Added second roundtrip test with non-vertical extrusions
2020-05-13 12:40:51 +00:00
# IFC roundtripping specifications
moved file naming conventions to markdown
2020-05-17 23:46:39 +00:00
This file lists "exercises" to be performed by a BIM application to achieve adequate round-tripping with IFC files. The application should successfully complete all the steps.

# Tests

Made separate tests for extrusions with arcs, circles. Relabeled 'Extrusions' to 'Extrusions_Rectangles'.

## Extrusions_Rectangles
Added second roundtrip test with non-vertical extrusions
2020-05-13 12:40:51 +00:00
The application should be able to export and import an IFC file containing three IfcBuildingElementProxy entities, each with one representation, which is an IfcExtrudedAreaSolid, each based on IfcArbitraryClosedProfileDef made of an IfcPolyline, like the example below. One profile should lie on the XY plane, one in the YZ plane, and a third on a plane made of one of the former rotated 45° along the Y axis. Extrusion directions should be normal to the profiles.

## Mapped Items

2020-05-23 23:46:46 +00:00
Mapped Items, which go by many different names in different BIM apps (a few called out below), are objects where the definition of one object is connected to another. That is, if one istance is modified, these changes will also be reflected in other connected or linked instances.
