Extracting Extended Property Values

All,

I have a drawing that was exported from another app. I need to extract the contour elevation and then place it as mtext on the contour. Normally I would use objectextensions.getparameterbyname however this parameter isn’t showing up. Anyone know how to get these “extended properties”?

In what kind of extended property is the elevation stored in? Is it a property set or something else?

Hi Patrick,

It’s under normal properties but extended in “OD: TestPS” at the bottom left of my snip. I am looking for the “Contour” value in particular.

Hi Pillay!

Those nodes unfortunately didn’t make it into the 2025.1 release and are hopefully added at some point but if it’s okay for you to use an older version, you can find dedicated nodes in the Civil3d Toolkit:

Edit:
Use “Select Objects” instead of “Select Object” to select all contours. “GST_Muerz” is equal to “TestPS” in your example, “GNR” is equal to “Contour” in your example.
