Autodesk Release Revit globe link plugin

I have finally got around to overhauling my blog and will hopefully be far more proactive!!!

Anyway, for those of you who can remember as far back as April this year, you will remember that Autodesk promised a Google Earth plug-in when Revit 2008 was released. After some delays, they have finally got around to releasing it. It is only available for Subscription users and you will need to download it from the Autodesk Subscription Center.

I've taken a look at it and it is very good. You can have the ability to import a Google Earth image into directly into Revit. This allows you to sketch over the top of this image, using it as a guide. You can then be assured that any geometry you place in relationship to the image will get passed back directly into Google Earth in the correct location. This is very similar to the way Sketchup and Google Earth work. In addition to this, you can export a KML/KMZ file from Google Earth and then import this into Revit and it will realign the project location with Google Earth location. You can then publish model from Revit back into Google Earth.

Also,when you publish your model a dialogue box appears which allows you to control which categories are passed back to Google Earth, which is helpful. In reality, if you have a large model you will not want to publish the whole model as its likely to push Google Earth over the edge! You may want to consider either setting up worksets or filters to the control any geometry you pass back to Google Earth.

Does the Google extension only work for Architecture or is it available for Structure. I can't see it on Subsrciption Site

HI David, been trying a few things with the ol Revit / Google Earth tie plugin. One thing i've noticed is...I have a Revit job thats been tied to coordinates from actual AutoCAD survey drawings, everything works fine with regards the tie in between the Autocad and Revit, it should do it's been set out on site.
You would therefore expect the Exported KMZ to be in the 'zone'.
I published the KMZ from the accurate Revit SITE model.
The Coordinates for the job are correct in terms of Surveyed information ( National Grid ) This would place the job in South Lanarkshire about 20 minutes from Glasgow, the Published KMZ when you bring it into Google Earth is in Fulham, London :)
So there must be diffrences in the coordinate system, i don't expect it to be in the same accuracy as Autocad, but you would think maybe a bit less that 600 miles adrift...

Great plugin though! Works actually very well when you 'acquire' from Google Earth, model, then export back out the KMZ into Google Earth...

Great wee further highlights the power to achieve a quick study.
