How to use CAD stairs: Hot topics and practical tutorials on the Internet in the past 10 days
In the field of architectural design, CAD (computer-aided design) is one of the core tools for drawing stairs. Recently, the discussion around "CAD Stair Design" has become more popular on the Internet. This article integrates hot topics, common questions and operation steps in the past 10 days to help users quickly master the skills.
1. Top 5 hot topics in CAD staircase design in the past 10 days

2. Four core steps for drawing stairs in CAD
1.Determine stair parameters: Including step height (usually 150-175mm), step width (260-300mm), ladder width (≥900mm), etc., can be passed
| Stair type | Recommended slope | Applicable scenarios |
|---|---|---|
| residential stairs | 20°-35° | civil buildings |
| public stairs | ≤28° | Shopping mall/hospital |
| emergency evacuation stairs | ≤45° | fire exit |
2.Draw the infrastructure:usePolyline (PLINE)command to create a run profile, or viaArray (ARRAY)Quickly generate steps. Pay attention to setting the layer to distinguish between structural lines and dimension lines.
3.Add details and annotations: Handrail height (≥900mm), anti-slip strips and other details must comply with the "Building Design Code" (GB50352). Annotations should include:
4.3D modeling (optional):useEXTRUDEorLOFTThe command converts a two-dimensional plane into a three-dimensional model, and the material map can be passedMaterial browserAdd to.
3. Solutions to common problems
| Problem description | Solution |
|---|---|
| Inadequate landing width | Check the requirements of the "General Design Principles for Civil Buildings", platform width ≥ stair width |
| Label text overlaps | Use DIMSPACE to adjust label spacing, or decompose labels to adjust manually. |
| 3D model displays abnormally | Check whether the region is closed, or use the REGION command to regenerate it |
4. New trends in CAD staircase design in 2024
1.BIM integration: Revit and CAD work together to realize automatic calculation of stair parameters.
2.AI-assisted design: Some plug-ins (such as Smart Blocks of AutoCAD 2024) can automatically optimize the stair layout.
3.Green building requirements: Consider sustainable design elements such as stair light wells and energy-saving materials.
Mastering these methods and trends will significantly improve the efficiency and professionalism of CAD staircase design. It is recommended to follow Autodesk official updates regularly, or join the designer community to exchange the latest skills.
