What type of GDL Objects can be created with RFA & RVT Geometry Exchange Add-on? Objects, Doors and Windows can be created. IFC is still the route we encourage users to take if they need full model exchange between any other software. It is not intended to compete with IFC any more than DWG/DXF or Sketchup™ compatibility does. The RFA & RVT Geometry Exchange Add-on extends Archicad's ability to collaborate with Revit users and solutions.

Filter the model content during the import process Use the survey point dataĭoes the RFA & RVT Geometry Exchange Add-on compete with or set back OpenBIM or the drive for IFC? OpenBIM is about being open.

Carry non-element information (project hierarchy, element assignments etc.).

Carry profile or composite information of a structure.

Place associative dimensions on the linked elements.

Conversion to real parametric BIM elements.

Features that IFC can provide over the RFA & RVT Geometry Exchange Add-on: wall, slab, grid etc.) from a Revit element by keeping several properties intact. The RVT interface imports geometry information which is very limited for post processing in the Archicad project – with primary purpose being on coordination. Using the IFC format for data transfer you can create native Archicad elements (e.g. IFC is a better format if you need more intelligence. What are the major differences between linking RVT and IFC files? You can check the detailed and informative FAQ on our website: Look for File > Interoperability > RVT Export in a 3D view

exporting the 3D model geometry directly into the RVT file format.

Look for File > External Content > Place Hotlink)

hotlinking 3D model geometry from RVT project files (RVT format will be available when adding a new hotlink module).

Look for File > Libraries and Objects > Import RFA as GDL Object)

importing 3D geometry from RFA object files and creating GDL objects.

The three Revit Exchange functions are described below:

BIM Store, NBS Library, MEP content) which mainly focus on delivering Revit families.

A number of BIM libraries are creating GDL object, which are available, we have a summary page on our website, but there are some out there (e.g.

RFAs, so Revit families are similar to our Objects, they can be loaded into the file or saved externally.

Probably the one of the most common scenarios is that the engineers will send an RVT file (instead of an IFC), Revit's native project format.

It's unlikely that we should need receive a Revit project template or a Family template, so let's focus on the ones that we need to be aware of: What kind of files could we receive from an engineer working in Autodesk Revit®? It has 4 file formats of its own: RTE (template), RVT (project), RFT (family template), RFA (family).
