Visual query language

This page explains a visual query language. This will not necessarily become a real way of quering BIM models, for now it serves as tool to develop/explain the new query language.

Current considerations

• Remove the "Root" node, if you consider all the blocks with no input's as starting points, there is no need to have a "Root" node.

Examples

Query a list of GUID's

Query multiple types

Query name property

Query AND + Comparators

This will return all IfcWall objects with a OverallWidth > 2 AND OverallHeight > 3

Query NOT + null

This will return all IfcWall objects that have a Representation

Query IFC properties

These are not direct object-properties, but properties that are attached to the object via IfcPropertySet/IfcPropertySingleValue etc...
