Trouble making watertight object

Rhino Rhino for Windows

Hi, I’m currently designing a boat in my spare time to try and run orca3D’s CFD analysis on.

unfortunately I keep getting an error message that says “selected object is not a watertight solid”
I have tried joining all the edges but that didn’t work.

thank you for your time!

Run the “Show edges” command and you will notice that the upper vertical surfaces at the rear deck must be extracted, deleted and replaced with new ones.

When you run ShowEdges turn on the the Naked edges option. Naked edges are unjoined edges.

ShowEdges should be the first command to use when you get a message about naked edges or an object not being watertight.
