Controls

Control	Description
Alignment	The alignment that will have section markers applied.
Start Chainage	Insert the alignment chainage where you want to start adding section markers.
End Chainage	Insert the alignment chainage where you finish adding section markers.
Interval	Select the checkbox and type the interval to add interval section markers.
Horizontal key points	Select the checkbox to add section markers at key points along the horizontal alignment.
Vertical key points	Select the checkbox to add section markers at the selected long sections start and end points, changes in grade, and curve tangent points.
Vertical sag/crest points	Select the checkbox to add section markers at the selected long sections crest or sag points.
Long Section	Select the long section to add the section markers to.

Notes

Click OK to create section markers.
Interval section markers are created at chainages that are a multiple of the interval.
Intervals are computed using the current units and distance type.
Add section markers after the design of your horizontal alignment is complete.
If you do edit the alignment, you should review all section markers. The following edits to section markers may occur:
- Interval section markers retain their chainage and are moved to the correct location on the edited alignment.
- The chainage for horizontal section markers are recomputed. You will need to add new section markers for any new key points in the alignment.
- Removing a key point in the alignment will delete the section marker associated with the vertex.
If the alignments chainage equation is edited:
- Interval section markers chainages are updated and the location on the alignment is unchanged.
- Horizontal section marker chainages are recomputed.
- Vertical key point and vertical sag/crest section marker chainages are recomputed.

Possible errors

Error	Description
Duplicate Chainages	There is more than one location on the alignment with the specified chainage. Select the distance along the alignment where you want the section marker created.
