Model contain overlapping surfaces

I received the following warning when I do

top4 add Volume 28 Volume 32 Volume 24 Volume 20 
volume 28 32 24 20  size auto factor 8

However when I run find overlap surface all, there’s no overlapping surface pairs. How shall I address it?

Besides I did imprint and merge before meshing operations.

i can mesh your geometry with

reset vol all
Volume 4 8 16 12 scheme polyhedron
mesh volume 4, 8, 12, 16
mesh vol all

What do the power tools show you when you run a check?

Well I can mesh it if I mesh the volumes 1 by 1. But if I choose several volumes together, the error occurs.
I
reset vol all solved the problem. Thank you :slight_smile:
