Miscellaneous Commands

Various utility commands available in R3Survey.

R3COPYPOLYLINESEGMENT — Copy a single polyline segment

Command: R3COPYPOLYLINESEGMENT

Copies a single segment (line or arc) from an existing polyline as a new standalone entity. Useful when you need to extract one boundary leg for use elsewhere without exploding the whole polyline.

Usage

  1. Type R3COPYPOLYLINESEGMENT
  2. Click on the polyline segment you want to copy (click near the segment, not a vertex)
  3. Specify a base point
  4. Drag and click to place the copied segment — repeat to place multiple copies
  5. Press Esc to finish

R3REMOVEDUPVERTS — Remove duplicate vertices

Command: R3REMOVEDUPVERTS

Removes coincident (duplicate) vertices from a 2D polyline — vertices where consecutive points occupy the same location, creating a zero-length segment. These can cause issues with area calculations, offsets, and export.

Usage

  1. Type R3REMOVEDUPVERTS
  2. Select the polyline to check
  3. R3Survey reports how many coincident vertices were found
  4. Confirm Yes to remove them, or No to leave the polyline unchanged

R3REV — Reverse line direction

Command: R3REV

Reverses the start/end direction of a selected line or polyline. Useful when an entity was drawn in the wrong direction and needs to match bearing conventions.

R3TRANSFORMSURVEY — Align survey using MARK points

Command: R3TRANSFORMSURVEY (Civil 3D only)

Transforms (translates and rotates, no scale) the drawing to align with known control points. Reads two or more CogoPoints coded MARK and uses them to compute the required transformation. Useful for registering a survey to control.
