I want to close this cross vault in order to have a volume cross vault.gh (25.2 KB) [image]

You want to close it all the way down to the groundplane? Or just the bottom of the arcs? close it with vertical surfaces?

I want to close it to the groundplane with vertical surfaces ( like in the simple vault below) [image]

thank you, but i didn’t mention it. The volume is until the groundplane :slight_smile:

Look at your screenshot, You are missing information into the flip curve (yellow means warning)

yes that’s the point I couldn’t make the cross vault in the same way of a simple one… @Michael_Pryor

Use @HS_Kim solution, it is simpler for you. I do suggest you give this a read though, so you can understand some stuff. https://issuu.com/pabloherrera/docs/mode_lab_grasshopper_primer_third_e
