MAJ Stair SketchUp Plugin – Full Guide, Features, Real Uses & Download
The MAJ Stair plugin for SketchUp is a powerful extension that helps designers and architects create accurate and customizable staircases quickly. Instead of manually modeling each step, riser, and tread, this tool streamlines the entire process by generating parametric stair geometry based on your preferred inputs. Whether you're working on residential buildings, commercial interiors, outdoor staircases, or complex architectural designs, MAJ Stair gives you greater control and precision with minimal manual effort.
What This Plugin Does
MAJ Stair allows you to generate staircase geometry with variable parameters such as step height, tread depth, number of risers, direction, and rotation. The plugin eliminates repetitive tasks and ensures consistent, professional staircase designs every time. It can also help you explore multiple stair configurations quickly, compare design options, and adapt staircases to architectural changes in your model.
You can use MAJ Stair to create:
- Straight stairs with uniform rise and run
- Curved or spiral stair layouts
- Staircases with custom rise and tread dimensions
- Multi-flight stairs with intermediate landings
- Outdoor steps and landscape stairs
- Interior stairs for residential or commercial projects
By automating stair generation, this plugin saves time and ensures greater accuracy compared to manual methods.
Main Features
1. Parametric Stair Generation
MAJ Stair lets you input precise values for step height, tread depth, total height, and number of steps, creating a controlled and repeatable stair model.
2. Customizable Configurations
You can adapt stair geometry based on design intent—whether you need a compact stair, a wide staircase, or a spiral/curved layout.
3. Multiple Stair Types
The plugin supports straight, L-shaped, U-shaped, and curved stairs to suit a wide range of architectural needs.
4. Clean and Editable Geometry
Stairs generated by the plugin remain clean, grouped, and easy to edit in SketchUp. You can add railings, inserts, and materials without geometry issues.
5. Beginner-Friendly Interface
Even new SketchUp users can start using MAJ Stair immediately thanks to its clear input controls and preview options.
How to Use MAJ Stair
Here’s a simple workflow to create stairs using this plugin:
- Select the starting point for the staircase in your model.
- Open the MAJ Stair tool from the Extensions or toolbar menu.
- Enter the total height, step width, tread depth, and number of risers.
- Choose the stair type (straight, curved, spiral, etc.).
- Preview and adjust parameters if needed.
- Apply the settings to generate the staircase.
Once generated, the stairs are grouped as components you can further edit, place materials on, or duplicate as needed.
Real-World Use Cases
Architects frequently use MAJ Stair for residential and commercial projects where precise staircase dimensions are critical. By automating the design, the plugin ensures that each step follows code-acceptable rise and run dimensions, which is essential for user safety and comfortable transitions. Designers can quickly generate multiple stair options and compare aesthetics and spatial requirements.
Landscape architects and site planners also use this tool when creating outdoor site stairs, terraced walking paths, and stepped platforms for complex terrains. It helps ensure that elevation changes are consistent and visually coherent throughout the design.
