2D CAD plans and projections

Plans and projections are an indispensable element in all design and conservation work. It is thanks to them that engineers, architects and constructors are able to decipher the necessary information concerning the dimensions and characteristics of a given object or detail. The information contained in such documentation depends on its purpose.

Construction documents include static and strength calculations, structural solutions, etc. Technical documents for machines, machine parts, details, etc. contain information on their linear dimensions, angles, phases and also on the assembly of individual components into a whole.

With computer-aided design, engineers have easier access to libraries, standards, regulations and industry-specific knowledge. This allows many people to work even more efficiently on a given project at the same time, where everyone can focus on their specialisation.

Currently, 2D documentation is created automatically or semi-automatically on the basis of a 3D CAD model. Specialised software makes it possible to create and subsequently edit 2D documentation by adapting the information to the requirements of the project. Documentation based on a 3D CAD model is great for mechanical equipment, but what about digital copies of museum or historical objects?

On the basis of the triangle mesh, i.e. the 3D model obtained by 3D scanning, we are also able to create 2D plans and projections. Special software allows us to measure volumes, linear distances or cross-sections in any 3D model. Such documentation can then be used to reconstruct the object or survey in question.

By way of example, the 3D surface model generated from the point clouds can be used to create the original outlines of the church body, which will first be processed into accurate 2D drawings in vector form for all building components in the church. In this way, two-dimensional documentation elements such as floor plans, floor and ceiling plans, cross-sections and elevations will be created, which can be saved in various formats and with varying degrees of detail depending on the assumptions.
