated by 90 degrees in your CAD package to look correct after replacement in Lumion.

It is available via the Context Menu for imported models:

Context Menu -> Extra -> Place item on nodes


GUIDELINES:
  • Revit: Install the 'Lumion LiveSync for Revit' plug-in if you're using Revit 2015-19. Tick the 'Export nodes' button in the 'Export as Collada file' settings before exporting a .DAE file to Lumion. Please note that when you use the 'Place item on node' function in Lumion after importing a .DAE file, it will place additional objects at the insertion point of the .DAE model. Simply delete those objects.
  • SketchUp: Export the proxy objects to .DAE format and make sure that 'Preserve Component Hierarchies' is turned on.
  • ArchiCAD: Export the proxy objects to .3DS format with the default export settings.
  • AutoCAD Architecture: Make sure that your proxy objects are 'Mass Elements', not '3D Solids', and then save the "proxy" objects to .DWG format. Install 'DWG To Lumion Bridge', start Lumion and import the .DWG file.
  • AllPlan: Export AllPlan proxy objects to .SKP (SketchUp) format. Then open SketchUp and export the model to .DAE format. Make sure that 'Preserve Component Hierarchies' is turned on in the .DAE options.
  • 3DS Max: Export the "proxy" objects to .3DS format with the default export settings.
  • Rhino: For those using Rhino, there is an interim solution in this forum post. Please note that license registration is required to view it.

STEPS (USING SKETCHUP EXAMPLE):
1) Create a box for use as a "proxy" object and right-click on it -> Make component or Make Group.  Assign only a single material to all faces of the object.  Duplicate the box as many times as you want. Then export the scene as a .DAE file.


   



2) Import the file in Lumion and place the "proxy" objects in the desired location (See this Knowledge Base article if you need to align the "proxy" objects with an existing model).




3) Select a tree/plant or light in the Model Library that you want to place at the same location as the imported "proxy" objects.




4) Select the Imported Model category again and click on the Object Icon of the imported "proxy" model from 3DS Max/Revit/SketchUp -> Context Menu -> Extra -> Place item on nodes.

If you have the SKP file open, then a Windows Open File window will now pop up. Select the SKP file you saved earlier, and click on the Open button.  Otherwise, the nodes will now be used to position the Tree or Light you selected.




5) Remove the original imported "proxy" model to see the finished result:





See Our Video Tutorial:  Build Mode: Node Replacement For Trees:  Replace 'nodes' with the current selected tree by using the context menu.
