Offset 3D

The Offset 3D command creates a copy of an entity at a specified distance from the original. Prompts consist of:

  1. Constant/<Interval> [numerical value] Specify the desired type of vertical offset to apply:
    • Constant: Applies one horizontal offset and sets the elevation of the polyline to one constant elevation (e.g. if you measured the base of a retaining wall that sloped downhill, but the top of the wall was a constant elevation, you could offset a fixed horizontal distance to that single elevation).
    • Interval: Applies one horizontal and one vertical offset to all the vertices of the polyline.

    Based on the above, subsequent prompts that may appear include:

  2. Vert OA/Horz OA/Percent/Slope ratio
    • Vert OA: Indicate a vertical offset amount.
    • Horz OA: Indicate a horizontal offset amount.
    • Percent: Indicate a slope value as a percentage.
    • Slope ratio: Indicate a slope value as a ratio (H:1).
  3. Select polyline Graphically pick the polyline that is to be offset.
  4. Segment/<Continuous> Indicate what should happen at exterior corners:
    • Segment: Gaps in the resulting polyline will occur at exterior corners as the length of each new segment will not be longer than the source segment.

      Note: When this condition is detected, an alert box will appear allowing you options to Save Points at the segment endpoint locations and/or whether or not to Draw Segments.

    • Continuous: The intersection of adjoining offset segments will be drawn.
  5. Side to offset? Graphically indicate which side of the original the new entity should be drawn.

Note: Refer to the Command Options discussion for additional information.
