Yes, I also think FreeCAD is Very Slow in large models. ...

there is actually no case where it is necessary to work in an ifc file. if you convert it to a mesh, freecad runs fast and you can e.g. reference everything.

here to see from in 0:21

Thanks. I want 2 things:

1- unique name in my etabs and freecad model. I mean each object must be known with same name or label in two model.

2- I want to be able to edit the model (parametric model) and then export the model to ETABS.

I don't know etabs. i created a test ifc file from create simple copy of a wall. does the name of the wall arrive in etabs?

Excuse me, maybe I am wrong. I don't want to send Ifc file to etabs, because this way, I have lost many features in my model, like loads and etc. . I want to Import my model from etabs into freecad (with my importer) and then apply some change on it ( in this step freecad is very slow), and then export it to etabs (with my exporter).

ifc is used for bim processes. only the author of an ifc file changes it (usually). but not by ifc import and export but by e.g. open the fcstd or rvt or dwg file, modify it and export a new ifc file. what you describe is more of a case for step or iges

Hi Thomas:
You are correct - in practice. But it is like this because of political decision by corporates who are paranoid about people 'stealing', their Intellectual property:
IFC was a very 'slim' version of the model - given (under restrictions) to contractors etc. - with just enough info & refs for them to do their work..

But, there should be no need for us to slim the imported IFC down even further for it to work smoothly in FreeCAD.
That's an OK work-around if FC isn't performing well, but should not be the end goal.

From the point of view of designers and end-users - more, faster, prettier, is generally better.

I believe a well done ifc file is small and fast

my model is consist of 120000 area object and frames and My freecad file has about 17 Mb in size. although, it is slow in ETABS software, But in FreeCAD it is very slow that can be work with it
