Set a Line Elevation
Apply a single, constant elevation to a 2D line to make it a 3D linestring. You can also specify a vertical offset from the elevation that you enter and a surface to which the linestring will be added.
Note: You cannot set a line elevation on a line that already has elevations. To modify the existing elevations, add vertical control points using the Edit Linestring command.
Tip: The Set Line Elevation command is especially efficient when you have annotations that contain elevations next to your lines. You can simply pick each object and annotation consecutively.
Tip: If you need to apply the same elevation to multiple consecutive linestrings, you may want to join them into a single linestring first using the Join command.
Prerequisites:
- CAD polyline, circle, arc, polygon, or linestring to elevate
To set a constant elevation on a linestring:
- Select Set Line Elevation in CAD > Edit.
The Set Line Elevation command pane displays.
- To apply a standard vertical offset to each elevation you enter, type a value in the Vertical offset box.
Note: This can be especially helpful when elevation values are specified by clicking on a text object, and when the resulting value is to be above or below the elevation reflected on that text. This commonly occurs in setting building pad elevations where the finished floor elevation is labeled, and the top of pad is to be beneath that by a specified slab thickness.
- To make each line you pick a member of a specific surface, select the surface in the Add to Surface list. Otherwise, leave the surface set to <None>.
- Pick a line that you want to elevate in a graphic view.
- Pick another elevated object, such as an elevation annotation or contour line, to apply its elevation. Alternately, you can type a value in the Elevation box and click Apply. Any CAD line or polyline that you elevate is converted into a linestring. The elevation is applied to the entire linestring after adding the specified vertical offset.
- Repeat steps 4 and 5 to add elevations to additional objects as needed.
