Hello ,
i jus created a building model and it is a polysurface … not i need to panel the facade of the building for which it should be a single surface. i tried various methods of regenerating the polysurface into a surface but failed. so can anyone tell me how to deal with it?
Hi Vineet- there is a much bigger chance that it is not possible than possible, but it is impossible to even begin to guess without a Rhino file.

where can i send you the rhino file?
Hi Vineet- no, the object you sent cannot be one surface.

okhay. so i have to panel each surface separately?
hi, you can use grasshopper to basically merge the data for those polysurfaces. that is normally what I do if I have to panel out a polysurface. set parameter as brep or u can explode your poly into surfaces. and then extract whatever attributes u want for those surface.
once you have extracted the attributes you can combine the data just easy with Merge component. as it is now under a single list, you can assume now it is a single entity in which u can apply any operation (offset, etc etc)
the good thing is that you can change your poly surface in rhino and see your panel updates in real time.
hope that helps

I have done a fair amount of reverse engineering work. And basically have plenty of experience doing similar work composing and networking surfaces together.
Pascal is most likely correct, that the geometry can’t be one surface, because it’s very difficult to get a single surface to conform to every curvature deviation. However, I’m super curious to see an image of your polysurfaces, because this type of problem is one of my favorites to solve. Though, the process can become very time consuming, depending on the circumstances.
Usually, it leads to a compromise of surface curvature deviation of some kind. But I’ve achieved some astounding surface networking techniques that can combine some high curvature deviations. While, your geometry may not be capable of being generated with only one single surface, it may be capable of being reduced dramatically in number.
… this being said of course without seeing what your geometry actually looks like…

Hi Vineet Are you using Panelling Tools? If so, you can use the one / two direction curve projection tool to panel a polysurface.
Sach
Thanks!
Seems to help me with SubD in Grasshopper!
@Runnie Hi, could you provide an example please? I’m not able to recreate this. Thanks
