2D architectural drawings (floor plans, sections, elevations and site plans) are the most basic architectural drawings. They form the basis for construction drawings (2D) and are also a preliminary stage to drawing the building in 3D. We provide our clients with highly accurate and highly detailed "as-built" architectural drawings for architectural planning, MEP planning, heritage conservation, building documentation, etc. Whatever your project requirements, we produce the exact 2D plans needed to get the job done right.

Floor Plans, Elevations, Sections

We specialize in creating detailed plan sets using 3D laser scanning or tacheometry, depending on the project requirements. We start by accurately measuring the building or object and then 2D-drawing or 3D-modelling the digital impression of it. From the 3D model, we export 2D as-built plans with the desired level of detail. The advantage of this approach is that all the plans are coordinated, as they are generated from the same 3D model. Furthermore, it's easy to add more information to the 2D plans in the future without the need for re-measuring the object. We can derive the required information from the existing scan data and simply supplement the as-built plans with additional layers. The only additional work required is entering the new information into the as-built plans.

As-built measurement

A high-quality 3D survey is important for determining the economic viability of real estate projects, as well as for renovation or redesign purposes. It provides a basis for planning, building applications, heritage office requirements, and rental or purchase contracts. The use of 3D surveys leads to improved planning accuracy, reduces additional work in later stages of a project, and minimizes negative surprises and supplements. Precise measurements, higher information density in plans, and the ability to determine masses are some of the benefits. The need for site visits is decreased, and specialist planners and contractors are relieved from preparing their own measurements. Integrating 3D data into traditional workflows is easier than anticipated and offers numerous opportunities. The supplementation of 2D documents with 3D models or the use of 3D panoramas generated from laser scan data is particularly advantageous. Overall, once the advantages of 3D surveys and laser scanning are recognized, they become indispensable.

Fundamental Concept

Plan 3D was founded with know-how from architecture and carpentry. A high standard of its own work has become part of the company's philosophy. Each service is professionally created with high standards and strictly checked before the data is handed over to the customer. As-built plans and 3D models are created by architects for architects in an attempt to think along with the architect's requirements for a planning basis from the outset. Every line drawn conveys information about a building.

2D Drawings

Level of Detail


Schematic measurement

Drawing tolerance 5-10 cm between CAD drawing and measurement data with orthogonal representations if possible

Areas of application e.g. area calculations, preliminary planning, design planning, mass calculations


As-built measurement as a basis for planning

Drawing tolerance 3-5cm between CAD drawing and measurement data

Areas of application e.g. renovations, conversion planning, building applications, monuments in accuracy class II according to Eckstein


True deformation measurement

Drawing tolerance 2.5 cm between CAD drawing and scan data with deformation-correct representation

Areas of application e.g. renovations, conversion planning, restorations, monuments in accuracy class III according to Eckstein
