I am trying to find the center of gravity for a generic model family I use for self perform concrete. I am having a little trouble getting the script to work. The list shows up “empty”. When I do it on a wall it works fine, so I am not sure what I need to change in the family or the script for it to…

Can you share that family? The issue lies in the fact that Element.Geometry is not working on that family and we (the community) might be able to diagnose it or come up with a different method of getting the info out of it. Does it have nested families? Are there Cad Imports or Meshes inside the f…

This is likely caused by a bug that was recently fixed: [aparajit-pratap] Add null check for Revit geometries that fail to convert to Dynamo geometries in Element.Geometry by aparajit-pratap on 09:47AM - 28 Jun 17 27 commits changed 5 files with 55 additions …

The bounding box won’t get you the center of gravity which is weighted by the volume and placement of the element. In the example image, the center of gravity would be offset towards the railing and upwards from the bounding box center.

True. I’ve only used the bounding box centroid to determine element locations for Revit elements that don’t have a location property. If it has to be the center of gravity and the Dynamo geometry library won’t give you what you want, you could try the Revit API. You can get all the (Revit) solids i…

I forgot about mass of the element! Yeah… lots of math.

I did a little thing here: http://jbdynamo.blogspot.no/2016/12/ammo-centre-of-gravity.html?m=1 if it could be of any help. It requires a density as a physical property in the elements materials since I was using it for both concrete and steel elements all at once. Do your family have any nested fami…

Hi @bradwitt , Lately i have also been experimenting with this simple method. I found it here: https://www.linkedin.com/pulse/center-gravity-dynamo-jason-murray For one element (precast concrete) it seems to give the correct center of gravity. I’m not sure if the below graph creates the right ce…

Thank you all for your help, this helped. I have to go back through the nested families and check to see if they were built correctly, but for the most part it seemed to work!

You can also check this. Move by vector : see below thread "zwaartepunten.dyn Edwin

Hi Mate, How it can be if i just want to do it for one wall ? Cheers
