for those who might be interested I recorded two videos on georeferencing in Bonsai
a few steps are missing (like export to DXF and extract coordinates and angle in QGIS) to make it short but I can add more info if necessary.
@steverugi
thx for the vids, to make it a little bit easier for noobs like me, can you attatch some keywords and links to the websites, qgis addons, if i didn´t add it correct or if there are some missing.
software: qgis, addon: "quick map services",
link uni delft geref: "https://ifcgref.bk.tudelft.nl/templates/guid.html"

thx, very much!
@Mas
you are welcome and thanks for mentioning the links
the purpose of the two videos was more to show the use of georeferencing data in Bonsai to link projects together and model them separately by using their 0,0 world origin and rotation, so that their own grid lines are easier to work with in local coordinates.
The same works with any offset plan by the way, the geographical coordinates are a plus to let models have their real-world locations, good for presentations etc..
Nice going @steverugi ! What i usually do to determine the georeferencing part with is use plain CAD and local vector data (maps). I my opinion Engineering can't be done without 2D CAD, CAD its just like a 2D calculator. There is opensource LibreCAD, in theory this can be used. Maybe you can check out one of my video's on ifcref and bonsai.
Same principals apply, ..
different routes to get there..

sure, what matters is to get to the result we need, I find Bonsai quite straightforward to geo-reference models.
QGIS uses projected coordinates converting them on-the-fly if needed, and has so many options for vector or raster mapping.
as 2D software I use QCAD (especially its Pro affordable version), it does a decent job, and accepts projections as well.
Some commands in QCAD work in QGIS' QAD plugin, in my opinion useful for quick sketching in QCAD map.
Happy GIS/BIM modeling !

It's in dutch but with subtitles.

Map conversation with the right world coordinates, links, north, maybe different units,... 💪🏻 🤌🧠
