The Offset 3D command creates a copy of an entity at a specified distance from the original. Prompts consist of:
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:
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).
Select polyline
Graphically pick the polyline that is to be offset.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.
- 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.
Side to offset?
Graphically indicate which side of the original the new entity should be drawn.
