IFCs with "sharp" triangulated faces cannot have spot elevations or spot coordinates

6

Revit cannot assign psets to site without having a topography object

1

It is not possible to implement the IFC2X3 georeferencing guide by buildingSMART in Revit - i.e. to assign a Pset_MapConversion and Pset_ProjectedCRS to the IfcSite element, without first creating a...

Revit can export many IfcSite objects that aren't creating the spatial hierarchy

1

If an object in a file, say a bollard or street furniture, is assigned to the Revit site category, then an IfcSite entity is created for it on export. In...

In IFC4, Revit still uses deprecated IfcPresentationStyleAssignment and doesn't support IfcPresentationStyle

2

It should use `IfcPresentationStyle` instead. This means that IFC4 exports from other BIM applications, when imported into Revit, do not have colours. It also leads to invalid IFC4 exports which...

This is used in the majority of Nethack ttyrecs. There's a thing called https://en.wikipedia.org/wiki/DEC_Special_Graphics where if \e(0 is sent, it toggles some codes. Steps to reproduce: ```python import pyte screen...
