Design and simulate your mechanical systems with interactive applications using built-in surface-modeling capabilities and sophisticated optimization routines—one system, one integrated workflow.
Underlying the Mathematica mechanical engineering solution is the world's most accurate symbolic and numeric engine, with highly automated superfunctions for differential equation solving and large-scale eigensystem computation, all with self-checking high-precision arithmetic.
Before you make a Helix Stairs 3D objects, you need to specify the width, height and number ofsteps that are intended. As an example I give a wide diameter of 15 stairs with a height of 26 and the number of steps as much as 13 pieces.

Steps to start is as follows:
- In the top view, the shape of a circle with a diameter of 15, and a transverse line from the center of the circle to the side of the circle.

- Use the array to form a line that wrapped around the whole circle.

- After that, using the trim command, cut all the circles and objects such as reserving a piece ofpizza. : D Use the command pedit to form a polyline object.

- Use the array command again to form an object to circular objects.

- In the front view and use the command 3dorbit, try to view a 3D look. and reserving one object (the others move vertically by 2). Once all the objects to form vertically, you can create a circle on the bottom of the object triangle.

- Use extrude commands to form a 3D object into a form.
