So I am familiar with Chief Architect and wood framing.
You model your wall based on a wall type selection and later tell CA to build the frame structure so the contractor and cut the lumbar and build the frame.
Easy.
Now how does this work with BIM?
For example I understand with BIM you can select walls like defining interior framing sheeting exterior finish etc.
How from that BIM selection of walls can you letter get precise guides how to build the house?
I am always wondering about brick work like exterior and how they make sure that you dont need cut bricks.
While I teach in interior design I am not an architect but such questions I find very interesting and I would like to know more about it
And how this would work in FreeCAD.

Re: Non-architect question about BIM process
bim is a workflow. e.g. a wall structure results from the geometry of the drawing and the lettering, regardless of bim. just like before bim
Re: Non-architect question about BIM process
I should have asked differently
So when you use BIM in freecad for a wall (interior)
Sony it have internal framing wood or steel and drywall finish
How would this from BIM translate into construction drawings ?

Re: Non-architect question about BIM process
most bim data are contained in ifc files. geometry similar to iges and text attributes to objects. These attributes can be individually expanded so that the companies involved in the construction can agree which attributes are required and how they are "formatted".
Re: Non-architect question about BIM process
BIM does not mean you do not have any drawings anymore. Your drawings might not be "painted" they are devated from the BIM model.
May be the data from the BIM-model is transvered to the manufactor directly, thus he does need to read the drawings and manually put all the wallues in his machine.
Lots of BIM workflows have been used for years in some building industry especially wood constructions.
Some BIM workflows are new ...
If you would like to build the house without any drawing you need to give the people on building site some other manual (eventually a drawing ia a manual to build a hous) to build the house.
BIM does not explicit define the processes. It just suggests to make a building model and use this for the building and manufactor process.

Re: Non-architect question about BIM process
As an architect you usually draw a wall as lines with fill hatches, which describe the type of used material for each wall layer (classical 2d-drawing, or derived 2d-drawing from 3d-model). With BIM it adds the data component to the wall, mostly in the form of machine readable object properties, e.g. wall layer is of type sheet metal studs or bricks of thickness xyz and material abc.
As an architect one usually does not draw the inner structure of walls. eg. single wood framing elements or rows of bricks. That is just too much detail. If needed, this is done in later stages of the construction process and mostly left to the construction company.
For Revit there is a wide range of plug-ins which do that for framing, see for example https://strucsoftsolutions.com/mwf-pro-wood/ and https://agacad.com/products/bim-solutio ... e/overview, or for preparation of precast concrete elements, see https://agacad.com/products/bim-solutio ... e/overview
These kind of details (no cut stones on brick blend walls) are a result of tightly communication between planning and construction. Don't hope to draw/model a building in every single detail, hand the plan to construction and expect it to be build exactly like on the drawing. There are a million ways which prevent that from happening, the most important is, there are humans involved.

This is usually done only in detail drawings. On the length of a whole wall you work with multiples of the length of the used brick and type of brick pattern and draw/model the wall accordingly. But you don't model each single brick of a wall. There are ways to display the correct pattern of bricks, see an example tutorial for Revit https://www.youtube.com/watch?v=A3ADR0Xrrmg, but this is mostly just a surface pattern on a wall, not a completely modelled wall with each single brick.
