1. Create a New Stair

Select a new stair from the list of models, and set up general dimensions and parameters, and add components like the strings, handrails and newel posts.

2. General Stair Parameters and Optimisation

How to display and modify the general parameters of your stair, including adjusting the number of steps to optimise riser height, tread width and meet the Stair Rule.

3. Modifying Winders

Winders are tapered steps, so their edges are not parallel to each other. In most European countries, these winders are tapered gradually into and out of the turn. It makes for a safer stair but it takes more time to build. In the UK for example using winders just around the turn is an acceptable way to build stairs. This method makes the staircase easier and faster to build.

We see here how to modify which steps are winders, which are not, and how to adjust the tightness of the turn. We also look at how to manually adjust each winding step so it is as easy to manufacture as possible (not too close to the edge of the newel post for example).

4. Multi Flight Stair Mode: Straight Stair

In this video we will use the multi flight option to create a straight stair. This offers a lot of flexibility in how we can design its shape. You can add multiple flights, modify length, height and width, adjust the angle between each flight and edit the angle of the first and last steps.

5. Multi Flight Stair Mode: Curved Stair

How to use the Multi Flight Stair Mode to create a curved stair of one or more curved elements. Each element can be edited in detail to allow you a lot of flexibility in your project design.

6. StairDesigner Interface: Menus

In this video we look at the StairDesigner interface, in particular the menu bar, quick access tool bar, properties menu and the mouse menu. There are normally a number of ways to perform actions in StairDesigner. We run through your options and familiarise ourselves with the layout of the software.

We also take a look at the Mode window which allows you to display only a specific component. This is particularly useful if that component is hidden in the 2D plan view, for example the stringboard under the handrail. Finally we'll show you how to select specific parts of the stair directly from within the 3D view.

7. StairDesigner Interface: Display

In this video we'll take a look at some common display options it's good to know about. These include: how to change the language in StairDesigner; how to change the units, including using metric or imperial; how to change the background colour of the 3D view, and other 3D view options.

8. StairDesigner Interface: View Modes

Focus on the view menu, and quick access view mode icons. These allow you to view and edit individual components of the stair such as the steps, stringboards, newel posts and handrails. We also take a look at how to turn on and off display of handrails, risers, step numbering and step dimensions, and use of the grid in the 2D view to modify your parts very accurately. Finally, how to revert to the default interface is you need to, sometimes helpful if you've closed a menu you need.

9. General Step Parameters

How to adjust all steps and risers of your stair at the same time. You can add/remove risers, change material, thickness and the step nosing to riser distance. You can also fine tune the step to riser assembly details, including editing the riser into step groove dimensions, sitting the riser behind or on top of the preceeding step, and extending that preceeding step behind the riser.

10. Individual Step Parameters

How to select and individual step and modify its parameters in isolation, with a similar set of options to the General Step Parameters. Editing a single step is particularly useful in certain cases, for example adding a riser to the last step to hide a joist. The Step Type parameter is also covered here, including the difference between a winding and a straight step.

11. General Stringboard Parameters

How to modify the stringboards of your stair. Options include changing the material, thickness and width of your stringers, and setting how far beyond your first and last step you would like them to end. You can also fine tune how the stringboard edge is positioned in relation to the step nosing. A further option allows you to decide whether the strings fit inside or outside your stairwell dimensions, useful for half turn stairs where you would like the central stringboards to sit one above the other.

12. Individual Stringboard Parameters

As well as modifying all strings at once, you can select each individual stringboard and edit it separately. You have a similar set of options as are available within the general stringboard parameters, such as adjusting the material, thickness and so on.

This video focuses on the Type parameter, allowing you to change between curved and straight strings, and a combination of the two. This feature, used in conjunction with adjustments to the string angle, width and string to nosing offset, offers a very good way to edit and optimise each string quickly and efficiently.
