Computer-Aided Design (CAD) softwareis a tool used to create and modify two-dimensional (2D) engineering drawings and to create, modify, analyze and optimize three-dimensional (3D) designs and models.
CAD is used in a wide range of industries, such as architecture, interior design, mechanical engineering, product development, production equipment for the manufacturing industry, technical sales, layout and many more. (See more in the list below.)
Talk to a CAD expert
In the 1990s, it became common to switch from manual drawing work to 2D CAD. A major advantage of 2D CAD compared to manual drawings was that it was easier to reuse existing drawings.
In the 2000s, many companies started using 3D CAD instead, which provided new opportunities to visualize and optimize products. However, many companies still have 2D files from previous projects that need to be managed in existing CAD solutions.
With 3D CAD programs, such as IRONCADa 3D model provides a more realistic and detailed view of the product.
Among other things, this makes it easier to avoid costly manufacturing errors.
Many people can also more easily understand the design through a 3D model compared to a 2D CAD drawing.
3D CAD models can be mapped onto 2D drawings, where dimensions and tolerances can be added.
All views in a 2D drawing are automatically updated if the 3D model changes, saving a lot of time compared to 2D CAD where changes have to be made manually in all views.
3D CAD models can also be used for different types of analysis, such as strength analysis. These analyses can be used to calculate the stress and strain in the material at a given load.
This makes it possible for a CAD designer to dimension the structure so that it can withstand the loads that the product is expected to be exposed to.
Despite all the benefits of 3D CAD, no CAD solution can replace experience and knowledge of how to design, which is often industry-specific.
A history tree where the different elements of the model (called features) are presented in the order they were created. For example, radii and holes. These are created and modified quickly without locks(parameters and constraints)
Frequently modify imported geometry without features. This method is also flexible, but with less intelligent models.
A history tree here too, where the different elements(features) of the model are presented in the order they were created. These are created and can be modified in certain ways with locks(parameters and constraints)
Consists of simpler form of 3D model with fewer features.
It creates models with surfaces, often carefully defined and controlled using 3D curves. It is used, for example, in the design of cars or consumer products where precise shaping is important.
A common program that focuses specifically on surfaces is Rhinoceros (Rhino) which is known for its advanced NURBS modeling tools, making it ideal for the creation of complex shapes and organic surfaces. Rhino is widely used in industrial design, architecture and art.
All the methods described above are included in IRONCAD and can be mixed in the same file. It is unique and you can solve different needs with one and the same program.
In order to choose a suitable 3D CAD program, it is important to identify what your company will use the software for and what your specific needs are. Your needs may differ from what certain systems are designed for, and you may also have several needs that can be met with the same program. Below are some examples of areas of use where different technologies are used and the associated requirements for the CAD program:
Send us your specifications and we will get back to you as soon as we canThis includes specialized machinery, fixtures, production equipment, industrial maintenance and automation solutions, often consisting of short runs or single solutions. Flexibility and speed are required here, as there is no time to deal with unnecessary steps such as parameters or lockouts.

When customizing machines and equipment for specific customer needs, flexibility is crucial, as you cannot predict what the next customer will want or what the market will demand tomorrow. IRONCAD hybrid modeling with optional constraints and parameters. Unlike SolidWorks, which is based on strict parametric modeling, and Fusion 360, which primarily uses parametric modeling, we help you leverage IRONCAD's unique flexibility for faster results.
Standard productswith variations - for example, products that vary in dimensions and have to follow specific rules (such as balcony railings). This is where investing time in creating parametric models is appropriate.
Assemblieswith different versions and designs - flexibility is needed here, as the design may vary between customers.
When working with models from other 3D systems, it is a great advantage if the CAD program can handle and modify imported designs without requiring history. With modern CAD technology, you can edit and customize models directly, even when history and parameters are not carried over from the original program. This saves time, reduces complications, and makes working with external models more efficient and flexible.
When creating curved sheets, it is important to be able to unfold them into a flat version, where the outline of the flat version is used in DXF 2D format for laser cutting.

Layout involves planning the contents of premises and workshops to create detailed and optimized spaces using computer-aided design. Flexibility without restrictions and parameters is important here, especially when it comes to managing a large number of parts and machines. Too many conditions and restrictions can make planning unclear.
In carpentry, predictable dimensional changes and variations are common. Here, a parametric model can be useful for controlling the dimensions and number of drawers in, for example, a cabinet. Using 3D models and computer-aided drafting/design (CAD), the entire design can be visualized digitally, checked, and adjusted before manufacturing. From these models (e.g., a complete kitchen), everything can be exported to a CAM program that instructs a CNC milling machine, replacing the need for traditional 2D drawings and streamlining production.
CAD programs can be used to create selling, realistic images (renderings) and explanatory language-independent animations, which facilitate the communication of the product to the customer.
3D models can often be analyzed to assess stress and deformation at a given load. For this, there are specific analysis programs that use FEM (Finite Element Method). FEM divides the volume into a three-dimensional mesh and handles stresses via nodes (meeting points) during the calculation. This helps designers understand how the material will behave under different loads and optimize the design accordingly.
Ask for integration adviceIntegration with a PLM system can be beneficial for managing CAD files, documentation and version control. An example is DDM, a PLM solution that streamlines the management of project data and facilitates collaboration between teams. DDM allows project data to be structured and is an excellent tool for industries that need to manage different versions of a design, release, expired design and so on.
Most 3D CAD programs today have the ability to export 3D models to CAM programs, where manufacturing programs are created for, for example, controlled milling machines. An example is WoodLAB, a CAM program that can drastically reduce the time from design to finished CNC milling program, making the production process more efficient.
Flexible, parametric or direct editing
For most design needs, flexible modeling with intelligent features is the most efficient and profitable choice. This provides support to manage concept development, unforeseen late changes and allows greater freedom to test different design options.
Thanks to the intelligent structure of IRONCAD models, there is also the possibility to use parametric techniques when appropriate. This makes it possible to work with fixed dimensions and constraints where precision and control are particularly important.
IRONCAD also offers direct editing, which means that imported 3D files can be modified without the need for a history. This is particularly useful when working with files from other systems and need to make quick adjustments.
Med IRONCAD all these modeling methods - flexible modeling, parametric techniques and direct editing - can be combined in a single file. This makes IRONCAD a reliable choice for those looking for a competent system for fast and efficient product development.
