procedure AddMeshRepresentation( const Context: TIfcGeometricRepresentationContext; const Coordinates: array of TVector3; const Indexes: array of Integer; const Solid: Boolean = true); |
|
Add mesh representation to the given product. The mesh is expressed as a set of 3D points (Coordinates) and indexes to these coordinates (Indexes) that determine polygons. The indexes are 0-based and can be separated by -1 to delimit polygons. See examples/ifc/ for an example usage of this routine to define walls and floors. Parameters
| |
|
procedure AddBoxRepresentation( const Context: TIfcGeometricRepresentationContext; const Box: TBox3D); |
|
Add box representation to the given product. Right now, the Box is transformed into a proper mesh representation, so this is just equivalent to calling AddMeshRepresentation with the 8 box corners and proper indexes to define 6 box sides. | |
|
function TransformSupported: Boolean; |
|
Does ObjectPlacement express a 3D transformation we can handle and Translation reliably gets and sets it. | |
|
procedure SetTransformRelativeTo(const OtherProduct: TIfcProduct); |
|
Make Translation of this product relative to a given different product. This sets TIfcObjectPlacement.PlacementRelTo underneath. | |
Properties
|
property Translation: TVector3 read GetTranslation write SetTranslation; |
|
Translation of this product.
| |
|
property ObjectPlacement: TIfcObjectPlacement read FObjectPlacement write FObjectPlacement; |
|
Object coordinate system and placement of the product in space. | |
|
property Representation: TIfcProductRepresentation read FRepresentation write FRepresentation; |
|
Representations of the product. | |
|
property PositionedRelativeTo: TIfcRelPositionsList read FPositionedRelativeTo; |
|
