I need help with an organic roof structure (see attached CAD plans and 3D views). It’s a cross-shaped structure with curved, organic boundaries and internal space trusses.
My Challenges:
Surface Logic: How to construct a smooth base surface for this irregular 4-wing shape?
Structural Mapping: I need to generate the spatial truss system (top/bottom chords and web members) that follows the curvature of the surface.
Variable Depth: How can I control the thickness/depth of the truss parametrically?
There isn’t anything attached - can you provide a OneDrive, Google Drive, Dropbox, Box, We Transfer, or similar link? Make sure it doesn’t require a log-in.

Please note that the annotations in the file are in Chinese. My main goal is to build a 3D model of an irregular steel roof. Specifically, I need to generate the “3D curved steel pipes” based on the 2D drawings/data provided in the file.
If you need me to translate any specific text, layers, or parameters in the file to help you understand it better, please let me know. I really appreciate your time and expertise!

Just to add a bit more context: The file I uploaded contains both 2D plan and elevation views. Could you please let me know if it’s possible to generate the 3D curved steel pipe model using just these 2D drawings? Thanks again!
Elevate the curves in cad and/or rhino 3d, you can then loft them.
At the moment your lines have no height and dynamo wont do that part for you.
See it as having to build the profiles your form has to pass through to produce the underlying surface.
From there you could project your framing curves onto that surface and divide/match them to curves projected further above or to the roof above to form your cavity frame.
Thank you all for your insightful advice! I have successfully completed the task. My workflow involved extracting curves from both the floor plans and elevations separately to generate the 3D spatial curves, which were then used to create the double-curved pipes. Due to the inherent limitations of Revit’s structural framing for complex geometry, the spatial double-curved pipes are composed of numerous small straight segments to approximate the curve. Here is the final model I’ve built, as shown in the image below.
