Attention engineers! There’s an easier way to conduct Tolerance Analysis for your CAD designs.
Transforming CAD designs into real and tangible parts is not only rewarding on a personal level but also professionally fulfilling. It combines creativity, problem-solving, and hands-on experience, all culminating in the sense of accomplishment that comes from creating something real from an abstract concept.
However, as you already know, physical parts deviate from the idealized representation (the design model) due to many different challenges and manufacturing constraints. Tolerance analysis involves assessing the impact of variations in dimensions, geometries, and other parameters on the final product’s performance and functionality. By utilizing Tolerance Analysis, designers ensure proper fit and alignment of the product components.
Improve Quality & Design Innovation
If the goal is to improve quality and design innovation, enable your engineers to perform comprehensive tolerance stack-up analysis. Traditionally this process is a massive pain i.e. repetitive trial-and-error tasks and tedious testing. This part of the design process can be frustrating and often slows down design teams. However, it doesn’t have to be this way!
The PTC Creo EZ Tolerance Analysis Extension is a dynamic computer-aided engineering (CAE) tool powered by leading Sigmetrix technology. This extension helps designers by creating a faster, more intuitive workflow to assess the impact of dimensional specifications on your product designs before prototypes or production.
The software provides algorithms to help engineers identify the optimal tolerance values that meet the design objectives while considering various constraints. This aids in making informed decisions and reducing the time spent on manual analysis and evaluations.
By considering these variations even earlier in the design process, engineers can make more informed decisions to ensure that the final product will perform as intended. Cheers to reinforcing Closed Loop Manufacturing!

Problem Identification and Resolution
No more flying blind, EZ Tolerance Analysis provides visualizations and statistical outputs that enable engineers to identify potential issues and bottlenecks in the assembly or system. After pinpointing problematic areas, engineers can devise effective solutions – such as adjusting tolerances, redesigning components, or modifying manufacturing processes.
Quick Iterative Design Refinement
Perform your “what-if” scenarios quickly and accurately. Using Sigmetrix technology, get immediate feedback on the effects of tolerance adjustments and trade-off analysis. Engineers can quickly refine and optimize tolerances based on the analysis results, reducing the time required for iterations.
Improved Collaboration
The software facilitates collaboration among multidisciplinary teams involved in the design and manufacturing process. Easily share tolerance analysis data, models, and reports via HTML reports to ensure everyone comprehensively understands design intent and can make informed decisions. Visual and data-backed reports can be shared with the shop floor, suppliers, or other stakeholders, facilitating effective communication and collaboration. Providing clear documentation helps to minimize misunderstandings and costly mistakes, saving time and effort in the design and manufacturing process.
Standards and Specifications Compliance
Ensure compliance with built-in libraries of industry standards and specifications. Engineers can access these libraries to ensure that defined tolerances comply with the relevant standards. Ensure compliance with ASME and ISO standards for your designs and create products that align precisely with customer requirements while operating within acceptable tolerances. This feature helps streamline the process of defining tolerance features by providing pre-defined templates and guidelines that match industry requirements.
Overall, EZ Tolerance Analysis empowers engineers to make data-driven decisions, reduce uncertainty, and enhance the efficiency and quality of the design and manufacturing process. It aids in achieving design objectives, meeting customer requirements, and delivering reliable and cost-effective products.
Back-Up Your cad Designs with Stack-Up Analysis
The technology performs comprehensive tolerance stack-up analysis by applying two methods for increased accuracy and precision- worst-case analysis and statistical analysis.
Worst-Case Analysis: Worst-case analysis, commonly employed for critical components, examines the scenario where each component in the stack-up attains its maximum acceptable measurement.
Statistical Analysis: On the other hand, statistical analysis utilizes statistical distribution models to represent the variation of each component. These distributions are then combined to predict the overall distribution of the assembly measurement.

Related Technologies To Use With Tolerance Analysis
Combine Tolerance Analysis with Geometric Dimensioning and Tolerancing (GD&T) to ensure your designs comply with ASME and ISO standards. Or take your designs even further to contain all the data needed to define the product with model-based definition (MBD). With MBD, your model becomes the source authority across the enterprise. The outcome is shorter product development cycles, reduced costs, and enhanced product quality.

The dynamic duo, Bonnie and Clyde, the perfect pair: Formlabs 3D printers and PTC Creo. Combining these two technology leaders advance businesses to their full potential. When you combine Formlabs 3D printers with PTC Creo, you get an unbeatable combination for creating designs, prototypes and final products.
What is PTC Creo?
PTC Creo is a cutting-edge CAD software with an intuitive user interface that makes it easy to design and optimize your 3D models.
With PTC Creo, you can create high-quality 3D models with powerful features for analysis, visualization, and manufacturing. You can also import existing data from other applications or use the built-in tools to convert 2D drawings into 3D models.
This 3D CAD software solution also has options for live simulation tests to minimize prototyping. You can make sure the parts you are printing have been tested for durability before they even reach the physical world.

What are Formlabs 3D Printers?
Outside of the outcome being a cool physical representation of your design, 3D printing is a fast and cost-effective way to prototype your product.
Formlabs printers use stereolithography technology (SLA) to produce high-quality parts with smooth surfaces, sharp details and no visible layers or seams – all while being fast enough for production-level throughputs. And because they’re so precise, they’re ideal for creating prototypes that look just like what customers expect from final products!
By using 3D printing, you can create prototypes that look like the final product and test them before mass production. This allows you to make changes based on user feedback before investing in tooling for manufacturing. This hardware can save you time and money on low-waste prototypes and production and improve product quality.
