    Thumbs up Expression for setting min and max profile grade labels. C3D 2012

    I have an alignment that has lots of grade breaks. I want to only show grade labels on the profile with slopes of 3% or >. Is there an expression that I could use to represent this? Could someone please help me out? Thanks

    Create an expression that sets a value to use as the text height, 0.0001 for flat slopes, and, for an Imperial drawing with normal text height of 0.10", 0.1/12. Then use this as the text height value in the label style.
    IF(ABS({Tangent Grade})<0.03,0.0001,.10/12)

    You may need to adjust your ambient settings to allow the label to use the precision shown in the expression above.
