Variety may be the spice of life, but wide-ranging variation in physical dimensions, properties or space between parts is the last thing you want when the components of your product must fit together correctly. You want your parts and assemblies to be within certain tolerances, or acceptable degrees of variation.
Creo Tolerance Analysis Extension (TAE)
Powered by CETOL technology, Creo TAE is an extension to Creo Parametric. With it, you can evaluate the impact of tolerances and dimensioning on product designs before the product reaches prototyping or manufacturing.
Creo TAE provides two analysis tools: worst-case analysis, often used for critical components, which considers what happens when each component in the stack-up reaches the maximum acceptable measurement; and statistical analysis, where each component's variation is modelled as a statistical distribution and these distributions are added together to predict the distribution of the assembly measurement.
Using these tools, designers can produce products that meet customer requirements within acceptable margins — resulting in shorter product development cycles, lower product cost, and higher product quality.
Creo GD&T Advisor for MBD
Creo Parametric 4.0 is the go-to release for model-based definition (MBD). Creo GD&T Advisor is an extension to Creo Parametric 4.0 that provides expert guidance on the application of GD&T, and validates that it has been done correctly. When the model is complete, you can be confident it complies with the relevant standard and is fully constrained. It also improves productivity when applying GD&T, reducing the clicks and time required, and simplifies understanding of complex GD&T standards with readily available guidance at every step. Rulesets included are ASME Y14.5-2009, ISO 1101-2012, and their associated standards.
In a drawing-centric world, non-geometric attributes (GD&T) required to manufacture products — dimensions, tolerances, datums — sit on the 2D drawing. In an MBD world, this information, critical for downstream manufacturing and inspection, must be contained within the model itself, clearly and unambiguously.
Key benefits of GD&T Advisor
- Increases productivity.
- Reduces costs.
- Provides consistency.
- Eliminates mistakes due to human error.
- Improves design communication, reducing the chance of misinterpreted or ambiguous information.
Key features of Creo GD&T Advisor:
- Creation — a feature-centric workflow guides the user through fast creation of annotations.
- Validation — complies with ASME and ISO standards, and fully constrains the model geometry.
- Education — the feature-centric workflow doubles as guided learning for fast, correct annotation.
Creo GD&T Advisor reduces the error between as-designed assemblies and as-produced products through intuitive modelling technologies and advanced visualisation — with a filtered UI, recommended and not-permissible options, an advisor tree, and clear errors and warnings guiding every step.
