Good Day

I am new to this API interface and I am not certain what are the numbers below trying to show.

I am currently testing out the Coffee Jar Thermal example as provided by SolidWorks.

2017 SOLIDWORKS API Help - Get Thermal Values at Points Example (C#)

After setting the materials to the part, there is a "Selection1 =" followed by a long line of numbers as shown below.

May I know how do I go about replacing this long line of numbers? And what does the numbers represent?

I would like the user to click on the surface instead as this will allow the program to run on various other parts rather than the Coffee Jar only.

Please do kindly assist. Thank you very much.
