Design 2021: Design like the pros now with the right software

Architects‘ offices, kitchen studios, garden design , Interior design – in many professions it has now become standard to make 3D presentations. And since more and more people work in their home offices, it is also necessary to install suitable design software on the PC that enables both 2D and 3D designs. We explain what so-called 3D CAD software is, who needs it and what you can do with it.

Perfect design with 3D CAD software

When an architect has designed a house, he no longer presents it to the client as a drawing or as a cardboard model true to scale; he creates an absolutely realistic-looking 3D model on the computer. This can be viewed from all sides at the click of a mouse and the house can be entered virtually. A simple keystroke is all it takes and other doors are fitted, the roof is a different colour, an additional panorama window appears as if by magic. It is the same with the interior design. And also with the Garden design 3D presentations have also become commonplace in garden design. Garden novelties or living trends are made visible virtually as if they were „real“, making purchasing decisions and planning much easier. The customer sees what he or she is getting, and changes can be made at the click of a mouse. All this works with good 3D CAD software – this computer-aided technology for drawing, developing and designing replaces manual drafts and automates the process, which represents all objects three-dimensionally.

Two-dimensional vs. three-dimensional - the differences

Basically, every drawing is a two-dimensional model. It is flat, having only height and width as dimensions. 3D images, on the other hand, are three-dimensional, they increase the perception of depth and thus appear more vivid. 2D CAD software creates two-dimensional (flat) objects from given basic objects such as straight lines, circles, ellipses, etc. 2D images are made by drawing three drawings – front view, side view, top view – according to the rules of trigonometry. The 3D CAD software builds up the same geometric objects in three-dimensional form. This allows, for example, sectional views and elevations, technical drawings, architects‘ drafts, interior designs or landscapes to be represented realistically in three dimensions.

3D techniques for the computer

With 3D CAD software, there are different approaches to creating 3D models. The three most common versions are:

  • Wireframe model: With this technique a very high transparency is possible. The wireframe model in the 3D technique requires only a short calculation time.
  • Surface model: Visible surfaces are represented here as coloured, interconnected polygons. To work with a surface model, an edge model or a wireframe model must first be available, in which each individual polygon has its own colour.
  • Solid model: This technique, also called body model, creates 3D models with a very accurate approximation to reality.

Top 3D CAD software for professionals and beginners

There are numerous 3D CAD softwares based on different 3D techniques that are more or less user-friendly. Two of the leading softwares are:

With this software from the manufacturer Avanquest, it is quite easy to create 3D plans of houses and facilities on the PC. The software has an integrated property planner and a topography editor. More than 2,700 prefabricated furnishings, whose details can be individually adapted, leave nothing to be desired. Not only doors and windows can be represented in a wide variety of designs, but also all sanitary and electrical installations, kitchen fittings and furniture. Fireplaces can also be built into the models and even, for example, a garden pool in various shapes and depths. The professional tool for 2D drawings and 3D models convinces with extended mechanical and architectural functions and photo-realistic rendering. The user interface is variable, making it adaptable for lay users as well as professionals. With hundreds of drawing, editing, dimensioning and annotation tools, designs can be quickly rendered and transformed into impressive presentations.
