i got all these . I am now working to convert my old python 2.7 code to python 3.6. will be back soon if problem comes

Download from here for windows 64bit http://www.ifcopenshell.org/python.html and i extracted the file and paste here on my laptop C:\Python27\Lib\site-packages and then simply import ifcopenshell in python Please tell is this write way to work or not

How to extract these invese relationships entities. i am using python 2.7.14 and ifcopenshell of 2.7 ones i had also used versions 3.5 but it doesnot work good for me.

I agree with you , BUT add() is not working like this . it copied the tree link but misses some entities like IFCPROJECT is linked with IFCSTYLEDITEM IFCRELAGGREGATES IFCRELCONTAINEDINSPATIALSTRUCTURE IFCRELASSOCIATESMATERIAL But donot extract these entities , so to extract , i had to again call them again seprately by add function and then repetetions occurs.

I am also using the same thing. It extract the single entities or multiple that i want but that new .ifc file is open with error or empty model. Because many enties are printed multiple times as the extracted enties print all its tree entiries with it. example IFCOWNERHISTORY also extract IFCPERSON and IFCPROJECT also extract IFCPERSON and many more like this

Started a new work and need help. Read .ifc file using IFCOPENSHELL and python and from .ifc file i want to extract some enties Example: Orignal ifc is having 4 column and 4 beam , and wanted to extract 4 column and print then to new ifc file so that when i open newIFC file in any viewer it must contain only 4 column. orignal ifc is attached.

i also studied this but it is not helping to write ifc file. it is just telling how to extract data from ifc file.
