Sigmetrix's GD&T Advisor software in action.
As anyone who’s been deep in the product development cycle knows, GD&T is critical for ensuring that manufactured goods match their models and drawings. However, assigning the right tolerances, datums and dimensions to a model can be tedious and time-consuming, slowing down the product development cycle. But by leveraging the intuitive nature of GD&T Advisor, engineers can quickly apply the correct tolerances and dimensions to their models.
“As an expert in GD&T and tolerance analysis software, and a PTC partner for 26 years, Sigmetrix is a natural choice for a technology collaboration with PTC,” said Brian Thompson, senior vice president, CAD Segment, at PTC. “Sigmetrix has been a great partner with its GD&T Advisor software and CETOL 6σ tolerance analysis solutions, and we look forward to working with them to improve how GD&T is applied to the CAD model. This will alleviate a major hurdle for companies trying to move to a model-based definition environment.”
While not automated, GD&T Advisor is capable of guiding a user through the process of assigning GD&T to a model. Along the way, Advisor can educate users on how to assign the correct amount of GD&T to a model, ensure that the GD&T data is valid and correct and make sure that a model is completely constrained.
Through this step-by-step process, users can narrow the chance of assigning costly and excessive amounts of GD&T to a model and guarantee that drawings, whether they be 2D or 3D PDFs, are not misinterpreted by manufacturers.
