Boolean not returning valid part

naregjan

I have a boat that I'm trying to model based off of four lofted sketches. I've been trying to hollow it out; I tried using both shell and thickness to do so. In either case, whenever I try to take the top of the boat off using any sort of boolean operation, I get an error. In this most recent iteration, I've got a 10mm thick shell, and when I try to get the intersection with a block I've extruded underneath it, I get an error. Here's the link. 

Why? How should I make it differently?

(also I realize this should probably be in "using Onshape," but I don't think I can move an already existent post)

Now posted here in a more appropriate venue, sorry 😅

@naregjan - Hello. In your screen shot Extrude1 is shown to be failing, but in the model it is succeeding!
In fact, the entire Feature Tree has no errors! (well done)

He ended up fixing it in the thread he linked to.

And herein lies the lesson of linking forum request posts to a revision of the doc not the live main workspace...
