Closing complex polysurface

Hi! I have this polysurface that I builded using all manner of wrong and hacky solutions. Of course, it has naked edges galore everywhere.
I just need to calculate it’s volume, I don’t need it to be very exact, whats an easy way to get a polysurface that I can calculate the volume on?

Hello - if you CreateSolid from the top and bottom surfaces (untrimmed) then BooleanDifference the inner part you’ll get something close




Thank you Pascal! I didn’t know about CreateSolid! I’ve been using Rhino for more than 20 years and still keep finding hidden gems :smiley:
