Arrows reflect grade; elevation and grades update as modified.
The secret is an expression that was created to allow the direction arrow to rotate.
The default label style should look like this after placing labels on a feature line with elevations.
Detailed information from Autodesk
Now that we have found the default style let’s elaborate by adding elevations.Copy the current style and rename it ELEV & Grades. Add a text component.
Configure Anchor Point to the Start of each feature line, add the elevation to the start segment, rotate it 90 and set an offset.
The new style should include elevations. Make sure you repeat for curve labels.
Now it’s time to have some fun with this style by adding markers and moving the arrows to the lines.
Modify the design and watch the elevations, grades and slope arrows automatically update. Add Sincpac (3rd party software and link the points to the feature lines.)Please look for future post as we discuss this style, and other solu-arounds for site grading.
Shoot me an email and I will send the completed style to you. Should be posted on ADSK Solutions website soon.
