Properties
|
property BasisCurve: TIfcCurve read FBasisCurve write FBasisCurve; |
|
The curve to be trimmed. For curves with multiple representations any parameter values given as Trim1 or Trim2 refer to the master representation of the | |
|
property Trim1: TIfcCartesianPointList read FTrim1; |
|
The first trimming point. TODO: We support only TIfcCartesianPoint, but IFC spec allows more, IfcTrimmingSelect. | |
|
property Trim2: TIfcCartesianPointList read FTrim2; |
|
The second trimming point. TODO: We support only TIfcCartesianPoint, but IFC spec allows more, IfcTrimmingSelect. | |
|
property SenseAgreement: Boolean
read FSenseAgreement write FSenseAgreement default false; |
|
Flag to indicate whether the direction of the trimmed curve agrees with or is opposed to the direction of the basis curve. | |
|
property MasterRepresentation: TIfcTrimmingPreference
read FMasterRepresentation write FMasterRepresentation
default TIfcTrimmingPreference.Unspecified; |
|
Where both parameter and point are present at either end of the curve this indicates the preferred form. | |
