Create an L-Shape or U-Shape Winder Run

Create an L-shape or U-shape winder run component by specifying the lower endpoint of the run.

The winder run will automatically connect the base and top elevations. (L-shape winder is used for illustration in this procedure.)

To create a winder run

1. Select the winder run component tool and specify initial options and properties.

   See Selecting the Run Component Tool and Specifying Options.

2. On the Options Bar, for Location Line, select either Exterior Support: Left or Exterior Support: Right if you are aligning a run with supports to a wall.

   For aligning a run without supports, Exterior Support: Left and Run: Left have the same alignment behavior (as do Exterior Support: Right and Run: Right).

3. On the Options Bar, clear or select Mirror Preview to change the default winder layout direction.
4. Press Spacebar to rotate the shape of the winder run so the turn is facing the required direction.
5. If positioning the run against a wall or other element, move the cursor near the wall, and notice that the winder stair snaps to position against the wall.
6. Click to place the winder run.
   
7. Use the direct manipulation controls to relocate a run leg or balance the steps between the winder legs, as well as to modify other layout properties.

   See Modifying Stair Components Using Direct Manipulation Controls.

8. Optionally, you can replace winder steps at the beginning and end of the run with straight (uniform) steps.
   • Select the run.
   • On the Properties palette, under Winders, enter the desired number of uniform steps for Parallel Treads at Start and Parallel Treads at End.
     In the following image, 3 parallel treads were specified at the start and end of the winder run.

     
9. Optionally, on the Quick Access Toolbar, click (Default 3D View).
10. On the model panel, click (Finish Edit Mode).
