[CE U17] Expression for Latitude/Longitude of the centroid of a Mesh?

Question

Hi all, 
 
 Our BIM deliverables requires our Mesh elements to include a Latitude / Longitude value of its centroid to be included as metadata and we are trying to use the new Latitude / Longitude Item Type Expressions to do this ( (Technology Preview) Populate an Item Type with Latitude/Longitude Properties (bentley.com) ). 
 
 The issue is that the new Expression method is looking for a Point, but we are subtracting the Range High by Range low to get our approx Centroid coordinates - eg. this.GetElement().RangeHigh.X + this.GetElement().RangeLow.X)/2)) & "," & ((this.GetElement().RangeHigh.Y + this.GetElement().RangeLow.Y)/2)). 
 
 I know this isn't a precise method, but we don't need it to be the exact value (i would love to know if we could get the actual centroid of a Mesh, but thats not critical). 
 
 Any ideas? I'm thinking I may need to put together a Point type Item Type and read that perhaps? 
 
 Regards, 
 Mark

Hi Mark, 
 I believe the method you have outlined would be suitable. Thanks for sharing this. 
 This may not work for your desired workflow/result, but one idea I had would be to utilize the Measure Area and/or Measure Volume tools with the Mass Properties option enabled. From there, you could export the results from the Mass Properties dialog (File>Save) to a .txt file and use the data from there. You could also create a point element at the centroid of the element and then create item types to use the points' XYZ coordinates, but you may have already mentioned that. 
 HTH, Jayson
