Add a full, fixed circle defined by a specified pass-through point, direction at the pass-through point, curve direction, and radius.
The result is a circle with four pass-through points. The entity position is not affected by edits to adjacent entities.
Tip
You can use transparent commands when you are prompted to specify direction, radius, or length, or use station offsets to specify any points. For more information, see Transparent Commands.
To add a fixed curve (through point, direction at point, and radius)
- Click the alignment. Click Alignment tab
Modify panelGeometry Editor
. - On the Alignment Layout Tools toolbar, click
Fixed Curve (Through Point, Direction At Point And Radius). - Specify the pass-through point.
- Specify the direction at the pass-through point or specify a bearing or azimuth.
- Specify the curve direction: either clockwise or counter-clockwise.
- Specify a radius, or enter D to specify the degree of curvature.
Specify a new value, or press Enter to accept the value that is displayed on the command line.
- If the alignment has design criteria applied to it, the minimum value for the current design speed is displayed.
- If the alignment does not have design criteria applied to it, the default value specified in the curve and spiral settings is displayed. For more information, see Curve and Spiral Settings.
NoteTo calculate the radius or degree of curvature using other known curve parameters, enter 'CCALC to open the Curve Calculator. For more information, see Calculating Curve Parameters.
