Hi, I used IfcDoc to develop a custom mvd for testing purposes, which right now contains only IfcDoor entity. My question is : How can I use my mvd to export for example in Revit (or other software) to be able to see the results of it. (In Revit I cannot find a place to put exp,xsd or mvdxml files to see them in the Ifc export menu) Do you have any suggestion regarding Revit or may be other softwares, for that matter,that I can use? Thanks , Kaveh ---

Hi @KavehAll , as far as it is known to me, there is no software currently available that would support this kind of setting up the export. But I do like to hear that there are other people in the world with the same idea! Perhaps we can collaborate on that? PM me. ---

@stefan.markic This is why I’m building IfcXtreme ([GitHub - IfcXtreme/IfcXtreme: The next generation of IfcDoc](https://github.com/IfcXtreme/IfcXtreme)) In the near future, there’s a need to have a tool “INSIDE THE SOFTWARE” to control and manage Data/Information/Knowledge Exchanges > [@IfcX and IfcLite projects](https://forums.buildingsmart.org/t/ifcx-and-ifclite-projects/1440/17): > > Concept study: Which one is better, the approach IfcDoc follows, or the approach IfcXtreme fallows which is based on Visual Programming and Node-based approaches, and X-based too There are other projects like IDM Toolkit too ([IDM Configurator/Toolkit/idmXSD/IDM Schema](https://forums.buildingsmart.org/t/idm-configurator-toolkit/380)) However, IfcXtreme even is some steps ahead ---

The GeometryGym IFC tools allow you to build up an IFC using visual programming, giving you a very fine-grained approach toward creating an IFC with exactly the data you need. The [BlenderBIM Add-on](https://blenderbim.org/) allows you to create IFCs using a nearly identical internal data model to the IFC schema, again, allowing you to have very fine-grained control over exports. Additionally, the IfcPatch tool and BIMTester tool allow you to modify IFC files to exactly the data you require, and validate it in a more flexible and easier manner than using mvdXML. However, it lacks the ability to currently build up an export of specified entities. This is something I do have on the to-do list, however. So you can expect it in a future release of the BlenderBIM Add-on. ---

GeometryGym is not like IfcDoc or the next generation of IfcDoc, something like what IDM Configurator/Toolkit follows @Moult Dion, you clearly know what I’m talking about and what I’ll build BlenderBIM, BIMTester, IfcPatch, Git, GitHub, etc are good and invaluable, however, I see some hidden things that few can see However, just time can show which solutions were right and followed the right path
