Civil 3D Jewels

A brief discussion concerning marker styles...

Marker styles are Civil 3D jewels that can used for emphasis in other display styles.

  • Alignments can possess markers. Various marker styles can be assigned at different types of horizontal geometry intersections and other points of interest on alignments. Profiles can possess markers. Various marker styles can be assigned at different types of vertical geometry as well as vertical points of interest on alignments. Both alignments and profiles have a Markers tab that can be used to configure styles to these locations.
    Marker styles are assigned to codes sets to delineate the locations of intersecting links which can be very important when constructing an assembly.
  • Marker styles can be configured to feature line styles for projection into views.
  • Survey network styles use marker styles to delineate types of points observed in the field.
  • Survey figure styles use marker styles to illustrate various points of interest along an observed linear feature.
  • Marker styles can be configured to interference styles to mark where pipes are in conflict.
  • Marker styles can be assigned to certain types of labels that are not a part of a label set.
  • Marker styles can be selected at time of label creation.
Marker styles can be configured as you would AutoCAD points using the DDPTYPE command. Alternately, marker styles can use blocks. Either method allows you to scale the marker to a plotted height or a specified scale. Property overrides on the Display Properties tab do not affect styles using blocks as markers. Any property overrides for marker styles using blocks must be made in the block definition itself.

I recommend the use of separate marker styles if the same shape is being utilized in multiple styles. For instance, if a circle is being used in both an alignment style as well as an assembly code set, use two separate styles so that you can scale them independently of each other.
