After installing IFCout for AutoCAD Plant3D, the following ribbon appears in AutoCAD main ribbon:
Allows you to specify the current drawing file linear units. IFC exports in metric millimeters. It is important to make sure that you specify the correct units of the drawing you want to export
Allows you to filter out specific entity types to export. The default is all types as shown in the dialog to the right. You can check or uncheck the types you want to filter out. Uncheck types will not be exported while check types will be.
This is a visibility control tool. You can Isolate, show and hide entities in the current drawing file based on either its type or line number. After that you can use the IFCout export tool (see below) to only export all visible entities. Click <Isolate> to isolate entities specified either by its type or line number or both. You can do the same for <Hide> and <Show>. <Show All> shows all entities in the current drawing. You can also specify whether to include steel members or just the piping components. <Show Steel Members> or <Hide Steel Members> will only show/hide steel members.
This dialog allows you to export current opened drawing to IFC format file. <Browse> navigates to where you want to specify the location and IFC file name. "Export Options", allows you to specify whether you want to export all entities in the drawing, select entity from the graphic screen or only visible entities. "IFC format", allows you to specify the version of IFC you want to export to. It is recommended that you make sure that all specs referenced by the entities you want to export are currently loaded in the drawing. Also blocks/block references will not be exported. If you want to export blocks/block references, you must explode/bind them first, after you do the export, you can undo the explode/bind or simply do not save the drawing. Please see video below "Export"
This dialog allows you to export more than one drawing files into a single IFC file. navigates to where you want to specify the location and IFC file name. <Check All> allows you to check and uncheck all files in the project file. <Run for Selected Files> starts the export process for all checked drawing files in the list. Please see video below "Export All".
