An angle measuring tool or angle finder is a measuring instrument used to determine, transfer or check angles between building components. It is used in construction, interior fit-out, trades and surveying to precisely capture right angles, slopes or complex geometric conditions.
In digital building surveying, angles are often no longer measured manually. Instead, they are derived from point clouds, laser scans or CAD models.
What Types of Angle Measuring Tools Are There?
Classic Try Square
A classic try square is used to check and mark 90-degree angles.
Typical use cases:
- Timber construction
- Interior fit-out
- Metal construction
- Construction site checks
Adjustable Angle Measuring Tool
An adjustable angle measuring tool makes it possible to transfer and measure any angle.
Typical use cases:
- Loft conversions
- Stair construction
- Renovation projects
Digital Angle Measuring Tool
Digital angle measuring tools record angles electronically and provide precise measurement values.
Advantages:
- High accuracy
- Digital documentation
- Direct further processing of measured values
Typical Areas of Application
- Existing building surveys: Rooms and building components that are not at right angles are documented precisely.
- Interior fit-out: Angle information is important for accurately fitting built-in elements and custom-made components.
- Facade and roof renovation: Slopes and connections must be captured exactly to avoid installation errors.
- Existing building modelling: Digital building models reflect the real angle conditions of the existing structure.
Common Mistakes
- Assuming right angles without measuring
- Taking angles from outdated existing building plans
- Capturing too few measurement points
- Ignoring deformations in the existing structure
- Not checking angle data against other building data
FAQ
What is an angle measuring tool?
An angle measuring tool is a tool used to measure, check or transfer angles between building components or surfaces. It may also be referred to as an angle finder or protractor.
When is an angle measuring tool used?
Typical applications include existing building surveys, interior fit-out, facade renovations, roof structures and the surveying of existing buildings.
How accurate are digital angle measuring tools?
Depending on the device and application, digital angle measuring tools can achieve accuracies in the tenth-of-a-degree range or better.
Can angles be determined from laser scans?
Yes. Angles can be precisely calculated and documented from point clouds and digital building models.
