Dear Community,
This month’s tip comes from a practical modeling challenge: how to cut a beam at a specific point—especially when you need precise documentation for a custom roof truss or timber joinery.
User @Noody asked whether it’s possible to cut a beam at an exact spot, and the solution shared by @Jaime-airc_digital is refreshingly simple.
What this means
When working with structural elements like timber beams or trusses, you often need to show partial cuts, end notches, or connection points. Instead of duplicating geometry or modifying profiles, you can cut beams cleanly using the Opening Tool. This will give you control over where and how the beam is sliced, while preserving element data and behavior.
Here’s how to do it
- Click on the Opening Tool
Go to Design > Architectural Tools > Opening (or use the Opening Tool from the toolbox). - Draw the opening
In the floor plan or 3D view, draw a rectangular or polygonal opening across the beam where you want the cut. - Done
The beam is cut exactly where you need it. The opening remains editable, visible in all model views, and ready for precise documentation, without losing the beam’s native properties.
Extra tips about the Opening Tool
- Openings created with the Opening Tool are parametric and editable, meaning you can adjust dimensions or move them later.
- The tool supports custom shapes and angles, so you’re not limited to rectangular cuts.
- You can use it on individual beams or coordinate placement for consistent cuts across multiple elements.
Thank you, @Jaime-airc_digital, for sharing this quick and effective solution. It’s a great example of using Archicad’s tools to solve real modeling needs.
