Adding Free Curves and Spirals to an Alignment
The drawing contains a simple alignment consisting of three tangents. In the next few steps, you will add free curves at circles B and C.
- Open Align-2.dwg, which is located in the tutorials drawings folder.
- Set your drawing window so that you can see circles B and C on the surface.
- If the Alignment Layout Tools toolbar is not open, select the alignment. Right-click and click .
- In the Alignment Layout Tools toolbar, click the drop-down list
. Select 
Free Curve Fillet (Between Two Entities, Radius). - As prompted on the command line, click the tangent that enters circle B from the left (the ‘first entity’).
- Click the tangent that exits from circle B on the right (the ‘next entity’).
- Press Enter to select the default value of a curve less than 180 degrees.
- Enter a radius value of 200. The curve is drawn between the tangents as specified.
Add a free spiral-curve-spiral between two tangents
- In the Alignment Layout Tools toolbar, click the arrow next to
. Select Free Spiral-Curve-Spiral (Between Two Entities). - As prompted on the command line, click the tangent that enters circle C from the left (the ‘first entity’).
- Click the tangent that exits circle C on the right (the ‘next entity’).
- Press Enter to select the default value of a curve less than 180 degrees.
- Enter a radius value of 200.
- Enter a spiral in length of 50.
- Enter a spiral out length of 50.Note:
Notice that default values that are shown on the command line. - Exit the layout command by right-clicking in the drawing area.
