Why Use CAD Data Exchange Software?
Companies that use general-purpose CAD software are often exchanging their data with other team members. This data transfer is helpful so other teams within an organization can work on varying parts of a project. For example, one team may be working on the overall aesthetic design of the CAD model while another team is working on measurements. These two teams must be able to exchange data and use each other’s work. CAD data exchange ensures that this happens in an accurate and efficient manner.
A good use case for this can be applied to any large manufacturing company. Car manufacturing companies, for instance, get their parts from a variety of different subcontractors. While their design company may be located in the United States, the manufacturing part of the job may take place in Asia. These two businesses may use completely different CAD data software, which is why it’s crucial to exchange accurate CAD data between these two business operations using CAD data exchange software.
Who Uses CAD Data Exchange Software?
Manufacturers — Manufacturers across a variety of fields use CAD data exchange software as a means of streamlining the design process of a product. Since manufacturers must work with various subcontractors, CAD data must be transferred effectively to ensure that there are no missteps when it comes to the production of the final product.
Engineers — Engineers use CAD data exchange software to help them throughout the design process. There are plenty of measurements and geometrical data when it comes to designing bridges, roads, tunnels, and other structures. Because of this, engineers must be in constant communication with each other to ensure that measurements and designs are accurate. CAD data exchange software helps engineers by transferring their data over to one another and visualizing a 3D representation of a product.
What are the Different Kinds of CAD Data Exchange Software?
Direct model translation — Direct model translation is a one-step CAD data exchange solution. In a direct model translation, data stored in a product database is transferred directly from one CAD system to another. Within a direct model translation, there is a neutral database that exists between the two databases that are undergoing the CAD data exchange. The neutral database supports all modelling data types so that any data exchange can occur.
Neutral file exchange — Neutral file exchange makes it easier to exchange files with someone who uses a different CAD software. Neutral file formats include IGES, STEP, Parasolid, STL, VRML, DXF, and many more. Many of these transfer data models in different ways and for different purposes; some will be more geared toward the transfer of solid modelling representations, while others are more focused on drawings and other manufacturing functions. Evaluating your business needs will help you find the right solution.
CAD software toolkits — Some third-party services provide low-level CAD translation software toolkits, which allow users to write CAD data exchange software on their own. Users can customize and build their own applications and export the CAD data on their own native systems. This can be a good option if your company is looking to build something from scratch.
CAD Data Exchange Software Features
Transfer geometric information — Perhaps the most important feature of CAD data exchange software is the transferring of geometric information. This includes the dimensions of the engineering process (e.g., the height of a building or the width of a road). If data is not exchanged correctly, the visualization of a final product may end up looking completely skewed. Engineers rely on this geometric data to make decisions on whether or not products need modification.
Transfer CAD metadata — Metadata provides users with information about the data itself. This includes who made the data, who owns the data, and a general description. This is vital to CAD data, since it provides users with information about who designed the product and who to contact in case there is an issue with the engineering measurements. CAD data exchange software includes features that help transfer all of this data from one user to another.
Transfer design intent data — Design intent refers to how objects react to changes within a CAD software. For example, if you were to create a tall building with an arched entrance using CAD software, the design intent would tell the arched entrance to adapt based on how you modify the building height, width, or length. The design intent is important because it saves users plenty of time by not having to modify every aspect of a design manually. Certain CAD data exchange software allows for the transfer of design intent, while others do not have this capability. Since design intent is a crucial part of CAD software, it is important to consider CAD data exchange software that grant this capability.
Transfer application data — Application data includes numerical control paths, geometric dimensioning and tolerancing, process planning, and assembly structure. This data is meant to help manufacturers and engineers accurately define the dimensional requirements for certain parts in the design process. As such, it’s important that this data is transferred over correctly from one CAD software to another. CAD data exchange software helps keep this translation process as accurate as possible.
Geometry comparison — CAD data exchange software gives users the ability to do a geometry comparison of two models. This way users can see what the model looked like before and after the translation and fix any translation problems that are found.
Potential Issues with CAD Data Exchange Software
Data exchange quality — A huge issue users may encounter with CAD data exchange software is data exchange quality. Since each CAD system has its own unique format of describing geometry, oftentimes there is a loss of information that occurs when data is transferred from one CAD data software to another. The best way to mitigate this issue is by using a neutral file exchange that makes it easier to exchange files with someone who uses a different CAD software. However, even this cannot eliminate all potential translation issues. Understanding the way each CAD system describes its geometry will help users see if there is potential for a data exchange problem.
Loss of architectural structure — When data is converted from one CAD software to another, a loss of architectural structure may occur. Features such as building geometry might be altered, and the overall structure of an object may look different. As stated previously, there is no format that can solve all translation issues. This is important to keep in mind when deciding to use CAD data exchange software.
