how to get the gant chart from a ifc including the task entries?

bernd

found the code example to schedule analysis: https://blenderbim.org/docs-python/ifcopenshell-python/code_examples.html#create-a-work-schedule-constructing-a-building-floor-by-floor
How is the gant chart eventually created from the ifc which includes the schedule task entrys?

The gantt chat is rendered currently using jsgantt-improved, but the data all comes from IFC.

bernd

means:

• Python and IfcOpenShell have been uses to read the data out of the ifc with tasks (which has been generated with Python and IfcOpenShell)
• JavaScript and jsgantt-improved have been used to render the gant chart by the use of the read data

BTW: is there any software out there which can handle (read and/or create) task entries in ifc, apart from BBIM and IfcOpenShell?

Indeed.

Synchro, Bexel Manager, and Bill East's COBie tool come to mind. @SigmaDimensions has written a feature in IFCJS to do so too.

I tested last year Bexel Manager → https://community.osarch.org/discussion/1132/any-ifc-software-that-is-capable-of-4d-out-there-in-the-wild#latest

When I tested it, it could import the IfcTask entities, however it was a separate import. So, I lost the connections from my IfcTask to my IfcBuildingElementProxy.
