How to close Open Breps?

[michaldengusiak]

I have few spaces baked as breps

unfortunately, only two are closed

I visualised in Rhino naked edges and tried to merged edges… seems to work but still, one point is left

when I load this into grasshopper it shows me that is still open polysurface

I tried standard solution but did not work

Q1. how can I fix this in rhino to remove this point… would that make it closed?

Q2. Is there an alternative way to close my breps in GH?
I guess this is a complex subject but maybe there is sth I missed…

Hi Michal!

I don’t know why this happens. but usually when you explode and re- join the polysurface in rhino make closed polysurface. for grasshopper I don’t have any idea except using python rhino library to do the same procedure.

If you consider this case as a kind of tolerance issue…

It closed 8 out of 12 by exploding and joining, not bad…

thanks it worked on all of them I just think if rounding to two decimals will not mess up whole building…
I am struggling to graft this tree correctly as I need each space as separate item ()closed brep in tree. Could you help with this.
