Object Placements / Georeferencing

camontellano

This is a long discussed topic. With the servers being moved and the things reorganized, my links are not working anymore. If someone could please put me back in the right direction, I'd appreciate it very much. I'm looking for:
1. Documentation on how to place objects in IFC (object placement, cartesian point, the location matrix)
2. Georeferencing done correctly
In the Wiki there were awsome explanations, written by @Moult 3. and I cannot find them anymore.
At least one of the first (but old) articles of @Moult in this regard is still there. So here my link:

Also as study material I remember someone had a kinda old but useful technical document about this matter, it was a pdf for the 2x3 version describing how object placement works.

I'd recommend this resource https://docs.blenderbim.org/users/georeferencing.html - does that answer all the questions?

Exactly! That is one of the ones I was looking for.
