Computer-Aided Design (CAD) is a powerful tool that enables the creation of complex models with astonishing precision and efficiency. However, it is crucial to ensure that these models are not only accurate but also reusable across various applications. This is where CAD quality testing comes into play, an essential process to guarantee the quality and reusability of your models. Let's delve into this subject.

What is CAD Quality Testing?

CAD quality testing aims to identify quality defects related to the design of a model that could impede its reusability in other applications. It also involves ensuring that derived formats of the CAD model, such as IGES, STEP, etc., are equivalent in quality and topology to the master model.

When using the neutral STEP format, adding validation properties to the STEP model can be useful. These properties can be used in the target system to validate the conversion (STEP import).

Why Is It Important?

CAD quality testing is essential for several reasons. First, it ensures that your models can be efficiently and reliably reused in different applications. This can save you time and resources while boosting the efficiency of your design processes.

Secondly, CAD quality testing ensures that the derived formats of your model are of the same quality as the original model. This is especially crucial when working with partners or clients using different CAD systems.

The Role of CADIQ in CAD Quality Verification

When it comes to assessing the quality of CAD models, standard tools might miss critical details. This is where the efficiency and precision of CADIQ come into play.

  • Problem Diagnostics: CADIQ is effective in identifying any disparity or anomaly that could compromise the quality and reusability of CAD models.
  • Pioneering Comparison: The software goes beyond simple checks by offering advanced 3D CAD comparison, essential for validating quality.
  • Format Versatility: Compatible with all major CAD systems and neutral formats, CADIQ adapts to any work environment.
  • Interactive Visualization: Its user interface allows for side-by-side 3D visualization, offering exceptional transparency during verification.
  • Downstream Impact Assessment: The software anticipates the potential impact that any changes could have on downstream processes, an invaluable quality for any business.
  • Ergonomic Operation: CADIQ offers an intuitive interface that can be customized to resemble commonly used CAD systems, thus easing its integration into existing workflows.

Consequently, CADIQ not only emerges as a robust CAD quality verification tool but also as an integral solution for maintaining CAD data integrity. It perfectly addresses the needs and challenges discussed in this context.

Example of CAD Conversion Validation Report with CADIQ

The following PDF example was automatically generated by CADIQ to qualify a model. The CADIQ configuration was set up to identify manufacturing defects. The user can navigate through the 3 quality defects (High-Curvature Surface, Narrow Step, and Thin Solid Volume) and select each item for zooming. Use the transparency option for better visibility.

The PDF template is fully customizable. You can change the logo, add intellectual properties, or add/remove icons, 3D windows, and other fields. Make sure to use Adobe Reader X or higher and enable javascript for correct 3D PDF viewing.


CAD quality testing is a critical process to ensure the quality and reusability of your CAD models. Whether you work with derived formats like IGES or STEP or add validation properties to your models, quality testing can help guarantee that your models are as precise and usable as possible.

CADIQ provides automated validation of your conversions regardless of the methodology. Reports are generated in text format or side-by-side 3D visualization for quick identification of deviations.

Ultimately, CAD quality testing is a practice that can help you optimize your design processes, improve your product quality, and strengthen your customers' trust in your work. Don't hesitate and integrate it into your workflow today!
