Finding center of gravity

In AutoCAD when I needed to find the center of gravity for a shape I would create a region of the shape and use the mass properties to find the C.G.  is there any way to find the center of gravity for a shape in Revit?

I belive there is no direct solution for calculating center of gravity in Revit, Though I always export my element as geometry or AutoCAD Architectural objects from Revit and then find the C.G. in AutoCAD Architecture.

That is what I thought.  I find it completely ridiculous that this program cannot give C.G.  I work with precast concrete and have to find the CG to determine how to pick up the pieces.  I don't believe that it is not possible for Revit to output this info.  The programmers just don't think that it is important. 

 

I for one could really use this feature.

Guess there might be a market for an Revit add-in for the precast detailers. :smileyhappy:

 

Post the question to the http://thebuildingcoder.typepad.com/blog/ and in the Revit programming forums.

 

Who knows, you might get lucky.

i would be interested in knowing if you ever came up with a solution.  I would like to find the CG for something with two materials such as a precast stair tower box with a flight of steel stairs on one side.  sure revit structure does know where the center of gravity is.

Never did find a Revit solution.  I have been exporting the product to dwg file and use autocrat to find E.G..  It is about all that I use autocad for any more. 

 

I still can't believed that autocad can do this and Revit can't.

This is not just a construction industry issue. Oil and Gas need C of G for steel work and platform lifting. If we cannot calculate the c of g we cannot detrmine the correct lifting points and additional steels required for placement.

AUTODESK, Please consider adding this functionality in as it is a real benefit to many users.
