Hi!
Use online viewer
like this https://regard-house.ru/3dplan/vsn/3i.html

Since i cannot read this writing this online viewer is also unusable for me... [:-/]
And I'm not a the one who has hundreds of links for every eventuality... I like to have as much options as possible on one site. For this reason the online viewer on this site would be very cool.

But as I wrote before, it's only an issue for me. Perhaps I'm the only stupid one to create this damn big projects...

And if I have some time left, I can create my own online viewer on my webspace. So the size limit of the viewer here can remain for the given reasons.
