I recently implemented the IfcSpaceZoneBoundaries add-in to link in and analyse IFC file zones and spaces, then prepared it for use in Forge Design Automation. Now I want to add level information to the CSV export. However, the
DirectShape elements created to represent the rooms and zones have no valid level assigned, so their
Level property is invalid.
Happily, we can easily analyse the BIM and generate the equivalent information ourselves
– Retrieve levels sorted by elevation
– Determine level from element elevation
– Carl Bass and Zoox autonomous vehicles
– Physical reasons to be happy to be alive...
