The selected object is not a manifold solid

I use Slicer5. But I got massage “Select object is not manifold solid”, I tried to find the lost face or something wrong but I found nothing,

You could try Solid Inspector² to find out why your model isn’t solid.
It’s a very useful extension.

It’s well worth learning the basics.
A simple delete and you have a solid.

When I get into these situations and I know the face is the correct shape:

edit the group,
select the face,
copy the face,
select all,
delete,
paste in place,
push pull the face to the proper distance

Don’t make multiple posts on the same topic. One is enough. I responded to your previous post.
