Inherent weaknesses in creating geometry and referencing other parts of a design can cause models to be flaky and unpredictable, or require more work than is necessary to complete a task. However, parametric modeling is not without problems. Other modeling technologies have tried to gain market acceptance, but parametric modeling has proven to be more reliable, more robust and more powerful, enabling engineers and designers to create new products in record time. This is a huge time-saver and helps to reduce design errors. Changing dimension values – or adding, editing, reordering or deleting features – automatically updates a part’s geometry and all associated downstream deliverables, such as assemblies and drawings. The beauty of feature-based parametric modeling is that engineers can create solid models with an ordered list of understandable modeling features (sketch, extrude, fillet, shell, etc.). For over 30 years, feature-based parametric modeling has been the gold standard for creating complex parts and assemblies and is used in production every day by hundreds of thousands of companies worldwide.
