Class TIfcProject
Unit
Declaration
type TIfcProject = class(TIfcContext)
Description
Context for information to be exchanged or shared, it may represent a construction project but does not have to.
Note that this initializes property Name to 'My Project', as the project name must be non-empty (at least for conversion scripts on https://github.com/buildingsmart-community/ifcJSON and https://github.com/michaliskambi/ifcJSON ). This is the same initial project name as used by BonsaiBIM.

Description
Methods
|
constructor Create(AOwner: TComponent); override; |
|
This item has no description. | |
|
procedure SetupUnits; |
|
Setup units, following metric system and radians. This matches glTF, X3D and CGE conventions. Valid IFC project must have units defined. BonsaiBIM expects it. See also valid notes on https://stackoverflow.com/questions/51665572/required-data-for-ifc . | |
|
function ModelContext: TIfcGeometricRepresentationContext; |
|
Find a 3D TIfcGeometricRepresentationContext called "Model" in the project. This should be used to add all new 3D models to the project. Returns Call SetupModelContext to make sure this is non-nil. | |
|
function PlanContext: TIfcGeometricRepresentationContext; |
|
Find a 2D TIfcGeometricRepresentationContext called "Plan" in the project. This should be used to add new 2D plans to the project. Returns | |
|
procedure SetupModelContext; |
|
Add a 3D geometric representation context named "Model" to the project, which should be used for models displayed in 3D view. Does not add it if the project already has a suitable 3D context with this name. Makes ModelContext non-nil. | |
|
function BestContainer: TIfcSpatialElement; |
|
Find TIfcSpatialElement where it seems most suitable to insert new elements. This is just a guess, a proper IFC editor should allow user to choose it, as there may be multiple valid choices (e.g. TIfcSite, TIfcBuilding, TIfcBuldingStorey). Returns | |
