Re: use ifcGrid in Axis System
Would you like to create a axis in FreeCAD and export as IfcGrid or would you like to import a IfcGrid from ifc into FreeCAD and use it as axis object in FreeCAD?
Re: use ifcGrid in Axis System
I assume this one ...
There is no need to tell a FreeCAD axis system it should be IfcGrid. All this is done in background and axis should be exported in IfcGrid. But it seams there are problems ... There is some IfcGrid in ifc but neither zoom nor vision does show the grid system ... examples attached.
Someone with special ifc knowledge around? What is wrong in the ifc with the IfcGrid?
Re: use ifcGrid in Axis System
this one works ... Do not ask me why, I have no idea ATM ...
Re: use ifcGrid in Axis System
Hi,
I want to transfer axes from FreeCAD to IFC and wanted to specify the IFC type.
In the second step I noticed that if I have an axis system, the type ifcGrid is automatically used during the export and is cleanly entered into the ifc file.
But in the properties of the grid the IFC type is not shown.
With single axes no export takes place.

Re: use ifcGrid in Axis System
you will not believe it ... One needs to add at least two axis objects to the axis system to get the whole axis system exported to ifc. Watch in the report text. The axis object must be written on exported objects ...
Re: use ifcGrid in Axis System
It seams IfcGrid need to have two axis sub systems ... I am not 100 % sure if the problem is ifc standard or IfcOpenShell, but if None is passed to IfcOpenShell for v it returns an error. https://github.com/FreeCAD/FreeCAD/blob ... FC.py#L502

Re: use ifcGrid in Axis System
The axis system does not need to be part of the IfcSite, but do not forget to select the axis syste on export if it is not Part of the IfcSite.
Do not forget ot switch debug messages on in IFC preferences to get the warnings on report console.
