How do I merge meshes?

I have a collection of convex sealed meshes. Sixty-odd of them. How do I boolean-union all those meshes in one go?
How can I select all those meshes and have them merged into one solid mesh without duplicate faces inside?

Clicking through Boolean modifiers for each of those object works, but it is tedious. How do I automate it?


dont knowif it works with your meshes but you could enable the bool tool addon.
select all the meshes you have and press “strg” + “+” than “ALT”+“C” and > convert to mesh.

Honestly, the best way I have found to do this is to upload it to Shapeways, and then download it again. Their boolean union algorithm is top notch.
