Wrap BrxBim classes

[CEXT-Dan]

@CEXT-Dan hope you're well. Could use functionality to import 1) IFC, 2) classify entities (for example by layer name) and 3) export to IFC. I believe it's all BCAD verticals. I am aware that there may be other priorities. Whenever you find the time I would be grateful to be able to script anything.

Have in mind that you're about to travel for longer. Wish you safe journey.

In progress, est two-three weeks

Saw that you're back online. Hope you're well. Please signal whenever I becomes reasonable to attempt scripting BRX24.2.03.0\samples\brxBimSample\BimIfcImport.cpp

[CEXT-Dan]

I’m going to defer this until V25 is released, reason is, there appears API changes between beta versions. I find myself having to redo stuff.

Hi, do you have any sample data I can use to test? I'll try to push hard on this next week. Admittedly, this wrap is hard for me, I've never worked with BIM.

Hi as well. I just tried sample data from BuildingSMART. Works as manual import into v24. Hope distraction from vanilla work does not cause too many headaches.

From my current understanding the BCAD BIM (in this case) consists of two parts:

1#Import of geometries into ACIS objects from IFC 2x3 up to 4.1.

2#Classification of existing objects through a defined tag-catalogue.

In a current project it would be a time-saver to mass-convert incoming IFC-files to DWG to assemble a collision model (1#). Second goal would be to sync object classification <-> layer structure.

Best wishes.

@CEXT-Dan I saw the code snipped from your work. I have tried to load it with the file path correctly set. It messages as follows:

onIfcProduct 94257
<PyBrxBim.IfcImportContext object at 0x00000000030F1F40> False
True

I do not see any objects imported though. I cannot get around figuring out the usage of Bim.IfcImportReactor. Is it already possible to sideload (convert) an IFC to DWG and how would I do that? Best Seb

Hi, it's not ready yet.

I can import the sample from building smart on a local compile. However, I’m having trouble in that onIfcProductImported is never called. It’s not called in the BRX sample either. onIfcProduct is called, however, matrix = context.getLocalPlacement(entity) always returns an identity, This is also the same with the BRX sample.
I’m not sure if this is by design or if BRX has issues. I’ll work this week on filling in the gaps for importing, I expect there will be issues

I have seen the following in the SDK as well as samples\brxBimSample\BimIfcImport.cpp. Everything else is out of my league

[CEXT-Dan]

I had set new guid in
https://github.com/CEXT-Dan/PyRx/blob/main/PySamples/PyBrxBim/importTest.py

onStart, onIfcProduct, and beforeCompletion are called correctly. My guess is that onIfcProductImported has lost its “virtual” status due to some internal change. I still have lots of work on other items in BIM while I wait on the SR… I’ll make a release Thursday as a progress build

Sorry to have bothered you with this workload.

Is it somehow possible to fetch properties from Mechanical info (1#) (for example through dump functionality) and copy it into a custom BIM properties set (2#)?
Just curious to save us tons of hours.

Not sure about that off the top of my head
I noticed the mechanical sample that has access to properties. I know Bricsys has a cool properties class for vanilla BricsCAD, I have not wrapped either yet

@CEXT-Dan: Thx for the feedback. We will try ourselves with LISP standard tools for the mo. Best of health.

[CEXT-Dan]

Bricsys was able to reproduce the import reactor issue, I don’t think they will be working on a V24 fix, since V25 is just around the corner. I’ll continue working on Bim wrappers, albeit with a lower priority

[CEXT-Dan]

Seems Bricsys does not want to support me on this project. Closing until something changes
