How to extrude a section along two curves

avungyerd — Mon, 09 Sep 2024 08:25:38 GMT

Is it possible for Archicad to model a cross-sectional profile that follows a curve with two different curvatures, as shown in the image?

If so, please let me know how to do it.

Operating system used: Windows 5030

There is no easy way of doing that in Archicad. There is nothing comparable to the " Sweep2" command of Rhino.

With beams you can try the tapered method, but that does only work with straight segments.

However if you are proficient in GDL you could try to give it a shot. It still won't be easy tho, my best guess would be to make tiny segments with RuledSegmented where you'd need to calculate the profile node positions by hand, or maybe you can even get away with using TubeA, depending on your profile.

But none of this is trivial. I suggest to just use Rhino and bring in the Nurbs to Archicad. That works generally quite well.

ArchiCAD does not like splines...

Thanks for your reply, I decided to import the modeling in Rhinoceros.
