[Equest-users] How to import 3D model

[Sivakumar, Sudheera]

What do you guys think about how to tackle the situation , when the Architect changes the floor plan considerably in the middle of the project design and not enough budget available to create the model ( 7 storey building with different floor plates)  from scratch in the wizard? Going through the messages, creating from scratch is the best option. Am I wrong?

Thanks

I like this conversation cause it is one that I have battled with for a long time.

I'm going to respond on top of the previous comments in saying that it all depends on your comfort with software and 3D modeling. As below I agree with Vikram that at the moment it is easier to just model the project directly in eQuest and not import at all. Let me however tell you that I have built models in eQuest, Vasari, REVIT and Ecotect and they all work fine as long as you understand the basic principles of computer modeling. Vasari is definitely not ready for prime time however you can use it as your integrated modeler between eQuest and REVIT.

The one main issue that I have run into and it is working as an architect and coordinating with our engineer that I have found out that architectural REVIT models with gbXML information looks totally different than the zoning model for an HVAC layout used in eQuest. The ways these models are constructed are total different even though the exterior skin might look the same.

I've done this before but I have attached images of all the softwares to show the model.

Just stick with the wizard for now unless the geometries are extremely complex.

Thanks,

PETER HILLERMANN

I agree. The argument is that with importing from Revit there is already a 3d model available. The issue normally is that there is too much information in the Revit model and most often it needs a LOT of clean up. Its potentially easy if you are a person with really fantastic model management skills (I haven't met one yet).

One potential workflow is Revit > Ecotect > eQuest.

If you google exporting Revit to Ecotect there are several videos / step by step instructions to show you what you need to do to prepare the model. It mainly has to do with how you define rooms, which become your thermal zones. However, Ecotect to eQuest I haven't been able to do very successfully. There seems to be some problems with exporting the geometry and zones properly (which is really the major and some would say only benefit). The only thing I was able to import were wall constructions, which I would rather define in eQuest anyways. I haven't been able to find a thorough explanation of what to do in Ecotect to prepare your geometry for eQuest. FYI, Ecotect also exports to gbXML, Energy Plus, Radiance, etc.

Another workflow is Vasari > eQuest. Vasari is an, as of now, free Autodesk program in trial stages that is basically Revit combined with some basic DOE2 based energy modeling capability, really just for comparing different scenarios in early design. In my opinion this software is not ready for creating more complex models as I found creating the zones lacks the flexibility most models would need - The software will automatically create zones based on ASHRAE 90.1 perimeter set backs, 1 per floor, etc. Unless you have an open office plan, this is probably not what you need. You can define your zones manually, but not easily in my opinion. http://labs.autodesk.com/utilities/vasari/ - if you're interested.

I've tried to look into this a few times now, and all things considered it seems that importing 3D geometry is not that big of a timesaver compared to the design wizard, if at all. If anyone has experience with these workflows, I would be grateful to hear it.

hi

Happy New Year to All. Does anybody know the any software from which we can import 3D model into eQuest.


thanks
