In the realm of architectural design, the staircase plays an integral role in connecting levels and facilitating movement within a structure. Its functional importance is undeniable, but its aesthetic value can be equally significant. The handles of stairs, often overlooked, present a unique opportunity to enhance the visual appeal and user experience of a staircase. Rhino, a versatile 3D modeling software, offers a comprehensive toolset for crafting handles that are both stylish and ergonomically sound.
To begin, it is essential to establish the overall design concept for the staircase and its handles. Consider the architectural style of the building, the intended use of the stairs, and the desired aesthetic outcome. Rhino’s intuitive modeling environment empowers designers to explore various shapes and forms with ease, allowing them to visualize and refine their designs until they achieve the perfect balance between aesthetics and functionality.
Once the design is finalized, Rhino’s precision modeling tools come into play. The software provides accurate control over every aspect of the handle’s geometry, from its length and diameter to the shape of its profile. Designers can create complex curves and contours, ensuring that the handles are both visually pleasing and comfortable to grip. Additionally, Rhino allows for the seamless integration of different materials, enabling the creation of handles that combine wood, metal, or other materials for a unique and captivating effect.

Creating the Basic Shape
To create the basic shape of the stair handle, follow these detailed steps:
- Draw a profile curve: Start by drawing a profile curve that defines the shape of the handle’s cross-section. This curve should be drawn on a flat plane, such as the YZ plane. Consider the ergonomics and comfort when designing the shape, ensuring it fits comfortably into the hand and provides a secure grip.
- Extrude the curve: Once the profile curve is complete, extrude it along a path to form the handle’s basic shape. The path should follow the desired contour of the stairs, creating the curvature of the handle.
- Use the Sweep command: As an alternative to extrusion along a path, you can use the Sweep command to create the handle shape. Select the profile curve and a guide curve representing the path of the handle. The Sweep command will generate the 3D handle shape based on these two curves.
Extruding the Handle
1. Select the face of the stair that you want to add a handle to.
2. Click on the “Extrude” command in the “Create” tab.
3. In the “Extrude” dialog box, enter the following settings:
- Distance: The distance that you want to extrude the handle.
- Direction: The direction that you want to extrude the handle.
- Taper: The amount of taper that you want to add to the handle.
4. Click on the “OK” button to extrude the handle.
5. The handle will now be extruded from the face of the stair.
| Setting | Description |
|---|---|
| Distance | The distance that you want to extrude the handle. |
| Direction | The direction that you want to extrude the handle. |
| Taper | The amount of taper that you want to add to the handle. |
Creating a Curved Profile
To create a curved profile for the handle, draw a circle on the edge of the stair and offset it by the desired thickness of the handle. Then, select the circle and use the “FilletEdges” command to round the sharp edges. The radius of the fillet can be adjusted to create the desired curve.
Adding Thickness
To add thickness to the handle, draw a line along the outer edge of the curved profile. Then, use the “Offset” command to create a new curve that is offset from the original curve by the desired thickness. Connect the ends of the offset curve to form a closed loop, and then use the “Extrude” command to create a solid handle.
Rounding
To round the handle, select the edges of the solid handle and use the “FilletEdges” command. The radius of the fillet can be adjusted to create the desired roundness. Alternatively, the “ChamferEdges” command can be used to create a more squared-off look.
| Command | Description |
|---|---|
| FilletEdges | Rounds the sharp edges of a curve or surface. |
| Offset | Creates a new curve or surface that is offset from an existing curve or surface. |
| Extrude | Creates a solid body by extruding a curve or surface along a specified direction. |
| ChamferEdges | Creates a chamfer (angled cut) on the edges of a curve or surface. |
Creating the Bar Support
To create a solid support that will hold the handrail, follow these steps:
1. Draw two parallel lines at the desired width of the support, ensuring they are aligned with the start and end points of the stair incline.
Creating a Surface
2. Select the two lines and create a surface using the “Surface from Lines” command. This surface will serve as the base for the bar support.
Extruding the Surface
3. Use the “Extrude” command to extend the surface along the length of the stair incline. Make sure to specify the desired height of the bar support.
Refining the Support
4. To refine the support’s appearance, consider the following options:
- Chamfering the edges: Use the “Chamfer” command to soften the sharp edges of the support, giving it a more polished look.
- Filleting the corners: The “Fillet” command allows you to round the corners of the support, creating a more organic and visually appealing shape.
- Modifying the cross-section: You can adjust the thickness and shape of the support by modifying the surface’s shape before extrusion.
5. Once you are satisfied with the bar support’s design, proceed to the next step of adding the handrail.
Joining the Handle and Bar Support
Once the handle and bar supports are modeled, they need to be joined together. This can be done using the “Join” command. Select the handle and bar supports, then click on the “Join” command. A dialog box will appear. In the dialog box, select the “Curve” option and click “OK”. The handle and bar supports will now be joined together.
