"""""""""""The last 2 have a kind of alien wart effect.""""""""""

Save the code project at those steps.. Later, they could be a plug-in addition!!!!!

"Alien Wart skin" maker. :o

Indeed curious! :)
biz2, biz3 ok
but on my old computer (10 years old)
here the biz1: in not a speed time of loading 70 ko = 5 minutes
the biz0: 1.5 Mega I abort after the loading not a reasonable time!

Hi Pilou, do you have a tighter than default angle set for Options > View > Meshing parameters?

The default for that value is 10 degrees, which already generates pretty dense display meshes. If you have it set to an angle less than that, it will cause really very dense display meshes to be created which will consume a lot of memory especially on chaotic surfaces like these.

Especially if you have an old computer you probably will not want to set it to less than 10 degrees.

Yep that was that!

Now I put 50 and it's instantaneous even for the 1.5 mega file!
Cool !:) here Biz

very interesting, thanks for sharing, and not only Architects, but object designers too

With this code you can start a new version of Moi for Post-modernists. They'll jump all over it :)
