How to obtain a cut-away\u00a0drawing from a BIM architectural project in just a few simple steps: here is the step-by-step procedure<\/p>\n

<\/p>\n

BIM software emerges as a powerful ally in streamlining and enhancing the designer’s workflow. This technology enables automatic generation of comprehensive project documentation\u2014from floor plans and elevations to sections, axonometric views, cut-away drawings, reports, and schedules\u2014with a single input, dramatically accelerating the entire design process.<\/p>\n

The cut-away drawing<\/strong> stands as a critical visualization tool, offering profound insights into spatial distribution, furniture arrangement, and material selection, transforming complex architectural concepts into comprehensible visual narratives.<\/p>\n

This approach facilitates more transparent communication of design intent, allowing comprehensive exploration of project variants and enabling more nuanced, informed evaluations before actual implementation.<\/p>\n

Edificius<\/a>, the advanced BIM architectural design software, empowers designers to create precise cut-away drawings through an intuitive, fully automated workflow.<\/p>\n

What is a cut-away drawing<\/h2>\n

A cut-away\u00a0drawing is a three-dimensional representation that combines the clarity of technical axonometry with the informative depth of a section. In this graphic technique, the object or building is ideally \u201ccut\u201d with one or more section planes, allowing the internal parts to be shown without losing spatial reference to the outside. Unlike a simple axonometric view<\/strong> that only shows the external volumes, the exploded axonometric drawing reveals the internal composition, maintaining geometric coherence along the Cartesian axes. The three-dimensionality of the drawing facilitates the reading and understanding of the spatial organization, offering a synthetic and complete view of the project.<\/p>\n

In practical design, the cut-away drawing represents an extremely effective tool for visualizing, analyzing, and communicating the internal articulation of a building. Architects, engineers, and designers use it to highlight functional distribution, the location of systems, the relationship between volumes, and the positioning of furnishings. It is particularly useful in the phase of comparing design variants, validating construction solutions, and communicating with clients and technicians on site. Furthermore, it allows for the identification of spatial or functional criticalities already in the preliminary phase, reducing the risk of errors during the execution phase.<\/p>\n

From a graphic point of view, the cut-away drawing maintains the real proportionality of dimensions along the three main axes (X, Y, Z), without applying perspective distortions. The section can be horizontal, vertical, or inclined, and is often combined with the rotation of the object to maximize the visibility of relevant information. The cut parts are clearly represented, but always in relation to the whole, offering a coherent and readable picture of spatial connections. This type of representation is particularly suitable for documenting and presenting complex buildings, especially in technical and professional contexts.<\/p>\n

Cut-away drawings vs perspective sections<\/h3>\n

The main differences between cut-away drawings and perspective sections lie in the projection geometry<\/strong>. The perspective section<\/strong> mimics the natural vision of the human eye, with parallel lines converging towards vanishing points, generating an effect of visual depth and realism. However, this representation does not preserve real proportions, making direct measurements difficult. In contrast, the cut-away drawing<\/strong> maintains uniform proportions and does not apply perspective deformations: the lines remain parallel and the scales are maintained along all axes. This makes it more suitable for technical drawing, where precision, clarity, and measurability are fundamental requirements.<\/p>\n

Angles in exploded axonometric drawings<\/h3>\n

The axonometric projection can be orthogonal or oblique, depending on the orientation of the projecting rays with respect to the drawing plane. The three main variants of orthogonal axonometry<\/strong> are:<\/p>\n

    \n
  • Isometric<\/strong> \u2013 the three axes (X, Y, Z) form angles of 120\u00b0 between them; all dimensions are represented in real scale, simplifying the reading and production of the drawing;<\/li>\n
  • Dimetric<\/strong> \u2013 two axes share the same scale and inclination, while the third has different angle and scale; it is a more realistic representation compared to isometry, while maintaining good readability;<\/li>\n
  • Trimetric<\/strong> \u2013 each axis has its own inclination and scale; this variant is the most complex to create manually, but can offer a more natural view of the object, useful in specific visual contexts.<\/li>\n<\/ul>\n

    In technical representation, the angles and scales of the axes are regulated by standard conventions, ensuring consistency among the various project documents. Parallel lines do not converge and proportions are respected according to the chosen scale. The section planes are chosen based on the elements to be highlighted: horizontal to show functional distributions per floor, inclined to bring out specific components or particular spatial articulations. The sectioned surfaces are often highlighted with hatching, shading, or conventional coloring. This approach ensures precise and effective technical communication, making the drawing one of the most reliable tools in project documentation.<\/p>\n
