IFC type for ADA clearances
Anyone know what ifc type the following 2D ADA clearances could be categorized under?
I thought IfcVirtualElementType, but IfcVirtualElement doesn't have a type.

They should be part of the type's Clearance representation.
Maybe IfcTypeProduct with

IfcAnnotation/LINEWORK
as the ApplicableOccurrence?IfcTypeProduct
doesn't show in the list, however...What's wrong with the Clearance representation?
Potentially, but what's the ifcclass then? I'd like to type these.
Oh, i think i know what you're talking about... about putting them in the particular type that applies.
I'd rather not do this, as I typically don't want clearances in every ifcdoortype, for example, I have in the document. Would clutter the drawing.
I use these clearances, more in the design phase, and move them around individually, just to make sure there's enough room around doors, furniture, appliances, etc.
Currently i assigned them to the IfcTypeProduct, but I can only use this in one drawing, at a time.
There's also
IfcBuildingElementProxyType
withPROVISIONFORSPACE
as the PredefinedTypehttps://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/lexical/IfcBuildingElementProxyTypeEnum.htm
Correct, that would be good, except that there is unfortunately no IfcVirtualElementType :(
Really should fix IfcTypeProduct. Edit: fixed https://github.com/IfcOpenShell/IfcOpenShell/commit/a360bac4c3ca0138becac7acf5fd8e2ed1232be8
