One Vertical Curve for Sag and Crest

To have one style for sag and crest vertical curves with and without high and low points. So you can just have on main label style for sag and crests.

  • Add a line to the label. Set the Start point anchor component to the Anchor Curve High Point and the End Point Anchor to the Midpoint of the Dimension Line. Give the line a name so you can remember what it does.


  • Next create a line construction line which will be hidden in the style, but will help rotate the text parallel to the dimension line. It is needed because we have to tie to the previous line created and have a way to make it look like the other text in the label. If you skip this line then it will be nearly impossible to get the rotation right as the label is moved up and down.


  • Next add the text to the label for the HP. Use the anchor point of the start of the construction line you created in the last step. Add whatever text you require for the HP.


  • Here is a picture of how the label looks.


  • Just change the visibility of the HPtoMidDimensionLine and the ConstRotationLine to false so it not seen in the final style.
  • Repeat the steps for the low point, using different names for the components.
  • Since the low point and high point portions of the label are anchored to the low or high point the those portions of the label won't show if there isn't a high or low point of the curve.

    I have also uploaded the HP portion of the label here.

Hi remember me?

This tip is great, except our office likes to have all the sag callouts to be above the profile geometry and the crest callouts below it. So because of this we still need to have 2 different styles.

Nice blog site...I'll be visiting here more often.
