Blocks on Polylines, Lines, Circles and Arcs

The ability to insert a block along a polyline is a particularly useful feature for documenting a survey and improving its representation. Starting with Analist 2024, a feature is available that allows you to insert blocks on polylines, even 3D, aligning them to the direction of the curve. The feature also allows you to number blocks with optional prefixes and document their distance from the origin.

At each node a point is inserted that can be used for subsequent tracing procedures.

Entities are inserted on differentiated layers by extending the name of the layer to which the polyline belongs. For example, if the layer to which the polyline belongs is called ROAD, the following layers will be generated:

  • STRADA_TXT contains Text
  • STRADA_PRG the progressive distances
  • STRADA_PNT point entities. In this case the layer will be inserted into a model with the same name

The entities that can be selected with the command are:

  • Lines
  • Polylines
  • 3D Polylines
  • SpLines
  • Circles
  • Arcs

The entry methods are:

  • Insertion at assigned distance
  • Insertion by assigned number
  • Insertion at vertices

The options available are:

  • Rotate the block aligning it to the trajectory
  • Insert the blocks at the end
  • Insert a prefix and optionally the progressive
  • Repeat the insertion with internodal mode, that is, the blocks will be inserted by partitioning the polyline in the elements included between the nodes

This function automatically creates a Model with the name of the polyline layer appended with the suffix _PNT containing the points that were generated at the same time as the blocks were inserted. This process simplifies the eventual extraction of coordinates for plotting with the Points features.
