Grasshopper Solid Union Error

Hi Everyone,

I have created some surfaces in rhino and bought them across into grasshopper and capped all the surfaces into solids. However, when I try to merge the solid objects into one I get this error sign?

To create the surfaces I have used the loft tool in rhino. Some of these overlap to create tree branches. When you scale one of the branches down they seem to merge perfectly. I have too many trees to manually go around and scale every branch down. Is there an alternative way to resolve this?

Thank you!

Maybe “JoinBreps” on the uncapped surfaces will work better.

Can you upload a file with a part of your geometry?

What is your goal, visualization, fabrication? Does it have to be breps or could it be meshes instead?

Hi Lando,

Thank you for your reply, i ended up manually doing all the trees on the site. I did try and complete this as messes and still failed. But thank you for the suggestion.
