I am modifying a 3D scanned model , I want to join the upper and lower parts of the shoe.

I didn't know how to do it in sculpt mode, so I did a merged the vertex in edit mode, but it didn't work. (Please refer to the image)

Also, I found an article asking the same question. https://blenderartists.org/t/how-to-fill-the-holes-and-avoid-overlaps-in-sculpt-mode/641648

Is this impossible even as of 2021 without using add-ons?

I'm new to 3D scanning and sculpting, and I'm sorry if it's a rudimentary question.

  • $\begingroup$ Why even using sculpt mode to fill holes in a mesh object? It's not meant for that. There are automatic tools (mesh clean-up > fill holes) which don't always do a good job, there are manual tools (selecting vertices and moving / snapping them), there are different programs like Meshlab which have more serious toolset for that $\endgroup$

  • $\begingroup$ Thanks for a reply! I tried to use fill hole tool, but it did not work. And about snapping tool : I couldn't come up with the idea! I will try it! Also thank you for telling me about the existence of Meshlab. $\endgroup$

The way I do it is joining the necessary parts and then remeshing it using voxel remesh option. The model will become one piece. So if you have large holes or things that are separated - just join them Ctrl+J and remesh.
