Hi, I have been busy for a while trying to create a geometric surface, the Gyroid, but after several attempts, I have not had great success, I was able to create the model with Blender and successfully import it into Moi3D with import via SubD, but I don't find a method to do this directly with Moi3D, I attach my attempt obviously too sharp surfaces and I hope that others users can find a valid solution to this technical challenge.



The Gyroid.3dm File is a recent attempt with tangent curves, but it's not great, while the other Gyroid-blend-subD.3dm also contains the subdivision surface made with Blender with a smooth transition between the various curvatures. and the green one is made directly with Moi3D but the subdivision between the various surface pieces is too sharp even if it still seems to me an excellent result that I have not been able to improve.


This one has also the sub-D surfaces the orange one (attached as Gyroid-blend-subD.3dm)


This is a recent try as the gyroid.3dm file


And here the solid created with Blender and 64 patches



I also attach a video where with NX and CATIA this is possible
