Point-to-point laser technology

Point-to-point laser technology is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Point-to-point laser technology rather than just read about it. In short: Point-to-point laser technology (PPLT) refers to a technology that enables a user or surveyor to survey or capture a building's geometry in real time or while on site by translating laser range finder data directly into a Computer-aided design (CAD) or building information models (BIM) work station. Applications Most commonly used for as-built and existing conditions documentation or converting the built environment…

Key takeaways

Point-to-point laser technology belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Point-to-point laser technology to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Point-to-point laser technology from memory before moving on to harder problems.

Reference excerpt

Point-to-point laser technology (PPLT) refers to a technology that enables a user or surveyor to survey or capture a building's geometry in real time or while on site by translating laser range finder data directly into a Computer-aided design (CAD) or building information models (BIM) work station.

Applications Most commonly used for as-built and existing conditions documentation or converting the built environment into a digital format.

Benefits PPLT has many benefits in creating BIM or (CAD) models. Entering data directly into a CAD- or BIM-enabled work station allows a user or 'surveyor' to capture and confirm a building's geometry on site. This effectively builds a digital model of a building while it is being measured enabling not only speed but accuracy. Additionally, building in real time can eliminate the need for revisits and also minimizes the need for future interpretation and manipulation of measurements and data by a CAD operator.

Associations Since PPLT mainly deals with building surveying there are a few associations that are building surveying specific. There is the Association of Professional Building Surveyors (APBS) in the United States and the Royal Institution of Chartered Surveyors (RICS) in Britain. Whereas building surveying is offered at the curriculum level in Europe it still is in its nascent stages in the United States.

Certifications Both the APBS and RICS offer certification methods and programs. The APBS has the professional building surveyor (PBS) certifications.

Worked examples

Example 1 — a first encounter with Point-to-point laser technology

Start with the simplest possible case. Write down what Point-to-point laser technology claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Point-to-point laser technology before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Point-to-point laser technology ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Point-to-point laser technology

In research: Point-to-point laser technology appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Point-to-point laser technology in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Point-to-point laser technology is common in secondary-school and first-year university syllabi. It links to neighbouring topics Building engineering, so understanding it makes those chapters shorter.
In everyday life: Look for Point-to-point laser technology outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
