Hi,
Can I find an easy and good way to model these parametric curved furniture pieces like these images, knowing that and of course to be ready for manufacturing with laser or CNC cutter?
I’m using Revit and am new to Dynamo, and I also use Fusion 360 for modeling
Thanks much
I’m guessing yes, but you didn’t post any image for us to review. Links are fine if you can’t post everything as a new user.
Yes, entirely doable.
Build the solid for the complete shape, pull the surfaces and create a polysurface. Next build a series of planes that match the CNC plands you want. Intersect the planes with the polysurface, and you’ll get a series of curves. Union each of those into a polycurve, find the minimum bounding box for each (BoundingBox.ByMinimumVolume), pull the coordinate system and width of each bounding box, and transform the polycurves by the coordinate systems, and translate the transformed polycurves by the sequential width values.
Thank you very much for this comprehensive and detailed answer to the topic, and I would be very grateful if you send me a video or a series of tutorials that explain the process so that I can make this model.
Excuse me, I am still new to working on the Dynamo program, but I have good experience in the Revit.
The best next step here is for you to begin learning Dynamo if you are a beginner I think. Look into the Dynamo Primer which should introduce you to creating solid forms for cutting. We don’t generally produce tutorial series here on demand, but rather guide and troubleshoot where people get stuck.
Maybe try making the form in Revit using conceptual massing, then using the element.solids node to get your base form to begin with if you’re unsure how to build the full form in Dyanmo. Each of those reference images would be a very different algorithm to make the underlying surfaces, and you’d probably need to learn about sin/cosine wave forms to make some of those guidance curves in Dynamo.
My preference is generally to ultimately place adaptive components for better native control, but you can also generate direct shapes using various nodes in custom packages or in later builds ootb.
I’ve attached an example of using a cumulative attractor to add a 3 point form of this nature, but it’s just an example - your algorithms will differ. Personally for these types of forms I typically use Grasshopper for better native control (you can natively make lofts out of curves more easily, and use the graph mapper components for more fluid control), but hopefully this helps if your preference is Dynamo.
I strongly encourage you to invest some good time into this, many will come back immediately with more questions and no worked examples in these types of scenarios but exploring the platform a bit will always be better for your learning journey. I will take time (none of us picked of Dynamo overnight), but stick at it.

This is an example of what I drafted up in Grasshopper based on 3 guidance curves only and a simple script. Do consider it as an alternative if it seems more beneficial to this task. Rhino Inside Revit is a very viable approach also in my experience. You could achieve a very similar outcome in Revit for the freehand curves in the conceptual massing environment, although I find drawing splines a bit less rigid in Rhino vs Revit conceptual.
Many thanks for this perfect answer, I’ll learn more about Dynamo and get back to making some abstract models like these.
Best regards
Do check the share category, lots of good stuff there, (just a tip.)

Hi, Marcel
You can join us to learn more about design scripting and design all these models with dynamo.
If you have any sources of data that can help us please share.
One thing to note: if you already know Fusion, there are some pretty great things you can do with that as a base; no need to move to Revit or Rhino + Grasshopper.
@Lynn_Kim does some AMAZING work on her youtube channel (in Korean but you can usually follow along all the same, posting any questions in the channel or here). This is the “Dynamo” portion of the channel which makes for an an amazing watch if you’re looking for learning, understanding of the capabilities, and inspiration: https://www.youtube.com/playlist?list=PL2zQm_9Jg97z7GUXSgtvgrfIpYdzGWvLQ
Many Many thanks Jacob for this channel, she has awesome videos that show exceptional models.
I’ll watch all of those videos.
