If you have a list of location points in Excel then it should be relatively simple - providing your family has been modelled in the correct way.

The insertion point (Crossing of the Reference Planes in the family) will pair with the points list you have. Bear in mind however that the coordinate system logic behind Dynamo and Revit differ somewhat. The 'Project Base Point' is in fact 0,0,0 (XYZ) and matches to the 0,0,0 (XYZ) in Dynamo. So you may need to do a little math if the coordinates are based off your Survey Point.

After that, simply look at Excel.ReadFromFile, a little math operations after pulling the Survey Point and Project Base Point double values and look at FamilyInstance.ByPoint.

I created a complete script at work to extract....It ran as expected.

• I ran it at home the very first node, Element.location is returing all null..

• Drove me nuts thinking I had done something wrong/different
• I ran it again at work next day and works 100%

Same Programs on both..Revit 2015 r2 + Dynamo 1.2.1
Work is on Windows 7... Windows 10 at home
What could be causing this issue?
All help is greatly appreciated.

If you're trying to automate repetitive tasks, please I would love to hit a link to a good intro YouTube channel or website. Thanks for posting! Cheers,

Try using the in-built Element.GetLocation​ node instead.
