Graphic Legend R-Values

[cberg]

I am trying to develop a graphic legend that shows the R-Value, and I am getting inconsistent results.

 

I have defined the dynamic text via the wall's IFC Entity - Thermal Transmittance.

In the wall style, I have set to override the calculated R-Value.  Because I manually calculated.

For some walls the values show up correctly.  And others, they do not, and I can't figure out why.  I don't think the .1 is a U-Value, because in other walls I get random numbers. 

 

Any ideas? 

 

As an aside, walls need a dedicated record format like other parametric objects. It is very difficult to locate their data.

Try using the #WS_OBJRVALUE# worksheet function instead

Thanks @Tom W.  That seems to have done the trick.  Now I have to copy back all my annotations that disappeared when I made the change!  😖

Impressive R-Value!

I was having issues earlier.  I had to reset the value a few times before my R-Value stuck.  It finally reads 23...
