Add the most probable floating curve through a series of AutoCAD Civil 3D points, AutoCAD points, existing entities, or clicks on screen.
The location of the curve start point on the attachment entity (1) is determined by the path through the selected regression points (2).
To create a floating curve by best fit using existing entities
- Click the alignment. Click
.
- On the toolbar, click
.
- Select an entity for the start point and direction.
If you select the beginning of the entity, the best fit curve will precede the entity. If you select the end of the entity, the best fit curve will succeed the entity.
- In the Curve By Best Fit Dialog Box, select . Specify the tessellation and mid-ordinate tolerance settings.
- Select one or more of the entities listed on the command line.
Note
You can select several types of entities listed on the command line.
As you select entities in the drawing window, an X marks each regression point and a temporary, dashed curve is displayed in real time.
Note
You must select at least two non-collinear regression points.
- If you selected a profile object, specify the starting and ending station on the Specify Station Range Dialog Box.
- Press Enter to complete the command.
- In the window, use the Regression Data vista to make changes to the regression points.
As you highlight a row in the Regression Data vista, the corresponding regression point in the drawing window is highlighted in red.
- Create the curve:
- Click
to create the curve and keep the vista open.
- Click
to create the curve and close the vista.
