Floor, Ceiling and Roof Conversion Rule

Define a rule for converting an IFC floor, ceiling or roof to Vertex BD floor, ceiling or roof.

Converted ifc types

Select the ifc types for which this rule will be used:

• IfcSlab
• IfcRoof

Conversion

Click Select, and select a structure from the floor, ceiling or roof library to which IFC objects of the selected type will be converted.

The name of the library and structure is updated in the dialog box.

A) Offset

Enter the distance of the top surface of the frame layer of the structure from the top surface of the IFC object.

• A = 0 - The top surface of the frame layer is at the same height as the top surface of the IFC object.
• A < 0 - The top surface of the frame layer is below the top surface of the IFC object.
• A > 0 - The top surface of the frame layer is above the top surface of the IFC object.

Frame thickness from IFC model

When the feature is selected, the thickness of the frame layer of the structure is determined by the thickness of the IFC object. The thickness of the other layers is consistent with the selected structure.
