Hi Michael,

this are good news!

@Pilou
In the simple file is it no problem to find and delete the patches.
What I need is a waterproof solid to mill the model. The head is allready milled.
Searching for the double patches with mouse over or clicking, is no solution for me :D
Detaching all patches and delete the double and bool the result?

In my case I have rebuild the poly-model (a bit more density with the same polyflow) and re imported it to moi. Now it works and it's a solid. :)

Many thanks!

Here is an result
