How to Create a Christmas Reindeer With Autodesk Dynamo

I was in our office last week when our marketing team asked me to help them create an Excitech Christmas image to send to our customers using Revit.

After quite a bit of thought, I knew that Autodesk Dynamo would need to be involved to create something a bit more interesting than a gift-wrapped box with a red bow on top!

I hadrecently been looking at the Mesh Toolkit for Dynamo and after a bit of searching, I found a low poly model of a reindeer and tested this with the Mesh Toolkit. Here is how the reindeer appeared when imported into Autodesk Dynamo:  


The next stage was to add a little context and scale to the reindeer. The group below rotates and scales the mesh, and then turns the mesh edges into lines. This then leaves the 3D wireframe representation of the mesh model. 


The wireframe model is then passed into the group shown below to create a structural framing and to ensure the frames are set to centre. I created a custom CHS section with three materials that can have illumination set within the material. 


The second part of the script requires the randomisationof the materials that are applied to each structural section. The first two nodes collect all the structural framing members from the project and then the items are counted. Meanwhile, two materials are called by name and then cycled to generate the correct quantity. The list is then shuffled to randomise the order, and each structural member is then assigned the random material.




Finally, I created a topographic surface for the snow and added some RPC trees from the Revit library. Extra points were added to the surface to represent the appearance ofreindeer's footprints. 


The scenes were then rendered in the cloud using the Autodesk A360 rendering.



And there you have it, Excitech’s Christmas Reindeer created in Autodesk Dynamo. See it in action here: https://www.youtube.com/watch?v=Y97GyTmn54o
