here is a proposal for a bim workflow.
first created e.g. the surveying office a master ifc file for the same origin and orientation of all following ifc files.
the architect creates a 3d sketch for the structural engineer as an ifc with reference to the master ifc.
Suggestions for improvement are welcome
Greetings Thomas
in this video you will see how the architect creates a modell from the static information, which he sends to the electrician as an ifc. the electrician creates an ifc file with the cables, sockets, etc.
then the two ifc files (from the architect and from the electrician) are merged into an ifc-bim model. for approval meetings, collision checks, etc

here is the ifc bim model for download

because it is very complicated to work together on a bim with many frequently changing companies with attributes, i suggest working with colors. that is very compatible and intuitive
here the difference between 220v blue and 380v red

here is an example of heating planning in the bim process. if you have skilfully saved the heating models (at the right height, standing and in the middle above the origin) you can quickly place the heating “hanging on the mouse” with move.

for tendering and billing, e.g. door lists are required.
in the bim process, however, you don’t want separate files that could be mixed up or contain old information. everything should be contained in the ifc file.
instead of working with ifc attributes, which are often incompatible, one could write the required information in the part names.
here’s an example

here is an example of using freecad to calculate volumes and areas and then creating an ifc file with the results (without attributes in the part names)

4D BIM
here is an example of room designations and room information (you can add more to the part name). very compatible. should work 100%
paper plans are often required. e.g. for a building application or the construction site. here is a way to print 2d and 3d plans with labeling and dimensions from the ifc model

and as a special case, editing an ifc file is possible

place parts “hanging at the mouse”.
here is a workflow to use ifc files from suppliers with attributes, texts, etc.
Any attributes are also possible that may be required by involved companies. this makes it possible to work on bim projects with 100% free software

high-performance bim model by simplifying the geometry
here is an example of a difficult ifc file,
https://grabcad.com/library/convenience-store-1
even commercial programs have problems displaying all geometries (here the reinforcement steel). ifcplusplus
https://github.com/ifcquery/ifcplusplus/releases/tag/1.1
opens the file very quickly and can display it. ifcconvert can quickly convert it to obj and freecad can edit it in detail with high performance.
https://www.youtube.com/watch?v=XSUmlo8vZZk
in the conversion phase to bim/ifc it can happen that 3d dwg files have to be processed. this can be done using the same quick and easy method as using difficult or large ifc files via mesh, here via sketchup
https://grabcad.com/library/house-4x15m-1
https://www.youtube.com/watch?v=HR3zFJM2jt4
Split large ifc files and use them as a mesh quickly and easily in the bim process

fast, stable work with ifc files including part names through part simple copy
