Issue

User can insert a .dgn or .sat file using Place Imported Shape from File command in Equipment & Furnishings task. This creates a shape object under the selected Equipment. Using .NET API, when user tries to copy this imported shape using a copy constructor of GenericShape class, the following exception is thrown.

Sample Code:

Dim oShape As GenericShape

‘ TODO: initialise the object to the Imported shape object that needs to be copied

Dim oNewShape As New GenericShape(oShape) ‘exception is thrown at this line of code

Exception Message:

Unexpected failure in constructing the .NET object

Environment

Smart 3D version 2014 R1 and earlier

Resolution

Use the following sample code as the workaround to copy the imported shape. Get the filepath of the imported shape file and give that path as input to the GenericShape constructor to create a copy of it. Make sure that the corresponding file exists in the filepath location.

Dim oDestinationEqp As Equipment

‘TODO: initialise the object with the Equipment object

Dim sFilePath As String = oShape.GetPropertyValue(“IJUAImportedShape”, “FilePath”).ToString()

Dim oNewShape As New GenericShape(oDestinationEqp, sFilePath)

oNewShape.Origin = oPosition

‘TODO: initialise oPosition variable to the required position in the 3D model
