## Extrusions_Rectangles

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.

  #20= IFCBUILDINGELEMENTPROXY('0ohBfsArr3ruXYxacT4yl5',#1,'NOTDEFINED',$,$,#2,#21,$,.NOTDEFINED.);
    #21= IFCPRODUCTDEFINITIONSHAPE($,$,(#22));
      #22= IFCSHAPEREPRESENTATION(#9,'Body','SweptSolid',(#23));
        #23= IFCEXTRUDEDAREASOLID(#24,#31,#25,2000.);
          #24 = IFCARBITRARYCLOSEDPROFILEDEF(.AREA., $, #26);
            #26 = IFCPOLYLINE((#27, #28, #29, #30));
              #27 = IFCCARTESIANPOINT((0., 0.));
              #28 = IFCCARTESIANPOINT((1000., 0.));
              #29 = IFCCARTESIANPOINT((1000., 1000.));
              #30 = IFCCARTESIANPOINT((0., 1000.));

## Mapped Items

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.

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
 								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.
