Profile View Data Bands
Many customers grapple with how to set up and control the labels in the Data Bands of a Profile View, not realising that the profile set as Profile1 controls it all.
How to set the frequency of labels in a Profile View Data Band
A long section in Civil 3D is known as a Profile View and the data below the long section is referred to as Data Bands. There are a variety of Band Types that can be added to a Profile View, but the most common is Profile Data.
The frequency of the geometry based labels within a Data Band derived from a profile, is based on the geometry points of the profile specified as Profile1. Profile2 is only used for a source of data, not the frequency of labelling.
The Vertical Geometry Point Data Band Labels are inserted at the vertical geometry points of Profile1 and the Horizontal Geometry Point Data Band Labels are inserted at geometry of the alignment used to create Profile1.
The specific combination of profile and alignment geometry points to be used can be edited in the Geometry Points to Label in Band form (click > Geometry Point column > Data Band tab > Profile View Properties).
