Hello,Robert.
I've successful displayed the annotation in DV after reading the URL you sent to me. Thank you!
But this rule is used in the Architectural tab in Reference Presentation dialog. I am confused why the rule which is added in the Structural tab doesn't work even though "Beam" belond to the "Structural“?
If I use DEMTools(Drawing Extraction Manager) in the menu "Building Designer", the Structural rule take effect but make a error value like the length of "0.00000", Why?
