I am trying to work through the&nbsp;</SPAN><STRONG>Development Impact Analysis solution</STRONG><SPAN>, specifically the shadow impact analysis tools. I have been following the helpful video "</SPAN><A href="https://mediaspace.esri.com/media/t/1_ynv0n7fz" target="_blank" rel="noopener nofollow noreferrer">Shadow Impact Analysis Tutorial for ArcGIS Pro</A><SPAN>" on ESRI's website. However, I am stuck at step one -&nbsp;</SPAN><STRONG>Create Sun Positions</STRONG><SPAN>&nbsp;task. I have tried with my own data as well as using the exact data and parameters used in the video. No matter what I do or what data I try, I receive the same error below. There seems to be a problem with the underlying python script, receiving a "math domain" error. I have included an example output from the tool below and have only removed my username from file paths for security purposes. Help please.</SPAN></P> Wed, 31 Jan 2024 09:42:36 GMT TanaponBredin 2024-01-31T09:42:36Z Create Sun positions https://community.esri.com/t5/arcgis-solutions-questions/create-sun-positions/m-p/1376355#M1303 <P><SPAN>Hello.
