Design 2021: Create like the pros now - with the right software
Architecture firms, kitchen studios, garden design, interior design—in many professions, creating 3D presentations is now standard practice. And since more and more people work from home, it is also necessary to install suitable design software on a PC that supports 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, they no longer present it to the client as a drawing or a scale cardboard model; they create an absolutely realistic-looking 3D model on a computer. It can be viewed from all sides with a click of the mouse, and the house can be explored virtually. A simple keystroke is all it takes to install different doors, change the color of the roof, or make an additional panoramic window appear as if by magic. The same applies to interior design. 3D presentations have also become commonplace in garden design. New garden products or home trends are made visible virtually, as if they were “real,” which greatly simplifies purchasing decisions and planning. The client can see what they will get, and changes can be made with a click of the mouse. All this is possible with good 3D CAD software—this computer-aided technology for drawing, developing, and designing replaces manual drafts and automates the process of depicting all objects in three dimensions.
Two-dimensional vs. three-dimensional – the differences
In principle, every drawing is a two-dimensional model. It is flat and has only height and width as dimensions. 3D images, on the other hand, are three-dimensional; they enhance the perception of depth and therefore look more lifelike. 2D CAD software creates two-dimensional (flat) objects from predefined basic shapes such as straight lines, circles, ellipses, etc. 2D images are created by producing three views—the front view, side view, and top view—according to trigonometric rules. 3D CAD software depicts the same geometric objects in three dimensions. This makes it possible to realistically represent cross-sections, elevations, technical drawings, architectural designs, interior furnishings, or landscapes in three dimensions, for example.
3D Techniques for Computers
There are different approaches to creating 3D models in 3D CAD software. The three most common are:
- Wireframe modeling: This technique offers a high degree of transparency. Wireframe modeling in 3D requires only a short processing time.
- Surface modeling: Visible surfaces are represented as colored, connected polygons. To work with a surface model, you must first create an edge or wireframe model in which each polygon has its own color.
- Solid modeling: This technique, also known as body modeling, creates 3D models that closely approximate reality.
Top 3D CAD Software for Professionals and Beginners
There are numerous 3D CAD software programs based on different 3D techniques and offering varying levels of user-friendliness. Two of the leading programs are:
